Project summaryProject Objective is to develop physical and chemical and technological basis for the design of a new generation of ultra-light materials with controlled electromagnetic properties on a basis of carbon nano-clusters, including magnetic nano-particles, providing efficient absorption of electromagnetic (EM) radiation in a wide spectral range.
Importance of the Project: As modern technology comes to operation in centimetre and millimetre wavelength regions, it meet a problem of human body protection from harmful influence of EM radiation, as well as a problem of electronic circuits protection from the EM impact and unauthorised access to information flaxes. To solve these problems, new ultra-light materials with controlled electromagnetic properties are necessary. An ability of carbon materials to efficient interaction with EM radiation is already wide used. A discovery of fullerenes has stimulated further research and lead to the synthesis of new types of carbon-based nanostructured materials. Carbon nanomaterials, due to possibility to vary their structure in wide range, high mechanical strength, and unique electric physical properties, can be used as building blocks for the development of new composite materials with high absorption capacity and advanced customer characteristics.
Impact of the proposed project on the progress in the field of development:
For the first time, the Project state a problem to study principles of formation of various nanocarbon-based systems and to reveal the correlation between structure and electronic properties of nanoclusters, being formed through the agglomeration, and their ability to absorb electromagnetic waves. Solution of this problem will result in a significant progress in the field of the design of new composite materials on a basis of different nanocarbon forms.
Theoretical basis created during the project realization and consistent experimental studies will allow synthesising new materials with controlled electromagnetic response. These materials will have advanced working characteristics and will serve as prototypes for the further design of commercial products.
Also, a task of establishing a common scientific language between two scientific communities: physicists and microvawe engineers from one side, and chemists and technologists of carbon nanomaterials from another side, will be solved.
Project participants: The INP team has a leading position in the field of nanoelectomagnetics – a new research discipline joining classical electrodynamics of microwaves and physics of nanostructures. BSUIR is one of the Belarus leading institutions in the field of development of calibration algorithms, automation of measurements in cm- and mm- wavelength region. The participating BSUIR laboratory is accredited as testing laboratory in Belarus national system of metrological attestation and standards. TC "Nanoplan" is a leading developer of industrial technologies for nanodiamonds applications. BIC group has wide knowledge and production abilities for carbon nanomaterials synthesis. NIIC group has a rich experience in the synthesis of multiwall carbon nanotubes and composite materials on their basis, which have predetermined structural parameters and electronic properties. NIIC also is experienced in the study of electronic structure of nanocarbons and structural characterization of their composites.
Expected Results: At the execution of five Project tasks the following results will be achieved:
- Carbon catalytic fibers (CCF), onion like carbon (OLC), multiwall carbon nanotubes (CNT), and composite materials on their basis will be synthesized.
- Physical and chemical studies of structure and properties of carbon nanoparticles and composite materials on their basis will be carried out.
- Theoretical modeling and numerical simulation of electronic structure and electromagnetic response of carbon nanoparticles and composite materials on their basis in microwave and terahertz frequency ranges will be carried out.
- Absorption and attenuation of electromagnetic radiation by composite materials on a basis of different forms of nanocarbons will be experimentally studied.
- A complex of recommendations on the geometrical parameters of inclusions and materials composition, on the choice of polymer matrix, and on the synthesis technology for nanocarbon based electromagnetic coating will be worked out.
The result of a Project will be a physical - chemical and technological basis for the design of ultra-light materials with controllable electromagnetic properties on a basis of carbon nano-clusters, which provide efficient absorption of EM radiation in a wide wavelength region.
Completing of the Project will provide participants with leading position in the field of electromagnetic applications of nanocarbon materials and composites on their basis.
Applications of Project results: Developed materials will find application as new-type light-weight absorbers of EM radiation, required for the design of protection coatings in a wide frequency range. These coatings serve for prevention of unauthorized and disturbing access to electronic devices, banking and information systems, for protection of human body and EM sensors from intense EM radiation, for EM shielding of electronic devices and their users from parasitic and harmful EM radiation, etc.
Meeting ISTC Goals and Objectives: Project meets ISTC Goals and Objectives because it:
- Provides to Project participants who were previously involved in military oriented research, opportunities to redirect their talents to activity on protection of information systems from unauthorized access, and on a development of new efficient composite materials;
- Promotes integration of scientists of CIS states into the international scientific community through joint research, common publications, presentations on international conferences and use of joint intellectual property created during Project execution;
- Supports applied research and n development in the nanomaterials technology for peaceful purposes, including fields of environmental and human health protection;
- Contributes to the solution of national Belarussian and Russian technical problems, in particular, the problem of utilization of some types of ammunition and liquid rocket oxidizer of "melange" type;
- Contributes to the solution of international technical problems, related to the security of informational and banking systems by prevention of unauthorized access and disturbing impact of electromagnetic radiation.
- Reinforces the transition of Project participants to market-based economies, because expected project results met interests of producers of oil production equipment, measuring tools, medical equipment, structured cable systems.
Scope of Activities: the Project duration is 36 months. Total estimated efforts are 9982 man-days. Project includes five tasks. Project has interdisciplinary character and consolidates experts in various fields: theoretical physicists, microwave engineers, chemical technologists, theoretical chemists, synthesis experts, experts in research of nanostructured systems. INP provides the development of measurements methods, analysis and theoretical interpretation of experimental data. BSUIR will provide studies of absorption properties and transmission and reflection coefficient measurements of powders and composite materials in gigahertz frequency region.

Role of Foreign Collaborators: Project will realize in permanent exchange of information with foreign collaborators. Also, foreign collaborators plan:
- shared use of certain equipment and/or test and sample materials;
- cross-checks of theoretical and experimental results;
- testing and evaluation of materials and technologies, developed in the course of the project;
- assistance for project participants to publish results and present them at international meetings;
- conduction of joint seminars and workshops.
Technical Approach and Methodology: At the Project realization, the results will be used obtained by Project participants, including foreign collaborators, during previous joint research and implementation of joint research projects. The principles of formation of nanocarbon-based system will be studied. Namely, the following nanosystem will be under research: detonation nano-diamonds (ND), catalytic carbon fibers (CCF) with different orientation of grapheme fragments (transversal and angular orientation with respect to the fiber axis), multiwall carbon nanotubes (CNT), onion like carbon (OLC). A theoretical analysis of EM radiation interaction with different nanocarbon materials on a basis of fullerene like structures and multiwall nanotubes will be carried out. This analysis will allow the development of an adequate model of the EM parameters of material. Correlations between EM parameters of nanocarbon-based materials with primary blocks structure will be experimentally studied and mechanisms of nanocarbon materials aggregation and cauterization as well as their influence on formation of controllable EM response in new nanocomposite materials will be studied. Physical mechanisms of the anomalous high absorption of EM radiation in OLCs, fullerene-like structures and multiwall CNTs will be investigated as a function of physical and chemical characteristics of carbon materials. Absorption properties of materials will be studied in gigahertz frequency region, which is widely used in telecommunications, as well as in mega- and terahertz ranges. The expected results will allow synthesis of new materials which will provide controlled EM response. The use of carbon nanoparticles will allow varying geometrical parameters of coatings (size, shape and density of carbon inclusions), keeping their high efficiency and giving opportunity to tune materials to attenuation or reflection of EM radiation.
