The interphase in polymer composites containing relatively sharp interfaces between the individual phases greatly reduces the performance of these materials. We start our concept of polymer composites without interfaces (inspired natural materials), where a gradient interlayer between the reinforcement and the polymeric matrix is designed to vary chemical and physical properties continuously from those of the reinforcement to those of the matrix. Model simulations with gradient interlayer enable to design the mechanical properties of the interlayer to simultaneously increase both the strength and the toughness of the resulting composite. Proposed gradient interlayer can be realized by using plasma-enhanced chemical vapor deposition with time-dependent deposition conditions enabling to control the interlayer adhesion at both the interfaces with the reinforcement and the matrix. The study will focus on the use of newly developed technological apparatus designed for the preparation of gradient interlayers and their application to fiber-reinforcement composites. The study will be an extensive analysis of chemical and physical properties of interlayers and their application in fiber-reinforced composites. The results and experience will enable to increase performance of polymer composites to a whole new level of smart materials.

Carbon-based materials play a major role in today’s science and technology. In general, an hydrogenated amorphous carbon (a-C:H) can have any mixture of sp3, sp2, and even sp1 sites with the possible content of hydrogen atoms. Atomic polymerization may enable to construct amorphous carbon alloys by atomic (not molecular) processes varying the ratio between sp3 and sp2 hybridizations, varying the specific bond energy of additional (dopant) atoms bound to carbon, and varying the hydrogen content influencing the level of network cross-linking. Within the study, the student will concentrate on amorphous carbon alloys based on polymer-like a-C:H and diamond-like a-C:H and their modifications that may be synthesized as functional materials of controllable physical, chemical, and surface properties by atomic polymerization. Physical properties (mechanical, optical, electronic) of built-up amorphous carbon alloys may result from their chemical structure. Progressively developed amorphous carbon alloys are inevitable for future sophisticated optical, mechanical, and electronic devices.
