Projekt je zaměřen na syntézu a charakterizaci vrstev plazmových polymerů využitelných jako kompatibilní a multifunkční mezivrstvy ve vlákny-vyztužených polymerních kompozitech bez rozhraní, které napodobují přírodní systémy. Jedná se o novou koncepci, kde kompozitní složky, vlákno a polymerní matrice, jsou propojeny pomocí gradientní mezivrstvy, jejíž fyzikálně-chemické vlastnosti se spojitě nebo kvazi-spojitě mění od vlastností vlákna k vlastnostem matrice v rámci řízené syntézy. Na základě modelových simulací musí být gradientní mezivrstva navržena a poté syntetizována na povrchu vlákna tak, aby vzniklo pevné, ale houževnaté propojení mezi vláknem a polymerní matricí vedoucí k významnému zvýšení užitných vlastností (pevnost, houževnatost) kompozitu. Tato koncepce gradientní mezivrstvy má vysoký aplikační potenciál pro libovolný hybridní materiál v elektronických, optických, mechanických a biomedicínských zařízeních.

Description in English
The project is aimed at synthesis and characterization of plasma polymer films utilizable as compatible and multifunctional interlayers in fiber-reinforced polymer composites without interfaces that mimic natural systems. This is a novel conception, where the composite constituents, the fiber and the polymer matrix, are combined together by gradient interlayer, whose physicochemical properties are continuously or quasi-continuously varied from those of the fiber to those of the matrix under controlled synthesis. Based on model simulations, the gradient interlayer has to be designed and synthesized on fiber surface to form strong but tough link between the fiber and the polymer matrix resulting in significant increase of composite performance (strength, toughness). Such conception of the gradient interlayer has a high application potential for any hybrid material in electronic, optical, mechanical, and biomedical devices.
