The precise synthesis of materials and devices with tailored complex structures and properties is a prerequisite for the development of the next generation of products based on nanotechnology. Nowadays, the wet chemical technologies for the generation of this type of materials lack the precision to determine their properties and the synthesized materials contain numerous imperfections at the atomic level. The use of bottom-up approaches, which use small fragments of molecules or single atoms as building blocks, is an attractive approach for the synthesis of very complex and yet well-defined material structures. Preparation of hybrid organic-inorganic nanostructures with controlled physical and chemical properties is an example of highly sophisticated materials. Plasma nanotechnology working with the specific interaction of free radicals in the form of neutral and negative ions, which allows controlled design of a material with desired properties based on atomic processes, will be used for the synthesis of such hybrid nanostructures. Development of functional hybrid nanostructures will be directed to controlled interphase in polymer composites. Modeling and experimental data suggest that for such a hybrid organic-inorganic systems be developed nanostructured materials with controlled mechanical properties, wherein the Young’s modulus varies in the range up to two orders of magnitude (10^0-10^2 GPa) for the dimensional scale of less than 100 nm. However, the synthesis must allow simultaneous change in the character of the material from the organic to inorganic phase. The PhD thesis is aimed at preparing a feasibility study of these hybrid nanostructures by plasma nanotechnology and ways of analyzing their properties. The hybrid nanostructures have wide application potential and will be possible to develop them for nanoscale or macroscale functionality in specific hybrid devices.

Dispersion curves for the refractive index and the extinction coefficient will be studied in correlation with chemical properties and film structure. The kinetic mode of ellipsometry will be used to investigate film growth. An effect of film thickness on optical properties will be discussed as well. Differentiation limits for individual layer in layered structures will be determined using ellipsometric measurements and model simulation.

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.
