Biederman NANOSTRUCTURED PLASMA POLYMERS AND THEIR NANOCOMPOSITES (Charles University in Prague, Faculty of Mathematics and Physics, Department of Macromolecular Physics) e-mail: choukourov@kmf.troja.mff.cuni.cz The methods of structuring of plasma polymers at nano-level are reviewed with special attention paid to deposition by magnetron sputtering, both in normal and in glancing angle configuration. <...> Обсуждаются возможные применения таких материалов Ключевые слова: наночастицы, магнетронное распыление, плазменная полимеризация INTRODUCTION Formation of quazi-polymeric thin films in electrical discharges in organic gases has been known for a long time, however a systematic research on such materials, also called plasma polymers, started in the 1960s [1]. <...> It is generally recognized that plasma polymerization processes are based on formation of free radicals from the molecules of organic precursors by electron impact and/or UV radiation followed by their random poly-recombination. <...> The power delivered to the discharge, the pressure, the flow rate and the molar mass of precursor are the main external parameters that influence the properties of deposited films. <...> If the pressure is sufficiently low (units to tens of Pa) then the probability of gas phase radical recombination is low and plasma polymer is preferentially synthesized heterogeneously on the surfaces adjacent to the discharge in the form of a thin film. <...> At higher pressures, gas phase plasma polymerization becomes dominating and this may lead to the formation and deposition of powders. <...> Nevertheless, in the field of surface modification micro- and nano-particles may play a crucial role as they may be used as building blocks for structuring 26 of the surface. <...> It rather represents an overall insight into the problematics and gives specific examples obtained by the group of plasma polymer physics at the Faculty of Mathematics and Physics, Charles University in Prague. <...> RESULTS AND DISCUSSION As it was mentioned above, formation of particles during plasma polymerization at increased pressures has been studied in the field of dusty plasmas. <...> Recently, a simple gas aggregation source (GAS) was used for fabrication of the nano-particles from hexane vapours with directional deposition of the beam of the nano-particles onto substrates. <...> The deposition <...>
