Mechanical Properties of Polymer Composites Using Plasma-Modified Mica Filler... 

As presented in the introduction, the nature of the substrate used for the above-described electrostatic layer-by-layer deposition is not cmcial, as long as it is charged. For example, PAH/PSS multilayers have been prepared on plasma-treated glass [85,86], as cleaved mica [87], silicon functionalized by 3-aminopro-pyldimethoxysilane [88], surface-oxidized poly(4-methyl-l-pentene) [89], chemically modified poly(chlorotrifluoroethylene) (PCTFE) [90,91], plasma-modified poly(tetrafiuoroethylene) (FIFE) [92,93], chemically modified as well as untreated poly(ethylene terephtalate) (PET) [94], gold surfaces modified with mer-captopropionic acid [76], and many others. PAH/PSS multilayers have also been grown on chemically modified polystyrene [95] and melamine formaldehyde latex particles [96,97]. Multilayer assembly on latex particles was either accomplished by adsorption from solutions of high polyelectrolyte concentration with... 

In order to modify favorably the interaction balance at PE/PS contacts, mica was subjected to LMP treatments using E and S monomers in sequence. In principle, the generation of plasma-polymerized ethylene (PPE) and styrene (PPS) on the mica surface might... 

It is evident that monomer pressure and plasma duration strongly affect the modifying influence of mica filler in the PS stock. An optimum monomer pressure in the 2-3 torr range is indicated, the tensile Impact being particularly sensitive to this variable (Fig. 4). Treatment time is even more significant (Fig.
