Maria Omastova and Ivan Chodak prepared conductive polypropylene/ polypyrrole composites using the method of chemically initiated oxidative modification of polypropylene particles in suspension by pyrrole. In order to prepare the composite, polypropylene particles were dispersed in water-methanol mixture and FeCb was added to be used for chemical oxidation. Addition of pyrrole started formation of polypyrrole particles in polypropylene suspension. The electrical and rheological properties of the composite were compared with polypropylene/polypyrrole composite prepared by melt mixing of pure polypropylene with chemically synthesized polypyrrole and with polypropylene/carbon black composites also prepared by melt mixing. Elemental analysis verified presence of polypyrrole in polypropylene matrix. The conductivity studies show that even a very small PPy amount present in composites results in a significant increase in... [Pg.238]

Electrical properties have been reported on numerous carbon fiber-reinforced polymers, including carbon nanoflber-modified thermotropic liquid crystalline polymers [53], low-density polyethylene [54], ethylene vinyl acetate [55], wire coating varnishes [56], polydimethyl siloxane polypyrrole composites [50], polyacrylonitrile [59], polycarbonate [58], polyacrylonitrile-polycarbonate composites [58], modified chrome polymers [59], lithium trifluoromethane sulfonamide-doped polystyrene-block copolymer [60], boron-containing polyvinyl alcohols [71], lanthanum tetrafluoride complexed ethylene oxide [151, 72, 73], polycarbonate-acrylonitrile diene [44], polyethylene deoxythiophe-nel, blends of polystyrene sulfonate, polyvinyl chloride and polyethylene oxide [43], poly-pyrrole [61], polypyrrole-polypropylene-montmorillonite composites [62], polydimethyl siloxane-polypyrrole composites [63], polyaniline [46], epoxy resin-polyaniline dodecyl benzene sulfonic acid blends [64], and polyaniline-polyamide 6 composites [49].

Iron oxide nanocomposites have been prepared by hydrolysis of iron salts in sulfonated polystyrene resins, mesoporous sulfonated styrene-divinylbenzene copolymer, acrylonitrile-methyl methaciylate-divinylbenzene copolymer, cross-linked high amylose starch, polyimides, polyvinylpyridine, polypyrrole,eellulosies. Nanocomposites of metals (Cr, Mo, W, Fe, Co, Ni) with a variable particle size (2-10 mn), have been prepared from solutions of metal preeursors in a molten polymer (polyethylene, polypropylene, polytetra-fluoroethylene, polyamide, polyaiylate, polycarbonate, polystyrene, polyethers, polyphenyleneoxide, siloxane). There are also many examples of in-situ precipitation of iron oxides in aqueous solution of polymers, such as dextran, PVA, polyethylene glycol, etc. In this case, size dispersion and aggregation are frequent, but they can be minimized by using reverse micelles. ...
