Cryochemical synthesis and physical-chemical properties of nano-dispersed metallopolymers

New nanodispersed metallopolymer (Ag, Na, Mg, Pb, Mn, Ca, Sm) films have be en obtained via low temperature codeposition of metal and reactive paraxyly lene monomer vapours at 100 K. Electric conductivity of the films were stud ied during the components codeposition,upon the samples annealing at 80-300 K and maintaining rat constant temperature. With a rise in nanoparticle co ncentration in the polymer matrix, the conductivity tends to increase. The conductivity may be determined by tunnel transfer of charge carriers from o ne nanoparticle to another through a thin dielectric layer (up to 50 nm) of polymer matrix.
