Abstract
Ultrathin, uniform, pinhole‐free solid polymer electrolyte films of approximately 1 μm thickness were prepared by the complexation of plasma‐polymerized tris(2‐methoxyethoxy)vinylsilane (TMVS) with . The results of FT‐IR, 1H NMR, and 13C NMR measurements indicate that the structure of the plasma polymer is very similar to poly(TMVS), except for the presence of a small amount of what is probably a cyclic group impurity. The glass transition temperature and ionic conductivity of the solid polymer electrolyte depend on the content, and the variation of the ionic conductivity with temperature can be described exactly by using a WLF type of equation. Room temperature conductivities greater than 10−6 S cm−1 (102 Ω cm2 resistance per unit area) were observed.
