N. Nugay et al., CONDUCTING PROPERTIES OF IODINE-DOPED POLY(4-VINYLPYRIDINE)-POLY(DIMETHYLSILOXANE) BLOCK-COPOLYMERS, Polymer, 35(2), 1994, pp. 243-245
Block copolymers of various compositions, consisting of poly(4-vinylpy
ridine) (P4VP) and poly(dimethylsiloxane) (PDMS) blocks, were prepared
by anionic polymerization. These samples were modified by the additio
n of various amounts of iodine in solution. The electrical conductivit
ies of the doped materials were measured by the four-probe method and
were found to be as high as 10(-5) S cm(-1). The optimum ratio of iodi
ne to pyridine which gave the highest conductivity was determined.
