Abstract

Poly(phthalocyaninatosiloxane), [Si(Pc)O]n, with the number average degree of polymerization of about 130 was prepared by heating its monomer Si(Pc) (OH)₂, in solid state at 420°C for 42 hrs at 10^-3 torr dynamic vacuum. The [Si(Pc)O]n powder was iodine doped with I₂-benzene solution for 48 hrs. Pure iodine doped poly(phthalocyaninatosiloxane), {[Si(Pc)O]I_y}n, fibers and {[Si(Pc)O]I_y}n/poly(p-phenylene terephthalamide) blend fibers were wet-spun with dry nitrogen-sealed Teflon lined device. D.C. electrical conductivity of the fibers was measured by the four-probe method with an automated charge transport measurement system from 80K to room temperature. It was found that the dependence of conductivity, σ, on temperature, T, could fit a group of thermal fluctuation-induced tunneling (TFIT) equations, and that the dependence of conductivity on volume fraction, φ, of the iodine doped {[Si(Pc)O]I_y}n could fit a group of modified percolation equations.
