The effect of DC electric fields on the permeability of side chain liquid crystal polymer membranes.

摘要

Four poly(methyl 4-alkyloxyphenyl-2-methyl-4-chlorobenzoate siloxanes) of variable spacer lengths were synthesized. The four alkyloxy spacers ranged from 3 to 6 carbons. Only the 6-carbon spacer chloro-substituted SCLCP exhibited a liquid crystalline phase, showing a T
