Figure 16.20. Conductivity change of a poly(pyrrolephenylsulphonate) film treated with aqueous NaOH solutions of various concentrations. Film thickness is 90 micron A, treated with 50% NaOH B, treated with 2% NaOH and C, treated with 10% NaOH. Adapted from Polymer 11, 899 (1986), with permission of Elsevier Science Ltd., Kidlington.

Novel, flexible, completely organic, polymer dispersed liquid crystal (PDLC) "light valves" were fabricated using two flat pieces of commercial overhead transparency substrates (Nashua j -20) coated with polypyrrole between which a film of commercial PDLC material (Norland Products Co. NOA 65 optical adhesive and BDH Ltd. E7 liquid crystal fluid together with EM. Ind. 15 micron polystyrene spacers) was sandwiched. The optical adhesive was polymerized by exposure to UV light. Thin conducting polypyrrole films of varying controllable thickness were deposited on the overhead transparency.
