摘要: Abstract The miscibility of polyaniline (PANI) salts, doped with p-phenol sulfonic acid (PSA) or 5-sulfosalicylic (SSA), poly(2-ethyl-2-oxazoline) (PEOx) was studied by differential scanning calorimetry (d.s.c.) and Fourier-transform infra-red spectroscopy (FTi.r.). D.s.c. measurements show a single glass transition temperature (Tg) for each the blends containing 5–60 wt% PANI. Tg value shifts away from that PEOx increasing PANI content. FTi.r. studies presence specific interactions between polymers. interaction in PEOx/PANI SSA system is stronger than PEOx/PANI-PSA system. Electrical conductivities blends, determined four-point probe, range 10−5 to 10−3 S cm−1.
