The induced circular dichroism (ICD) syndiotactic polystyrene (sPS) chiral films in sPS δ phase were prepared and the chirality of the ICD sPS films upon annealing at different temperature was investigated. The sPS δ crystals in the ICD films trans

A novel optical transition for a hydrogel of polyacrylamide and poly(acrylic acid) random copolymer was observed. The poly(acrylamide-co-acrylic acid) hydrogel is opaque white at low temperature, while it will become transparent gradually or sharply
