Effects of humidity, imidization history, and thickness on water sorption behavior of poly(p-phenylene biphenyltetracarboximide) films

Poly(p‐phenylene biphenyltetracarboximide) films with various thicknesses were prepared from the poly(amic acid) precursor by thermal imidization at 230–400°C for 1–10 h under a nitrogen atmosphere. The water sorption in the films was measured at 25°C over 22–100% relative humidity using a Cahn micr...
