Abstract
The present invention relates to the production of a hydroxyl polyimide-co-polyimide membrane, the fabrication of a thermally rearranged poly(benzoxazole-co-imide) membrane by thermally treating the hydroxyl polyimide-co-polyimide membrane, and the application of the thermally rearranged poly(benzoxazole-co-imide) membrane to membrane distillation. The thermally rearranged poly(benzoxazole-co-imide) separation membrane has high liquid entry pressure, low thermal conductivity, high permeate flux, and good long-term stability, as well as excellent thermal and chemical properties. Due to these advantages, the copolymer separation membrane can be applied to membrane distillation processes.
