制备了端羟基聚丁二烯（HTPB）基聚氨酯（PU）-含氟聚合物互穿网络（IPN）膜，以提高HTPB基PU渗透汽化回收丁醇的渗透通量。采用FTIR、TGA、SEM和WCA等手段对IPN进行了表征。当分离膜厚度为21 μm时，在70 °C时，膜的总通量为7.03，分离因子为452.6g/m2 h，与HTPB基PU相比，膜的渗透通量有较大提高，但分离因子有所下降。
Hydroxyl terminated polybutadiene (HTPB) based polyurethane (PU)–fluoropolymer interpenetrating polymer network (IPN) membrane was prepared to improve the permeation flux of HTPB based PU for pervaporation recovery of butanol. The IPN was characterized by FTIR, TGA, SEM and WCA. With a separation membrane thickness of 21 μm, the membrane obtained a total flux of 7.03 with a separation factor of 452.6 g/m2h at 70 °C, the permeation flux improved greatly while the separation factor decreased in comparison with HTPB based PU.
