Effects of Heat Treatment on the Morphology and Performance of PSU Electrospun Nanofibrous Membrane
Source abstract
Abstract
With excellent permeability, large specific surface area, high porosity, and outstanding internal connectivity, polysulfone (PSU) electrospun membrane can be a good filter media. However, the asspun PSU electrospun membrane is poor in mechanical properties with bulky structure, and the binding force between fibers is low. In this paper, the effects of heating time, temperature, and heating method during heat treatment on the morphology, mechanical properties, and chemical stability of PSU electrospun membrane were studied and analyzed. The results show that the PSU membrane would achieve the best performance when treated at 190°C for three hours with tension heating. After tension heating, dimensional stability, appearance, integrity, and mechanical properties improved; chemical stability in the alcohol solution increased greatly, but the membrane shrunk quickly in the acetone solution.
