Homogeneous Composite Nonwoven Support for High Temperature-Resistant Separation Membranes
High temperature-resistant separation membranes are widely considered in various fields. However, incompetent support layer limits the performance of high temperature-resistant membranes severely. In this work, a homogeneous composite nonwoven support (HCNS) is developed by wet-laid and hot-pressing technology using undrawn polyethylene terephthalate fibers as bonding fibers. The significance of hot-pressing parameters on the performances of the HCNS is investigated, and quadratic regression models are established. The HCNS exhibits a smooth surface (roughness of 118 nm) and a porous structure (porosity of 21.06% and pore size of 6.548 mu m) with a mechanical property (tensile index of 45.80 N m g(-1)). The ultrafiltration membranes supported by the HCNS are prepared from poly(phthalazine ether sulfone ketone), which demonstrates high permeance, high rejection rate, and long-term stability at raised operation temperature, thereby suggesting the potential application of HCNS in high-temperature filtration.
