Nanoporous Polyethersulfone Substrates Improved by Hydrophilic Additives for Composite Membranes in Gas Separation
TS-037290 — Methods to improve morphology of nanoporous polyethersulfone (PES) substrate by incorporating a small amount of hydrophilic additives, such as polyvinylpyrrolidone (PVP), hydroxylated polyethersulfone (PES-OH), and sulfonated polysulfone (SPSf)
Nanoporous polymer substrates are commonly used to provide the mechanical strength for composite membranes in gas separation. The surface property and morphology of the substrate are critical for improving the transport performance of composite membranes. The present invention discloses an effecti…
