Abstract

See full text

The nanocomposite mixed-matrix membrane is a nanocomposite made from a nanofiller of Halloysite nanotubes or polypropylene-grafted maleic anhydride nano-layered silica dispersed or embedded in a hydrophobic polymer matrix. The Halloysite nanotubes are a 1:1 layered alumino-silicate clay having the chemical formula Al2O3 Si2O4 4(H2O)) formed into multi-layered hollow cylinders having walls that are formed from alternating layers of alumina and silica. The membrane is formed by extrusion of the nanocomposite with stretching over rollers during the extrusion, followed by annealing, cold stretching at room temperature, and hot stretching. The resulting membrane is microporous and can be used as a membrane distillation (MD) membrane for seawater and brackish water desalination.
