Abstract
Although pervaporation (PV) membranes based on crosslinked polyvinyl alcohol (PVA) exhibit high desalination performance, the thermal crosslinking process often takes several hours. Here, we report a microwave assisted method to reduce the crosslinking duration. Moreover, to the PVA crosslinking system, a MOF particle, UIO-66, was added to increase the microwave absorbing efficiency and improve the desalination property. As a result, the PVA crosslinking time decreased to 2 min and the water flux increased by 67% compared with the plain crosslinked PVA membrane.
