The PVDF/ZnO/CuS heterostructured photocatalysts with excellent photocatalytic performance under UV and visible light irradiation were prepared by hydrothermal and ion-exchange techniques using PVDF nanofiber membranes as the substrate.

A new type of nanofiber membrane was prepared by mixed electrospinning of cellulose diacetate and amino-terminated hyperbranched polymer (HBP-NH2), and glutaraldehyde (GA) crosslinking was used to improve its water resistance and shape retention.
