Ti3C2/PVDF membrane for efficient seawater desalination based on interfacial solar heating

The photothermal material of Ti3C2 was synthesized by etching Ti3AlC2 with hydrofluoric acid. The as-prepared Ti3C2 was deposited on a polyvinylidene fluoride (PVDF) membrane via vacuum filtration to form a Ti3C2/PVDF membrane, which was used for seawater desalination in the next step based on inter...
