Abstract

Abstract:

Inspired by the concept of green chemistry, the biodegradable membrane materials have drawn widespread attentions, and are expected to be alternatives for conventional membrane materials. In this paper, the current status and problems of traditional non-degradable membrane materials were analyzed, several popular biodegradable membrane materials were reviewed, and the applications and the limitations of the biodegradable membrane materials were discussed. Subsequently, the biodegradation mechanism of the biodegradable membrane material was also analyzed, and the biodegradability of the membrane material was explained from the molecular structure. This would help to analyze the essence of the biodegradation of the membrane material, and balance the stability and biodegradability of the membrane material. Finally, the existing challenges and a forward-looking perspective of biodegradable membrane materials were also discussed. With the deepening of research, the biodegradable membrane materials would have broad prospects and far-reaching practical significance.
