CATECHOLAMINE-BASED VERSATILITY FILM AND A PREPARATION METHOD THEREOF

摘要

The present invention relates to a method for preparing a double-sided film containing the step of forming a film in the interface between air and the mixture of a polymer comprising amine group (—NH) and a compound containing phenol or catechol by exposing the mixture on the air. Particularly, the double-sided film of the present invention is a separation membrane that can separate the interface of liquid phase and gas phase and at the same time can be used as a biomaterial such as a haemostatic and also an waterproof agent. When the film is prepared in a moderate condition by using an enzyme, the film can include proteins and cells, resulting in the multi-functional versatility film that can be useful as a biocatalyst. The versatility film of the present invention, thus, is not expensive and the production method thereof is simple and eco-friendly. Therefore, the film of the invention has a high added-value as a novel separation membrane that can replace the conventional separation membrane.
