Abstract

See full text

The present invention relates to a method for preparing a double-sided film containing the step of 5 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 10 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 15 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.
