Abstract: A method for preparing a bifunctional film, including: (a) drying a first polymer solution to form a film to form an anti-adhesion layer; and (b) drying a second polymer solution over the anti-adhesion layer to form a film to form an attachment layer. The first polymer solution includes a first hydrophobic solution and a first hydrophilic solution, and in the first polymer solution, the weight ratio of the solute of the first hydrophobic solution to the solute of the first hydrophilic solution is 1:0.01-1. Moreover, the second polymer solution consists of a second hydrophilic solution.

Abstract: A biodegradable sealant includes: a polyethylene glycol derivative; a photoinitiator; and a solvent, wherein the content of the polyethylene glycol derivative is about 10-75 wt % in the biodegradable sealant. The polyethylene glycol derivative is obtained by a substitution reaction, and in the substitution reaction, the polyethylene glycol is modified with methacrylic anhydride.
