Provided is a method of preparing a biodegradable film, which comprises the steps of coating a soluble supporting solution on a substrate, coating a prepolymer solution, pre-drying, crosslinking, and separating. With the technical means, the method can separate the biodegradable film from the substrate smoothly, thereby ensuring the film integrity of the produced biodegradable film.

A method for preparing a biodegradable polyester elastomer includes a following steps comprising: dissolving a predetermined amount of titanium dioxide in an aqueous mixture of sulphuric acid, DI water, and ethanol to form a first solution; refluxing the first solution in a silicone oil bath and a stirring speed of 300-450 rpm at a temperature of 90-100&#xb0; C. to form a second solution; preparing a solid superacid catalyst by drying, grinding and calcining sulfated titania and using this catalyst to produce a biodegradable polyester elastomer.

A printable biodegradable polymer composite includes PGSA, a biodegradable photo-initiator and material selected from the group consisting PCL-DA and PEG-DA uniformly blended together. By adjusting the blending ratio, the elasticity, mechanical properties and degradation patterns may be adjusted for producing a tissue, organ or related bio-product by 3D-printing.
