Shellac is an oligomer (Mw≈1000) constituted of the fatty acid and sesquiterpene,with excellent biodegradable.Owing to the low molecular mass,the material made of pure shellac present lower mechanical properties.Meanwhile,attributing to the shortage of amine group,the material made of shellac also show weakly biocompatible.The gelatin was introduced to the shellac-based material to reinforce the mechanical property,and improved its biocompatibility.The freezing polymerization was employed to build the shellac/gelatin foam with good mechanical property and excellent biodegradable which had great potential application in the 3D cell cultivation.
