However, gelatin does have an important merit that it is a cheap biopolymer.
By some posttreatment or mixed with another (synthetic) biodegradable polymer [11], gelatin can be used alone or as a blend component to prepare nanofibrous membranes for tissue scaffolds, wound healing and health caring devices, and other biomedical applications.
In this paper, the electrospinning of gelatin has been achieved by dissolving it an uncommonly used solvent, 2,2,2-trifluoroethanol.
With this solvent, the gelatin solutions of mass concentrations in a range of 5–12.5 wt% have been successfully electrospun into ultra fine fibers at room temperature. However, further
lower or higher concentrations were difficult to process.
