The introduction of glycerol results in the higher amorphous structure in sericin films as evidenced by analysis of attenuated total reflection Fourier transform infrared (ATR-FTIR) spectra, thermogravimetry (TGA) and differential scanning calorimetry (DSC) curves. Sericin films, both in dry and wet states, showed enhanced tensile properties, which might be regulated by the addition of different concentrations of glycerol. The changes in the tensile characteristics and the structure of glycerolated (0-40 wt% of glycerol) sericin films were investigated. ![]() Received: 20 March 2011 in revised form: 2 April 2011 /Accepted: 6 April 2011 /Ībstract: An environmental physical method described herein was developed to improve the tensile properties of Bombyx mori cocoon sericin films, by using the plasticizer of glycerol, which has a nontoxic effect compared with other chemical crosslinkers. ![]() * Author to whom correspondence should be addressed E-Mail: +81815 Fax: +81815.
