Effect of drying temperature on sericin film structure

Silk sericin was used as material to prepare sericin film varying drying temperatures.The effect of drying temperature on the structure of sericin film was researched by using X-ray diffraction,infrared spectroscopy,and DTA.The results showed that drying temperature had obviously influence on aggregation structure of sericin protein in temperature range of 30-(100 ℃.) The aggregation structure dried at(30 ℃) was mostly amorphous.With the temperature increasing,the tightness of sericin protein′s aggregation structure was increased and,became obvious above(80 ℃.)The important temperature point for significant modification of sericin protein structure was about(40 ℃.)
