doi:10.7506/spkx1002-6630-201308008

Abstract

Abstract: Using albumin as raw material and fixing nano-SiOx addition amount, nano-composite films were achieved through casting technique. Single factor and response surface tests were used to explore the optimal preparation process of composite film. Regression models of tensile strength (TS), elongation (E) and water vapor permeability (WVP) were established using albumin content, plasticizer content, intensifier content and crosslinker content as response factors. The optimal preparation conditions were albumin content of 8 g/100 mL, plasticizer content of 3.09 g/100 mL, intensifier content of 0.55 g/100 mL and cross-linker content of 0.71 g/100 mL. Under the optimal conditions, the properties of composite films were (3.492 ± 0.183) MPa, (58.300 ± 2.415)% and (5.570 ± 0.077) g?mm/(m2?d?kPa), which were close to the predicted values.

Key words: albumin film, nano-SiOx, response surface
