文摘

The adipic acid (AA) was used as a crosslinking agent to improve the properties of kapok husk (KH) filled soy protein isolate (SPI) biocomposite films. The effects of AA content on tensile properties and morphology of SPI/KH biocomposite films were investigated. The increasing of AA content from 0% to 1.0% has increased the tensile strength and modulus of elasticity of biocomposite films, whereas the elongation at break decreased. Incorporation of 1.0% of AA showed the highest tensile strength and modulus of elasticity of crosslinked biocomposite films. In addition, at 1.5% of AA the tensile strength and modulus of elasticity decreased but elongation at break increased. Thus, at higher AA content it performs plasticity effect to the SPI/KH biocomposite films. The morphology study indicates the crosslinking with AA improved the interfacial interaction between KH filler and SPI matrix.
