【 摘 要 】

In this study, the effect of different chemical modifications of stalk sweet sorghum waste on compatibilities in polypropylene matrix has been discussed. Chemical treatments include alkalization-bleaching and alkalization-bleaching-acid hydrolysis treatments. The treatment was objective to improve the surface properties of the sorghum fibre and compatibilities in synthetic polymer matrix. Evaluation of the effect of different chemical modifications was measured with field-emission scanning electron microscope (FE-SEM) and tensile properties. The results showed that the compatibility and tensile strength of composite fibre alkalinization-bleaching treatment were better than untreated composites.
