Effect of Chemical Treatment on Rice Straw Fiber Surface and Properties of Straw/Polylactic Acid Composites

In this work, rice straw fibers were modified using NaOH, KBM-403, and tetraethyl orthosilicate (TEOS), the changes in surface groups of before after modification analyzed by infrared testing. Straw/polylactic composite prepared hot pressing, effects modifiers used on properties these blends studied conducting mechanical thermal performance tests. The results showed that tensile strength fiber composites NaOH KBM-403 increased 20% 21.2%, respectively, compared with unmodified composite, whereas TEOS-modified did not increase significantly. flexural strengths 10.2%, 11.1%, 13.2%. impact 38.5%, 7.6%, 7.6%. analysis show initial maximum decomposition temperatures materials increased, indicating had a higher stability. These are kind potential material for structural applications such as interiors, drywell partitions furniture.
