Preparation and Properties of Straw Fiber/Polylactic Acid Composites

Abstract:

Straw fiber (SF)/polylactic acid (PLA) composites were prepared from SF and PLA. The effects of the composite SF/PLA mass ratio investigated in terms of mechanical properties, water resistance, crystal structure, and thermal properties were investigated. These composites were characterized by scanning electron microscopic (SEM), X-ray diffractometric (XRD), differential scanning calorimetric (DSC), and thermogravimetric analyses (TGA). The results showed that, when the SF/PLA mass ratio was 3/7, the mechanical properties and water resistance of these composites were the best. When the mass ratio exceeded 3/7, the interface compatibility in the composites decreased. As the SF/PLA mass ratio increased, the crystallinity and the heat resistance of the composites were decreased.
