Effect of Acrylic Acid Treated Rice Husk Silica on Properties of Poly (butylene adipate-co-terephthalate) (PBAT) Composites

Abstract:

In this work, rice husk silica (RHS), obtained from rice husk waste, was used as a reinforcing filler for preparing PBAT composites. In order to facilitate interfacial adhesion between PBAT matrix and RHS filler, the RHS surface was treated with acrylic acid (AA) at a reaction temperature of 140°C. The RHS to AA weight ratio was fixed while the reaction times were varied between 3-24 h. TGA results and FTIR spectra indicated the appearance of AA molecules on RHS surface. Untreated RHS (U-RHS) and AA treated RHS (AA-RHS) were used to produce PBAT composites. The filler content was 30 wt%. Tensile properties and impact strength of AA-RHS/PBAT composites were higher than those of U-RHS/PBAT composite. As revealed by SEM micrographs, AA-RHS was well dispersed in PBAT matrix and the interfacial adhesion between RHS surface and PBAT matrix was improved.
