Mechanical Properties and Morphologies of Rice Husk Silica (RHS)/ Poly (butylene adipate-co-terephthalate) (PBAT) Composites: Effect of Silane Coupling Agent
In this work, rice husk silica (RHS), obtained from rice husk waste, was used as a reinforcing filler for preparing PBAT composites. The RHS surface was modified using a silane coupling agent, i.e. γ-methacryloxypropyltrimethoxysilane (MPS), in order to facilitate interfacial adhesion between PBAT matrix and RHS filler. The contents of MPS were varied between 0.5 - 5.0 % based on weight of RHS. FTIR spectra indicated the appearance of MPS molecules on RHS surface. Untreated RHS and MPS treated RHS were used to produced RHS/PBAT composites containing 30%wt RHS. The results showed that mechanical properties of the PBAT composites can be enhanced by treating RHS surface with 2 %wt MPS.
