文摘

3-Aminopropyltriethoxy silane (APETS), the best silane coupling agent for surface modification of halloysite (Hal) nanotubes. Silane functionalised Hal-PLA bio-nanocomposites were studied for their mechanical, thermal and dynamic-mechanical properties. Tensile and impact strengths were significantly increased for 4 wt% of silane modified Hal-PLA nanocomposites. Thermal stability notably increased for the APTES modified and unmodified Hal-PLAnanocomposites as compared to pure PLA.
