Abstract

Abstract: The thermo-mechanical performance of halloysite nanotubes (HNTs) reinforced polymer nanocomposites has been investigated in this work and their properties are compared with enticing carbon nanotubes (CNTs) and carbon nanofibers (CNFs) reinforced polymer nanocomposites. Excellent dispersion of HNTs in Poly(methyl methacrylate) (PMMA) matrix has been observed which might be a reason for comparable heat absorption capacity and mechanical properties of HNT-PMMA composites to that of CNT-PMMA composites. Instead, HNTs are biocompatible which makes it more suitable with biocompatible polymer to extend the applicability of these composites for diverse bio-medical applications. It has also been revealed from dynamic behavior of these nanocomposites that suitability of particular nanofiller is dependent on requirement of operational parameters. Highlights: Synthesis of PMMA-CNT/HNT/CNF nanocomposites via melt mixing technique. PMMA-CNT composites shown around 72% increase in strength and 5.7% improvement in ductility. Addition of HNTs shown large improvement in ductility of these composites. Incorporation of CNTs improved the thermal decomposition temperature by 10 °C. DMA shown that distinct rheological properties of composites under varying frequency and strain.
