In this work, Carbon nanotubes with surface treatment and Aluminium Hydroxide (ATH) nanoparticles are incorporated into the polypropylene matrix as Nanofillers to fabricate composites. Thermal properties are investigated by DSC and TGA. Functionalized Multiwall carbon nanotube with ATH nanoaprticles exhibited better thermal properties than individual nanofillers. This nanocomposite should be considered as the new alternative for fire retardant and other thermal properties. Surface treatment of MWCNT (SCNT) is accompanied by using 3 amino propyl tri-ethoxy silanes (APTES). Silanised MWCNT are homogeneously dispersed into the polymer matrix along with ATH. ATH concentration is varied up to 3% for fixed PP with fixed amount of Silanated Carbon Nanotube (SCNT) and the resultant composites were evaluated by DSC and TGA analysis. The results showed that interfacial bonding between Nanofillers, polymer matrix was improved by silane treatment of MWCNT and ATH, degradation rate can significantly be reduced, and thermal stability of polymers can be enhanced without compensating its physical and mechanical properties. Composites consisting of nano-sized inorganic compounds and organic polymers together demonstrating a new class of materials that could exhibit improved performance in all related fields compared to their microparticles counterparts.
