Abstract

In the current study, PTFE (polytetrafluroethylene) matrix is reinforced with different wt% (2%-10%) of Halloysite nanotubes (HNTs). PTFE samples are fabricated with 2 wt% increment and are designated from `B'to `F' and designation `A' refers to neat PTFE. Thermal and mechanical characterization of the fabricated composites is studied. The calorimetric measurements showed enhanced degree of crystallinity of the nanocomposites, which is from 57.83% to 74.7%. The dynamic mechanical analysis results have shown enhanced storage modulus and loss modulus and reduced damping behaviour, without affecting glass transition temperature. Moreover, significant improvements in mechanical properties are observed from the experimental results. The results are discussed and validated with the existing literature. The phase and the fracture morphology of the nanocomposites is studied using scanning electron microscope and discussed herein.
