Abstract

The Carbon Nano Spheres (CNS) derived from areca nuts were synthesized from pyrolysis process and were used as fillers for fabrication of polymer nano composite materials. The filler materials are loaded in 0.05, 0.1 and 0.5 loading percentages. The optimum sample was subjected to heat treatment. The tensile strength, elastic modulus and of elongation were investigated for all samples. The Scanning Electron Microscope (SEM) images revealed the morphological features of optimum samples and hence the uniform dispersion of CNS in polymer matrix. The 0.1 samples showed 10 improvement in Ultimate Tensile Strength (UTS) and 24 improvement in Elastic modulus compared to bare epoxy material. When 0.1 sample was subjected to heat treatment under 200ºC the UTS improved by 23. Hence, CNS reinforced composite materials exhibited unique properties like high strength, less weight and low cost making them suitable for various structural applications such as aerospace, automotive, construction, and electronics industries. © The Polymer Society, Taipei 2024.
