Materials Synthesis and Characterization of Nano-Titanium Carbide-Filled Acrylonitrile Butadiene-Styrene Polymer Composites for Electromagnetic Interference Shielding

Abstract

The demand for electronic devices and miniaturization has led to the need for sustainable and cost-effective EMI shielding materials. The advent of new-age technologies in the aerospace, energy, healthcare, telecommunications, and automobile industries demands alternative material candidates that are more cost-effective and environmentally sustainable than the currently used metallic alloys. Conducting polymers is a suitable material choice for EMI shielding in this regard. This study presents a low-cost, environmentally friendly EMI shielding nanocomposites made from regrind ABS and nano-TiC at 5 wt%, 10 wt%, and 15 wt% filler loadings. The composites show a homogenous distribution of nano-TiC particles, increased crystallinity with nano-TiC loading, and improved EMI shielding effectiveness by 16.8% when the nano-TiC filler content is increased from 0 wt% to 15 wt%. These findings could contribute to the development of advanced EMI shielding materials made from recycled ABS/nano-TiC composites for various industrial applications.
