Abstract

Conducting composites are the most efficient and commonly used materials for electromagnetic interference (EMI) shielding. The coefficient of thermal expansion (CTE) of a nanocomposite plays a very important role in the use and manufacturing of conducting polymers. However, CTE significantly affects with type and weight percentage (wt.%) of fillers in composites. Nickel (Ni) having good conductivity and permeability is commonly preferred as reinforced material in conducting composite. This work investigates varying wt.% of Ni nanoparticles on the thermal properties of polymeric nanocomposites. The filler content was varied from 0 to 60 wt.%. Ni nanoparticles of 40 nm was used as filler material. This study found an increase in the char yield of the nanocomposites with an increase in Ni content in the poly(ether ketone) (PEK) matrix. A degradation temperature (i.e., 10 % weight loss, T10) was found to increase by 19 °C with increasing Ni content in the PEK/Ni nanocomposite. NC-60 (wt.% of Ni is 60%) has shown higher thermal stability. Above 170 °C there was an increase in the thermal strain of the nanocomposites significantly, but it is observed that it is lowered by the addition of Ni 50 – 60 wt.% as filler material.
