The crystallization behavior of semi-crystalline plastics plays a vital role in the development of properties of plastics. The present study examines the effect of addition of 1-5% nano talc filler particles on the nucleation behavior and crystal morphology. Differential Scanning Calorimetry was used to study the dynamic crystallization kinetics of PEEK with different loadings of nano talc filler. The crystalline morphology and non-isothermal kinetics were investigated. Crystallization behaviour was studied using Avrami equation. It is found that the addition of nano-talc enhances the rate of nucleation; however, the growth rate of the crystals reduces.
