Poly(aryletherketone) has high thermal stability, chemical stability, and excellent mechanical properties. The demand for PAEK composites are on the rise due to the weight lightening of automobiles and long-term durability quality. PAEK is a semi-crystalline polymer, whose physical properties depend on processing conditions, controlling the processing conditions is a key concept. The isothermal and non-isothermal crystallization behavior was analyzed using DSC, and various theories were applied. In addition, crystallinity according to material types and cooling rate was compared. The quantitative analysis of crystallinity was performed using XRD and FT-IR, and mechanical and electrical properties were analyzed using UTM and DEA. In order to improve heat resistance and friction and wear resistance, PAEK/GNP composites were conducted by adding GNP to PAEK. Thermal, mechanical, and electrical properties were analyzed according to the PAEK material types and GNP contents. |
