Abstract :
Nano-ZnO/PP composite material was obtained by means of melt blending from Nano-ZnO and PP. The melting, crystallization and thermal degradation of Nano-ZnO/PP blend were investigated. The results indicate that the melting peak temperature remained unchanged with the addition of Nano-ZnO. The heterogeneous nucleation effect of Nano-ZnO in composite is notable and the rate of crystallization was decreased. The thermal oxidation degredation temperature of Nano-ZnO/PP coud be remarkably increased by addition of Nano-ZnO which meant the thermal stability of PP was improved. The starting degradation tempreture (To, 5%weight loss) of blending system is higher than that of pure PP for 10.73°C when the mass fraction of Nano-ZnO was 6%.
