Study on the non-isothermal crystallization kinetics of PVC/Nano SiO2-TiO2 composite resin by DSC
The study of the crystallization process and thermal kinetics using various analytical tools such as DSC analysis can provide a reasonable processing condition for different resin products and further improve their properties. Here, we investigated the non-isothermal crystallization kinetics of PVC/Nano SiO2-TiO2 composites prepared by mixing SiO2 and TiO2 nanoparticles with PVC resin via differential scanning calorimetry(DSC). DSC analysis under different cooling rates confirmed that the crystallization of PVC Nano-composites varied with the cooling rate and with the content of Nano SiO2 and TiO2 nanoparticles. Non-isothermal crystallization kinetics analysis was carried out using DSC analysis data, well-known Avrami equation, Ozawa equation and Mo equation. The model-free method gives the activation energy △E of the crystallization process. It can be seen that the crystallization behavior of PVC/Nano SiO2-TiO2 composite with 3–5% SiO2 and TiO2 nanoparticles is good. These PVC Nano-composites can be used as a belt material for manure handling in chicken plants and as a raw material for plastic clothing for the manufacture of protective clothing.
