Abstract

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.

DSC法研究PVC/纳米SiO2-TiO2复合树脂非等温结晶动力学

利用DSC分析等各种分析工具对结晶过程和热动力学进行研究，可以为不同的树脂产品提供合理的加工条件，进一步改善其性能。本文采用差示扫描量热法（DSC）研究了SiO2和TiO2纳米颗粒与PVC树脂混合制备的PVC/纳米SiO2-TiO2复合材料的非等温结晶动力学。不同冷却速率下的DSC分析证实，PVC纳米复合材料的结晶随冷却速率以及纳米SiO2和TiO2纳米颗粒含量的变化而变化。采用DSC分析数据、Avrami方程、Ozawa方程和Mo方程进行非等温结晶动力学分析。无模型法给出结晶过程的活化能△E。可以看出，含有3-5% SiO2和TiO2纳米粒子的PVC/纳米SiO2-TiO2复合材料的结晶行为良好。这些PVC纳米复合材料可以用作养鸡场处理粪便的皮带材料，也可以用作制造防护服的塑料服装的原料。

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
