摘要

研究了 PVA(聚乙烯醇)/TP(茶多酚)复合材料的结晶动力学行为。结果表明,在 PVA 复合材料中添加 TP 成分会降低结晶度(%),从而形成较低的 Avrami 指数 n。随后,通过分析氢键因子 F%与不同结晶动力学参数(包括 Avrami 指数 n、Zt、α 和 F(T))的关系,进一步定量评估了 PVA/TP 复合材料、纯 PVA 和非氢键(非氢键)对此类复合材料中氢键的影响。结果表明,阿夫拉米指数 n 和 α 的关系为 n = -a1 + b1FPVA/TPH-bonding-c1F2PVA/TPH-bonding 和 α = -a5 + b5FPVA/TPH-bonding-c5F2PVA/TPH-bonding 。Zt 分别描述为 Zt = a2-b2e(FPVA/TPH-bonding-c2)/d, Zt = -a3 + b3FPVAH-bonding-C3F2PVAH-bonding 和 Zt = a4(Fnon-H-bonding-b4)c4 等函数。F(T) 表示为 F(T) = a6-b6FPVA/TPH-bonding+c6F2PVA/TPH-bonding ,其中 a、b 和 c 为正常数。

Quantitative evaluation of the hydrogen bonding effects on the crystallization kinetics of poly(vinyl alcohol)/tea polyphenol composites

Quantitative evaluation of the hydrogen bonding effects on the crystallization kinetics of poly(vinyl alcohol)/tea polyphenol composites

The crystallization kinetics behaviors of PVA (poly (vinyl alcohol))/TP (tea polyphenol) composites were studied. Results showed that the addition of TP component in PVA formed composites would reduce the crystallinity (%), leading to the formation of a lower Avrami exponent, n. Under the fixed cooling rate condition, the n values of Avrami and α values of Mo are both higher for the above composites with TP ingredient at 10–20%. Subsequently, the influence of the hydrogen bonding (H-bonding) in PVA/TP composites, pure PVA and non-hydrogen bonding (non-H-bonding) in such composites were further quantitatively assessed by analyzing the H-bonding factor, F%, in relation to different crystallization kinetic parameters including Avrami exponent n, Zt, α and F(T). Results showed that the relationship of Avrami exponent n and α were presented as n = -a1 + b1FPVA/TPH-bonding-c1F2PVA/TPH-bonding and α = -a5 + b5FPVA/TPH-bonding-c5F2PVA/TPH-bonding. The Zt was described as the functions like Zt = a2-b2e(FPVA/TPH-bonding−c2)/d, Zt = -a3 + b3FPVAH-bonding-C3F2PVAH-bonding, and Zt = a4(Fnon-H-bonding-b4)c4, respectively. The F(T) was presented as F(T) = a6-b6FPVA/TPH-bonding+c6F2PVA/TPH-bonding, where a, b and c are positive constants.

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.
