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.
