Abstract

A structurally dense hydrogel, with strong hydrogen bonding networks, was formed from poly(vinyl alcohol), sodium alginate, and oligomeric proanthocyanidins, using a combination of freeze-thaw cycles and calcium ion cross-linking. The structure of the hydrogel was characterized by scanning electron microscopy and Fourier transform infrared spectroscopy. Mechanical testing and thermogravimetric analysis showed that incorporation of proanthocyanidins enhanced both the mechanical properties and the thermal stability of the hydrogel. The hydrogel was also demonstrated to have excellent ultraviolet resistance and antioxidant properties. The hydrogel was further shown that this hydrogel is also capable of generating electrochemical reactions, which strongly suggests that this hydrogel has exciting potential in many fields.

摘要

通过冻融循环和钙离子交联相结合的方法，由聚乙烯醇、海藻酸钠和低聚原花青素形成了一种具有强氢键网络的结构致密水凝胶。通过扫描电子显微镜和傅里叶变换红外光谱对水凝胶的结构进行了表征。力学测试和热重分析表明，原花青素的加入增强了水凝胶的力学性能和热稳定性。该水凝胶还具有优异的抗紫外线性能和抗氧化性能。进一步研究表明，这种水凝胶还能够发生电化学反应，这强烈表明该水凝胶在许多领域具有令人兴奋的潜力。
