摘要:
采用刮涂法制备能够应用于薄膜栽培技术中的聚乙烯醇(PVA)-茶多酚(TP)复合水凝胶膜,考察复合水凝胶膜中茶多酚的加入量对膜性能的影响。通过傅里叶变换红外光谱仪(FT-IR)、X线衍射仪(XRD)、耐水压测试及电子万能拉伸试验等手段对水凝胶膜的结构、平衡溶胀度、耐水压力、抗菌性和力学性能等进行表征。结果表明:加入TP对PVA-TP复合水凝胶膜分子间的相互作用有影响,膜内部出现氢键的断裂以及新的氢键的形成; 添加适量的TP能够优化复合水凝胶膜的力学性能、耐水性和抗菌性; 当复合水凝胶膜中TP质量分数为0.6%时,复合水凝胶膜综合性能最好; 相比于纯PVA膜,复合水凝胶膜的拉伸强度、断裂伸长率和耐水压力分别提高了73.5%、71.1%和14.3%,平衡溶胀度降低了12.5%,且有效提高了PVA膜对大肠杆菌与金黄色葡萄球菌的抑菌率。
Abstract:
A polyvinyl alcohol(PVA)-tea polyphenol(TP)composite hydrogel membrane was prepared by scraping method, applied in membrane cultivation filed. The effects of the amount of TP added to the composite hydrogel membranes on the performance of the membrane were investigated. Fourier transform infrared spectroscopy(FT-IR), X-ray diffraction(XRD), water pressure resistance test and electronic universal test were used to characterize the structure, equilibrium swelling degree, water pressure resistance, antibacterial properties and mechanical properties of the prepared hydrogel membrane. Results showed that the content of TP changed the interaction between the molecules of the PVA-TP composite hydrogel membrane, and hydrogen bond breakage and new hydrogen bond formation occurred inside the membrane at the same time. Appropriate content of TP could enhance the mechanical properties and water resistance of the composite hydrogel membrane, and antibacterial properties were improved. When the TP mass fraction in the composite hydrogel membrane was 0.6%, the overall performance of the prepared compsite hydrogel membranes achieved the best performance. Compared with the pure PVA membrane, the tensile strength, elongation at break and water resistance of the composite hydrogel membrane were increased by 73.5%, 71.1% and 14.3%, respectively, and the equilibrium swelling degree was reduced by 12.5%. The polyvinyl alcohol membrane was also improved in terms of antibacterial rate of Escherichia coli and Staphylococcus aureus.
