目的 解决传统抗菌膜中抗菌剂易从薄膜中流失的问题。方法 用肉桂醛（CIN）与聚乙烯醇（PVA）在浓硫酸催化作用下进行醇醛缩合反应生,生成一种具有抗菌效果的材料（PVA-CIN）。对PVA-CIN进行了化学结构红外光谱检测、热性能（DSC）检测、力学性能检测、光学性能检测以及抗菌性能检测。结果 红外检测结果显示产物中有C—O—C的生成;DSC检测结果显示PVA-CIN的熔点和结晶度都低于PVA;拉伸性能检测显示PVA-CIN的抗拉强度低于PVA;光学性能检测检测显示PVA-CIN的透明度低于PVA,雾度高于PVA;抗菌性测试显示PVA-CIN的抑菌效果优于PVA。结论 肉桂醛（CIN）与聚乙烯醇（PVA）能够在浓硫酸催化作用下发生醇醛缩合反应生成PVA-CIN,PVA-CIN拉伸性能率低于PVA,但抗菌效果优于PVA。
Abstract
The work aims to resolve the issue of antimicrobial agent leaching from conventional antimicrobial films. The sulfuric acid-catalyzed alcohol-formaldehyde condensation reaction was conducted between cinnamaldehyde (CIN) and poly(vinyl alcohol) (PVA), yielding an antimicrobial material denoted as PVA-CIN. Then, PVA-CIN was tested for infrared spectroscopy, thermal properties, tensile properties, optical properties, and antimicrobial properties. Infrared test results showed that there was C-O-C generated in the product. DSC test results showed that the melting point and crystallinity of PVA-CIN were lower than that of PVA. Tensile properties test results showed that the tensile strength of PVA-CIN was lower than that of PVA. Optical properties test results showed that the transparency of PVA-CIN was lower than that of PVA, and the haze was higher than that of PVA. Antimicrobial test results showed that the antibacterial effect of PVA-CIN was better than that of PVA. Cinnamaldehyde (CIN) and poly(vinyl alcohol) (PVA) can undergo an alcohol-formaldehyde condensation reaction under the catalysis of concentrated sulfuric acid, yielding PVA-CIN. Compared with PVA, the resulting PVA-CIN exhibits lower tensile properties but superior antimicrobial activity.
