Preparation and properties of modified basic magnesium hypochlorite/ polyvinyl alcohol antibacterial composite film

  • 摘要: 为解决食品、药品等易被细菌污染及其包装造成环境污染问题,通过γ-氨丙基三乙氧基硅烷(KH-550)表面改性碱式次氯酸镁(BMH),并将其与聚乙烯醇(PVA)进行复合,制备改性碱式次氯酸镁/聚乙烯醇抗菌复合膜(改性BMH/PVA抗菌复合膜)。通过SEM、接触角分析、抑菌圈实验和FTIR,证明了BMH的有机改性的有效性。通过调节pH值能够保持改性BMH在PVA中的抗菌性能(抗菌率接近100%)。有机改性BMH含量为3wt%时,改性BMH/PVA抗菌复合膜的断裂伸长率提高了25%,不仅使PVA膜具有抗菌性能,还提高了其韧性。结果表明改性BMH/PVA抗菌复合膜是一种有应用前景的抗菌、可降解材料。
