The antibacterial PE cling films were successfully obtained through precipitation polymerization and UV polymerization of N,N'-[(4,5-dihydroxy-1, 2-phenylene)bis(methylene)] bisacrylamide (OHABA) monomers, respectively. The inhibition rates of the PE cling films using UV polymerization method against E. coli and B. subtilis were 85.1% and 92.1% respectively, whilst the inhibition rates of the antibacterial PE cling films prepared by precipitation polymerization method against E. coli and B. subtilis were 97.7% and 91.4% respectively. The antibacterial PE cling films using precipitation polymerization method was found to have more excellent antibacterial ability than that using UV polymerization method probably due to the larger surface coverage of OHABA. The POHABA modified PE cling films have great potential in food packaging.
通过沉淀聚合和 UV 聚合 N,N'-[(4,5-二羟基-1,2-亚苯基)双亚甲基)]双丙烯酰胺（OHABA）单体，成功获得了具有抗菌性的 PE 保鲜膜。使用 UV 聚合方法制备的 PE 保鲜膜对大肠杆菌和枯草芽孢杆菌的抑制率分别为 85.1%和 92.1%，而使用沉淀聚合方法制备的抗菌性 PE 保鲜膜对大肠杆菌和枯草芽孢杆菌的抑制率分别为 97.7%和 91.4%。沉淀聚合方法制备的抗菌性 PE 保鲜膜的抗菌能力比 UV 聚合方法更优异，这可能是由于 OHABA 的更大的表面覆盖率。POHABA 改性的 PE 保鲜膜在食品包装中具有很大的潜力。
