中文摘要:
      为改善皮革的特殊气味并提升其应用性能,该研究以玉米醇溶蛋白(Zein)、艾叶香精(AAE)以及普兰尼克F127等为原料,通过反溶剂法制备缓香型玉米醇溶蛋白微胶囊(AAE@ZMs)乳液,再将AAE@ZMs乳液与成膜剂己内酰胺改性酪素复配后应用于皮革涂饰。结果表明,Zein与F127、AAE和戊二醛通过化学交联和氢键相互作用,同时F127和AAE可使Zein中的氨基酸重排并发生荧光猝灭;制得的AAE@ZMs乳液中微胶囊平均粒径约为298.6 nm且具有较好的分散性和稳定性;AAE@ZMs的包覆率和负载率分别可以达到73.2%和5.8%,在良溶剂中释放120 h时的AAE累积释放率约为83.1%。将AAE@ZMs应用于皮革涂饰后,涂饰革样中AAE的释放周期为6周,对金黄色葡萄球菌和大肠杆菌均具有较好的抑制效果,同时涂饰革样还展现出较好的机械性能。
英文摘要:
      In order to reduce the odor of leather and improve its application performances, this study used zein, artemisia argyi essence (AAE) and Pluronic F127 as raw materials to prepare the emulsion of zein microcapsules loading AAE (AAE@ZMs) by anti-solvent method. Then AAE@ZMs emulsion and casein modified by caprolactam (Ca-Cpl) were blended to fabricate composite emulsion and then finish the leather. The results show that zein interacts with F127, AAE and glutaral through chemical cross-linking and hydrogen bonding. Meanwhile, F127 and AAE can rearrange the amino acids in zein and cause fluorescence quenching. The average particle size of AAE@ZMs is about 298.6 nm and the microcapsules have good dispersibility and stability. The encapsulation rate and loading rate of AAE@ZMs can reach 73.2% and 5.8% respectively, and the cumulative release rate is about 83.1% after releasing for 120 h. When AAE@ZMs were applied to the leather coating, the release cycle of AAE in the coated leather sample is 6 weeks. Moreover, the coated leather samples not only show good inhibitory effect on staphylococcus aureus and escherichia coli, but also possess better mechanical behaviors than that of the pristine leather.
