中文摘要:
      目的 介绍海藻酸钠基抗菌复合材料的抗菌机理、特点以及在食品包装方面的应用。方法 重点阐述海藻酸钠的成膜机理、纳米氧化锌的抗菌机理,以及具有特殊层状结构的无机功能材料水滑石的抑菌性能,利用在不同改性方法下水滑石与氧化锌结合形成的增强抗菌结构,探究以海藻酸钠为基材制成的海藻酸钠/水滑石/纳米氧化锌复合膜体系的力学、阻隔和抗菌等性能。结论 绿色食品包装材料在现实生活中倍受关注,将海藻酸钠(能完全生物降解,具有良好的生物相容性和热稳定性的环境友好型材料)与水滑石-氧化锌抗菌剂结合,以增强抗菌复合材料的综合性能,符合国内外研究和开发新型抗菌材料的趋势。
英文摘要:
      The work aims to introduce the antibacterial mechanism, characteristics and application in food packaging of sodium alginate-based antibacterial composite materials. The film formation mechanism of sodium alginate, the antibacterial mechanism of nano-zinc oxide, and the antibacterial properties of the inorganic functional material hydrotalcite with a special layered structure were mainly expounded. The combination of hydrotalcite and zinc oxide was used to enhance the antibacterial properties to explore the mechanical, barrier and antibacterial packaging properties of sodium alginate/hydrotalcite/nano-zinc oxide composite membrane system made of sodium alginate. Food green packaging materials have attracted much attention in real life. Combining sodium alginate, an environmentally friendly material of complete biodegradation, good biocompatibility and thermal stability, with hydrotalcite-zinc oxide antibacterial agent to enhance comprehensive performance of the antibacterial composite material is in line with the trend of research and development of new antibacterial materials at home and abroad.
