| 摘 要： | 采用新型大分子表面处理剂对纳米高岭土进行表面处理,红外光谱仪(FTIR)和光电子能谱仪(XPS)分析表明,大分子表面处理剂和纳米高岭土的表面发生化学键合。将处理后的高岭土与聚乙烯(PE)熔融共混,制备纳米高岭土/PE复合材料,并对复合材料进行表征。将复合材料作为3层共挤出膜的中间层及外层,制备食品包装膜。检测结果显示:用复合材料制备的食品包装膜的力学性能、热封性能、摩擦因数均优于PE膜;复合膜的水蒸气透过量降低46.4%,氧气透过量降低31.7%。 |

| Abstract: | The nano-kaolin was modified by a new kind of macromolecular surface treatment.The results of FTIR and XPS spectra show that the macromolecules are bound on the surface of nano-kaolin particles through chemical bond.Nano-kaolin/PE composites were prepared by melt-mixing process,and the composites were characterized.The composites were applied to food packaging film with three layers as middle and outer layers.The detection results show that the mechanical properties,heat sealing performance and friction coe... |
| Keywords: | macromolecular surface treatment nano-kaolin high density polyethylene linear low density polyethylene food packaging film barrier property |
