简述了聚合物纳米复合材料的制备及表征方法,主要论述了纳米填料对可降解生物高分子性能尤其是阻隔性的影响。指出了改善纳米填料的分散程度以及与聚合物的相容性是材料开发的关键,如何制备具有高性价比的功能性降解包装材料(如抗菌性)并满足相关法规要求,将会成为新的发展方向之一。

The preparation and characterization methods of polymeric nano-composites were introduced. The effects of nano-fillers on properties of biodegradable polymers were discussed, especially the barrier properties. It was put forward that the critical issue of polymeric nano-composites development is the dispersion degree of nano-fillers and the compatibility with polymer matrix; the way to prepare higher cost performance packaging with special properties and satisfying requirements of related legal regulations is a new developing direction.
