A Novel Approach to Polymer/Nanosheet Composites and Their Fundamentals

多功能聚合物/纳米片复合材料尚未在聚合物加工和复合工业中广泛应用，主要是由于成本和吸入危害。本项目提出了一种新颖的方法，即在聚合物熔体中嵌入纳米片制备，既消除了吸入危害，又降低了成本；关键是开发两组纳米片插层化合物，它们可以在聚合物加工温度下膨胀，使纳米片在聚合物中剥离和分散。它有望为这些复合材料的结构-性能关系和断裂机制提供新的知识，为工业扩大这项技术和开发新产品提供帮助。

Multifunctional Polymer/nanosheet composites have not yet been widely scaled up in polymer processing and composite industries mainly due to cost and inhaling hazard. This project proposes a novel methodology which embeds nanosheet preparation within polymer melt to both remove the inhaling hazard and lower the cost; the key is to develop two groups of nanosheet intercalation compounds which can expand at the polymer processing temperature, to exfoliate and disperse nanosheets in polymers. It is expected to generate new knowledge of the structure-property relationships and fracture mechanisms of these composites, for industry to scale up this technology and to develop new product.
