聚酰亚胺泡沫塑料的合成路线及制备工艺

Synthesis route and preparation technology of polyimide foam

综述了主链聚酰亚胺泡沫塑料的各种合成路线和制备工艺中的发泡剂、发泡方法及泡孔结构的控制方法,分析对比了不同合成路线和制备工艺的技术特点;并介绍了侧链型聚酰亚胺泡沫塑料以及聚酰亚胺纳米泡沫塑料的合成路线和制备工艺。聚酰亚胺纳米泡沫塑料的纳米效应及其物理化学性能研究等也将是今后的重点。

This paper reviewed several kinds of synthesis routes and preparation technologies of backbone chain polyimide foams, involving foaming agents, foaming methods and control modes for foam structure. The technical characters of the routes and technologies were analyzed and compared. The synthesis route and preparation technology of the branch polyimide foam and polyimide nano-foam were introduced emphatically. The studies on nano-meter effect and physical and chemical properties of the polyimide nano-foam represent the research focus in this field in the future.
