【摘要】 综述了聚酰亚胺改性方面的内容。聚酰亚胺具有高强高模、耐辐射、绝缘好等特性,加工流动性及溶解性不佳、易水解等悬其不足。对聚酰亚胺合成改性、结构改性或与其他材料复合后,其原有的一些缺点得到了改善,并赋予了新的功能。另对聚酰亚胺的应用前景做了展望。更多还原

【Abstract】 In this paper, the modification and application of polyimide are introduced. Polyimide is one of the high technological polymers because of its excellent properties, such as heat-resistance, high strength, radiation-resistance etc. Meanwhile it has the poor fluidity, solubility and the decomposition with water. Its deficiencies will be improved when it is compounded with other materials.更多还原
