聚酰亚胺是60年代发展起来的一类耐高温合成高分子材料。它在—200～+260℃的广阔范围内具有优良的机械性能、电绝缘性、耐磨性、耐辐射性,以及高真空下的难挥发性等,因而广泛应用干电机电器、电子仪表和原子能等工业部门中。同时它又是发展火箭、宇航等尖端技术不可缺少的材料之一,因而引起了人们的普遍重视和大力发展。聚酰亚胺作为耐高温电绝缘材料巳经得到了广泛的应用,其体积电阻率(ρ_v)在10~(17)Ω·cm
Polyimide is a kind of high temperature resistant synthetic polymer developed in 1960s. It has a wide range of -200 ~ +260 ℃ with excellent mechanical properties, electrical insulation, abrasion resistance, radiation resistance, and high volatility under the volatile and so on, so widely used dry electrical and electronic, electronic instruments and Atomic energy and other industrial sectors. At the same time, it is also one of the indispensable materials for the development of cutting-edge technologies such as rockets and aerospace, which has aroused people’s universal attention and development. Polyimide has been widely used as a high temperature resistant electrical insulation material. Its volume resistivity (ρ_v) is in the range of 10-17 Ω · cm
