More Attentions Paid to Polyimide Film
Due to the dispersion of inorganic filler in the polymer matrix nanometer scale and the strong chemical combination between the matrix, polyimide film has more excellent mechanical properties, thermal stability compared with common kapton film materials. Polyimide film has high insulation performance and corona resistance, too. On the basis of the latest research progress of polyimide film materials, we mainly take a review at the SiO2 / Al2O3, SiO2 / Ti2O3, SiO2, TiO2, Al2O3, and SiC, MMT nano hybrid research progress ofpolyimide film. And it shows that polyimide film is a kind of nanocomposite with organic and inorganic materials. Polyimide film has excellent performance as well as extensive application prospects. But there still exists many problems to be further in-depth study.
The Research progress of polyimide film shows the latest research progress of polyimide film. Research shows that although Chinese scholars have made certain progress on structure and properties, corona resistant mechanism of polyimide film and other issues, there still has not yet key breakthrough. Corona resistance, heat shrinkage rate of the polyimide film, the mechanical strength of kapton film and many other key performances ofChina polyimide film are still far lower than Dupont products. The study of Polyimide film shows that domestic researchers’ understanding of kapton film is still in its infancy whether in theory or manufacturing process .
As for the development situation of Polyimide film, polyimide film plays an important role in the development of high and new technology, especially in the aerospace industry, electrical and electronic industry and the development of information industry. But because polyimide film is a kind of organic polymer whose corona resistance is not high, it limits kapton film application in high voltage generator, high voltage motor, PWM power supply. This article reviews the latest research progress of polyimide film, the synthesis and characterization ofpolyimide film. kapton film has excellent comprehensive performance, it has very important application in the field of high and new technology. However, most of the polyimide is refractory, which gives difficulty toprocessing molding. And the application of polyimide film is limited to a certain degree. Thus the development of easy processed polyimide film has been paid much attention.
