Special Issue Information

Dear Colleagues,

Polyimide has been widely used in microelectronics, optoelectronic, aerospace, filter, electromagnetic shielding and biomaterials due to its excellent thermal and chemical stability, dielectric, mechanical, corrosion and radiation resistance properties. With the increasing demand in various fields, it is necessary to develop high performance functional polyimide or its products. In recent years, advances in the synthesis and modification of polymers and characterization techniques have allowed the design of novel polyimide materials as well as their wide applications. This Special Issue invites contributions addressing, but not limited to, the following aspects of high performance functional polyimide, such as the synthesis and preparation of high performance or functional polyimide, structure–properties relationship of high performance or functional polyimide, processing of polyimide, modification and functionalization of polyimide, applications of high performance or functional polyimide, polyimide film, fiber, aerogels and other functional materials. The above list is only indicative and by no means exhaustive; any original theoretical or simulation works or review articles on high performance functional polyimide are welcome.

Colorless polyimides (CPIs) with outstanding mechanical properties are essential materials in the production of flexible display panels, foldable windows, and even spacecraft cockpits. This paper specifically elaborates that the Morkit unit, and azo and nitro chromophores are important factors contributing to yellow PI, together with the well-known charge transfer complex (CTC) theory. Three diamine monomers, two anhydrides monomers, and three blockers were used to inhibit chromophores formation and, thus, obtain CPI films. The cut-off wavelength was blue-shifts to 334 nm and the transmittance is improved to 98.9% in the UV–vis range. Mechanical and thermal properties of the CPI films are not reduced through coupling effects of the blockers. Therefore, the inhibition method of the Morkit units and chromophore groups is a promising process for preparing CPIs to be used as flexible display materials. Full article
