A versatile method for the post-modification of sulfonated polyimides by charge-transfer (CT) complex formation between electron-deficient naphthalenediimide units in polyimide and electron-rich ...

UBE’s UPILEX polyimide films (Figure 1) exhibit a superior chemical resistance when compared to other polyimide materials. They have a UL-94 flammability rating of VTM-0 and have no melting point.

Polyimide composites have emerged as indispensable materials in advanced engineering applications due to their superior thermal stability, excellent flame retardancy and robust mechanical performance ...

A diamine with a side group of pentafluorophenyl, 5FBODA, was synthesized and copolymerized with HFBAPP and 6FESDA to form a fluorinated polyimide, effectively reducing the dielectric constant and ...

Polyimide (PI) nano-aerogels were originally developed to overcome the low thermal stability of traditional nano-aerogels. Combined with improved thermal stability characteristics, PI nano-aerogels ...

Putnam Plastics (Dayville, CT) is introducing clear polyimide tubing for medical applications that require visual monitoring, UV transparency or imaging transmission. Unlike traditional dark, amber ...

Polyimide materials, as Kapton®, are widely used for flexible electronics substrates or as insulators, thanks to their wide range of thermal stability as well as excellent dielectric and mechanical ...

Researchers developed a machine learning model that accurately predicts which polyimide structures will form liquid crystalline phases, speeding up the design of thermally conductive polymers for ...

Sara Greco, R&D Chemist at Valsynthese, part of the SSE Group, covers the beneficial properties of polyimide materials and the key role that aliphatic anhydrides play in the enhancement of those ...
