Latest Patents

Guofeng Tian's latest patents include a high-strength high-modulus polyimide fiber and its preparation method. This invention pertains to the technical field of high-performance organic fiber. The polyimide (PI) fiber is synthesized from 3,3',4,4′-biphenyl tetracarboxylic dianhydride (BPDA), p-phenylenediamine (pPDA), and 2-(4-aminophenyl)-1H-benzimidazol-5-amine (BIA). The molar ratio between pPDA and BIA is maintained at 1:10–3:1. The synthesis process employs a gradient temperature reaction method and a one-step continuous preparation method. This approach overcomes the challenges associated with the increased content of BIA, resulting in a PI fiber with exceptional strength, reaching up to 4.5 GPa, and a modulus of 201 GPa. The raw materials are widely available, and the spinning process is efficient, making industrial production feasible.
