Title: Enlin Han: Innovator in High-Performance Polyimide Fibers
Introduction
Enlin Han is a prominent inventor based in Beijing, China. He has made significant contributions to the field of high-performance organic fibers, particularly through his innovative work on polyimide fibers. With a total of 3 patents, Han's inventions are paving the way for advancements in material science.
Latest Patents
One of Han's latest patents is focused on 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 preparation process utilizes a gradient temperature reaction method and a one-step continuous preparation method, which effectively addresses the challenges associated with the increased content of BIA. This results in a PI fiber that exhibits remarkable strength, reaching up to 4.5 GPa, and a modulus of 201 GPa. The raw materials are widely available, and the continuous spinning process ensures low costs and high efficiency, making industrial production feasible.
Another notable patent by Han describes methods for continuously manufacturing polyimide fibers. These methods involve preparing high-quality polyimide fibers suitable for continuous industrial production from a polyamic acid solution. The process includes sequential spinning, coagulating, drying, thermally treating, and stretching the resulting fibers, ultimately winding them into rolls.
