Title: Innovations of Shengli Qi in Polyimide Fiber Technology
Introduction
Shengli Qi 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, his research focuses on enhancing the strength and modulus of these fibers, making them suitable for various industrial applications.
Latest Patents
One of Shengli Qi's latest patents is titled "Polyimide fiber with high strength and high modulus 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, which effectively addresses the challenges associated with the increased content of BIA. This results in a high-strength, high-modulus PI fiber with a strength of up to 4.5 GPa and a modulus of 201 GPa. The raw materials are readily available, and the continuous spinning process is both cost-effective and efficient, paving the way for industrial production.
Another notable patent involves "Methods of continuously manufacturing polyimide fibers." This patent describes techniques for producing high-quality polyimide fibers suitable for continuous industrial production. The process involves spinning a polyamic acid solution through either a wet or dry-wet method, followed by coagulation, drying, thermal treatment, and stretching to obtain the final polyimide fibers.
