Preparation of heat-resistant gradient-index polymer optical fiber rods based on poly(N-isopropylmaleimide-co-methyl methacrylate)

摘要

Using the interfacial gel polymerization method, a heat-resistant gradient-index polymer optical fiber (GI POF) was developed based on the copolymer of methyl methacrylate (MMA) and N-isopropylmaleimide (IPMI) as the matrix material and bromobenzene (BB) as dopant. The gradient distribution of IPMI in the GI POF rod was determined by element analysis. IPMI had great advantage in improving glass transition temperature (T-g) and forming a gradient-index profile. There was a significant enhancement in the heat-resistant property in comparison with a conventional GI POF rod. The combination of high thermal stability and easy fabrication makes the novel BBIPMI-MMA system very suitable for heat-resistant GI POF. (C) 2002 Wiley Periodicals, Inc. [References: 11]
