Preparation and properties of MMA/fluoro-acrylate copolymers for POF cladding application

플라스틱 광섬유 클래드용 MMA/fluoro-acrylate 공중합체의 합성과 특성 분석

Step index POFs(SIPOF) are composed of core polymers and cladding polymers. Poly(methyl methacrylate) (PMMA) and polystyrene (PS) are normally used as core materials. The refractive index of cladding materials should be less than 2-5 % that of the core material. PMMA and fluorinated polymers are used as cladding materials on PS and PMMA core, respectively$^1$. Cladding materials which have lower refractive index than core materials reflect light at less than critical angle, which is transmitted down the core. (omitted)
