抄録

Graded-index plastic optical fibers (GI POFs), composed of doped polymers, have advantages over conventional glass optical fibers (GOFs), but need to be developed further for practical application. Here, a variety of aromatic sulfide dopants were synthesized and their effects on the refractive indexes and glass transition temperatures (Tg) of poly(methyl methacrylate) and methyl 2-chloroacrylate/2,2,2-trichloroethyl methacrylate copolymers were studied. While polymers containing large dopants exhibited relatively high refractive indices, their Tg values were low, making these materials unsuitable for GI POF applications. Six dopants yielded polymers that exhibited higher Tg values than the conventionally used (diphenyl sulfide)-doped polymer. The dopant dibenzothiophene, in particular, yielded polymers with the highest refractive indexes and Tg values, and polymers containing (phenylthio)benzene dopants also performed well.
