▎ 摘 要
NOVELTY - Optical fiber core composition comprises 0.1-10 pts. wt. of carbon nanotube graphene, and polymer including polymethylmethacrylate, polyimide, polycarbonate, polystyrene, polynorbornene and polyester in a ratio of 1-99:99-1. USE - The composition is useful for optical fiber core (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing optical fiber core composition, comprising mixing phosphoric acid solution or titanium dioxide solution and graphene solution in a ratio of 1:1, and adding polymer to the mixed solution and then drying.
