Abstract

The invention relates to the field of preparation of novel materials and in particular relates to a method for preparing a novel optical waveguide material. According to the technical scheme, the method comprises the following steps: dissolving fluorine-containing polycarbonate into cyclopentanone, and preparing into a solution with solid content of 55-65%; adding 1-5% of a photoinitiator, 0.5-1.0% of dodecyl mercaptan and 0.5-1.0% of hydroxyphenyl-S-triazine, uniformly stirring, coating on a mold, and standing at a temperature of 30-40 DEG C for 30-50 minutes; irradiating by an ultraviolet lamp for 10-15 minutes, thereby obtaining the novel optical waveguide material. The optical waveguide material prepared in the scheme has excellent solubility and machinable property, is excellent in comprehensive performance, good in stability and low in optical loss and has wide application prospects on optical waveguide devices.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a method for preparing an optical waveguide material. Background technique [0002] The geometric structure of the optical waveguide material can control the light inside or on the surface, and guide the light to propagate along the established path; as the demand increases, the requirements for long-distance optical transmission are getting higher and higher. [0003] CN100360584 provides a 2 +B 3 A method for synthesizing fluorine-containing hyperbranched optical waveguide materials by reaction of type monomers. With 1,3,5-tris[4-(4-fluorobenzoyl)phenoxy]benzene and (3-trifluoromethylbenzene)hydroquinone or (3,5-bistrifluoromethylbenzene) Hydroquinone or 6F-bisphenol A is used as the raw material; the raw material, salt forming agent, water-carrying agent and solvent are mixed according to the ratio and stirred with nitrogen, the temperature is raised to reflux to release...
