Problems solved by technology

[0005] However, polymethyl methacrylate itself also has some shortcomings, such as a narrow temperature range; heat resistance, chemical corrosion resistance, and aging resistance are relatively poor; at the same time, polymethyl methacrylate has a certain brittleness. , which limits its application in certain fields
[0006] Methyl methacrylate homopolymerized polymer is used as the core material of plastic optical fiber. Plastic optical fiber has problems such as large attenuation, small bandwidth, and poor aging resistance, which restricts the large-scale application of plastic optical fiber in the communication field to a certain extent.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a plastic optical fiber core layer material and a preparation method and application thereof. Background technique [0002] Plastic optical fiber is a very important category in the field of optical fiber, and its research and development history has reached more than 30 years. The reason why plastic optical fiber has been actively developed by many countries and organizations in the world is that compared with silica optical fiber, plastic optical fiber has the advantages of large diameter, low density, good flexibility, easy processing, high coupling efficiency, and radiation resistance, and can be widely used. connection to the communication network. In the future, plastic optical fiber will be used as the main transmission medium for short-distance high-speed communication networks. [0003] The plastic optical fiber is composed of two materials, the core materi...
