Plastic optical fiber with fluorizated packet-layer and its prepn. method

Abstract

This invention provides a fluorate clad plastic fiber characterizing in having fluorate clad a fibre core or plastic fiber. This invention also provides the process method for fluorate clad plastic fiber including preparing materials: preparing fibre core or plastic fibre; putting fibre core or plastic fibre into a fluorate over with the concentration of 0.01%-10% to perform fluorate reaction for 2-72h at 10-80 deg.c to finish the fluorate clad plastic fiber.

Description

Technical field: [0001] The invention belongs to the field of multimedia information transmission materials for information communication and the field of advertising lighting, and relates to a novel plastic optical fiber product and a manufacturing method thereof that form a cladding through direct fluorination of the surface. Background technique: [0002] Plastic optical fiber (POF), also known as polymer optical fiber and polymer optical fiber, is composed of a transparent polymer core with a high refractive index and a transparent polymer cladding with a low refractive index. There are mainly step type (SI POF) and Gradient plastic optical fiber (GI POF), such as figure 1 , figure 2 . Due to the advantages of large diameter, good flexibility, low density, low loss window in the visible light region, and low cost and processing costs, plastic optical fiber has gradually been widely used in the fields of lighting, decoration, sensors, local area networks, and automotiv...

AI Technical Summary

Problems solved by technology

The first method has complex production process and high equipment requirements; in the co-extrusion process, the extrusion processing temperature of the core layer and the cladding material needs to be similar, and at the same time, it is easy to contaminate the optical fiber material and generate bubbles, interface defects, etc., resulting in increased optical fiber loss. Large; especially high-transparency fluororesin with similar processing temperature to PMMA has few varieties and high price, which limits the popularization and use of plastic optical fiber

The second method, although the production process is simple, is more likely to contaminate the fiber material and generate bubbles, interface defects, etc., resulting in increased fiber loss, making it difficult to manufacture low-loss fibers
