Problems solved by technology

The difference in heat resistance and environmental stress determined by the material itself makes the reliability of POF low
In addition, POF has poor heat resistance and high water absorption. When used in places with high ambient temperature or high humidity, there are serious problems such as large signal attenuation and easy aging, which limits its scope of application.

Abstract

The invention relates to the field of optical fiber materials, in particular to a plastic optical fiber with a modified nanometer material and a manufacturing method of the plastic optical fiber withthe modified nanometer material. The plastic optical fiber with the modified nanometer material comprises a core layer and a skin layer. The skin layer is arranged on the periphery of the core layer.The core layer material is made of modified polymethyl methacrylate. The skin layer material is made of modified polyethylene terephthalate. The plastic optical fiber with the modified nanometer material and the manufacturing method of the plastic optical fiber with the modified nanometer material solve the serious problems that a POF is poor in heat resistance and high in water absorption rate, and when the POF is used on the occasions with the high environment temperature or humidity, signal attenuation is high, and the POF is prone to aging. The manufactured plastic optical fiber has the advantages of being high in wear resistance, relatively excellent in heat insulation and hydrophobicity and lower in cost, being suitable for serving as a communication optical fiber and being particularly suitable for short-range light transmission materials such as decoration fabric.

Description

technical field [0001] The invention relates to the field of optical fiber materials, in particular to a nanomaterial-modified plastic optical fiber and a preparation method thereof. Background technique [0002] Plastic optical fiber, referred to as POF, has experienced more than 50 years of development since it was first used. Plastic optical fiber (POF) has the advantages of large elastic limit, large elastic deformation, high fracture toughness, convenient processing, simple operation and low cost. Parameter measurement in engineering, biomedicine and other fields. [0003] However, during the communication process, the ambient temperature has a great influence on the POF performance. Since POF is made of polymer, it can work at a temperature of 80-100°C. Beyond this range, the POF starts to lose its robustness and light transmission. The poor thermal environmental stress determined by the material itself makes the reliability of POF low. In addition, POF has poor h...
