Abstract

The invention discloses a composite fiber with an intelligent surface and a preparation method and application of the composite fiber. The composite fiber comprises a fiber matrix and conductive particles covering the fiber matrix, and the surface of the fiber matrix covered with the conductive particles can improve the specific conductance of the fiber and further improve the electrical conductivity of the fiber. The preparation method comprises the following steps: firstly obtaining a fiber matrix with reactive groups on the surface, then obtaining conductive particles with reactive functional groups, and finally mixing the fiber matrix with the conductive particles for reaction to obtain the composite fiber. The composite fiber can be used for conductive fibers, antistatic fibers or fabrics, electronic circuits, sensors, smart textiles and the like, and is preferably used for conductive fibers and sensing and antistatic fiber fabrics.

Description

technical field [0001] The invention belongs to the field of fiber materials, and in particular relates to a composite fiber with an intelligent surface and a preparation method and application thereof. Background technique [0002] Fibers are natural or synthetic filamentous material fibers. Fiber materials are widely used in various fields such as fabrics, filter materials, and catalysis. However, the traditional fibers have single performance and cannot well meet some applications in the current society. The conductivity of the fiber matrix can be enhanced by combining the conductive particles with the fiber matrix. [0003] In the prior art, conductive devices are mainly used to increase the conductivity of the fiber matrix. However, the conductive devices and fibers do not achieve mutual integration in the microscopic sense, but only cooperate with each other in the macroscopic sense through simple physical methods. And there are a series of problems such as uncomfort...
