Abstract

The invention relates to an elastic conductor. The elastic conductor is characterized by comprising an elastic base body and a conductor semi-continuously distributed in the elastic base body in the length direction, wherein the elastic base body comprises a surface base body and a core base body; the surface base body covers the core base body to form a surface layer; the conductor is semi-continuously distributed in the core base body to form a conductive path. The elastic conductor can be used under the condition of stretching; when stretched within a certain range, the resistance of the conductor is basically kept unchanged; the elastic conductor can be widely applied to the fields of earphone wires, folding cellphone screens, computer screens and the like.

Description

technical field [0001] The invention relates to an elastic wire, in particular to a stretchable elastic wire with high conductive efficiency and a preparation method thereof. Background technique [0002] There are many low-voltage wires in daily life, such as earphone cables, USB keyboard and mouse cables, and other low-current cables. In order to take into account the length requirements of daily use, these wires are often long cables that cannot be stretched. [0003] At the same time, the traditional conductive materials are all metal materials, such as silver, copper, aluminum, etc., and the wires used more in daily life are also copper wires. With the development of polymer composite materials, it has also been reported that conductive materials such as graphite and other conductive powders are added to the polymer materials for blending to prepare conductive materials with certain conductivity. However, such conductive composite materials have the defects of high res...
