The flexible base has electric conductivity and thermal conductivity and insulation, can be adapted to improvement of the environmental temperature of the flexible hose, ensures that the liquid metal is in the fusion state, and meets the requirements for high conductivity of the flexible conductor, especially for use in areas at lower environmental temperature. The flexible conductor wire is easy to process and mold, satisfies conductance demands in intelligent dresses, prevents generation of bubbles by spraying and printing of the liquid metal and the wrapping glue material in the laminated alternative way, and ensures the stability of conductance.

Description

technical field [0001] The invention relates to a flexible conductive wire body and a forming process thereof, and belongs to the technical field of forming linear conductors on flexible substrates. Background technique [0002] Flexible conductor is a kind of conductor with the function of curling and bending. It is suitable for the field of clothing and used as smart clothing to meet various conductive needs. [0003] Traditional clothing conducts electricity with external conductive wires, which are exposed outside and affect the appearance of clothing. The conductive wires are traditional wrapped metal wires. During the wearing process, the solid metal wires in the conductive wires are easily bent and broken, resulting in open circuits. [0004] There are also metal-plated conductive wires in the prior art. The Chinese invention patent of CN109291593 discloses a textile-based washable conductive material, which is directly woven into clothing and plays a conductive role....

Problems solved by technology

[0007] Encapsulation of liquid metal can ensure the electrical conductivity and meet the function of anti-bending fatigue. However, it has certain defects. The melting point of liquid metal is different, generally above 20°C, and the melting point of special alloys can be controlled above 6°C. When the ambient temperature is lower than its melting point, it is easy to break the circuit in the cold shrinkage state, and it is difficult to ensure its conductive stability. In addition, air bubbles are easily generated during the filling process, which will affect the conductivity
