Abstract

The invention provides a preparation method of a flexible high-strength textile-based conductive composite material. According to key points of the method, a cellulose nanocrystal (CNC) is used as a template, a conductive monomer is added in a low-temperature acid state, then persulfate is slowly added dropwise, a conductive polymer / CNC hybrid material is generated through in-situ oxidative polymerization, a metal salt solution is added dropwise, then a polyvinyl alcohol (PVA) solution is added, the mixture is stirred uniformly and poured into a culture dish where a textile fabric is spread, and the conductive composite material is obtained after natural air-drying. The material has both biocompatibility and the conductivity of the conductive polymer and also has self-healing performance and excellent mechanical properties and wearability of a textile matrix; and moreover, the material has excellent sensing performance and can perform human exercise monitoring, thereby having broad application prospects in the fields of strain sensors, intelligent robot sensing skin, flexible wearable electronic equipment and the like.

Description

technical field [0001] The invention relates to a preparation method of a conductive composite material, in particular to a preparation method of a flexible high-strength textile-based conductive composite material, and belongs to the field of conductive composite material preparation. Background technique [0002] With the needs of social development and the expansion of robot application fields, people's requirements for intelligent robots are also getting higher and higher. The environment in which intelligent robots live is often unknown and unpredictable. In the process of studying intelligent robots, technologies such as intelligent sensing are mainly involved. Sensing skin is a system that allows robots to have a "tactile sense". It can be attached to the surface of the device like clothes, allowing intelligent robots to perceive information such as the location of the object and the hardness of the object. Therefore, there is an urgent need for a sensing skin materi...
