Problems solved by technology

The conductive coatings in the prior art use metal oxides as conductive agents, and are made with resins, additives and solvents, but on the one hand, they have poor toughness and flexibility, and do not have elasticity; on the other hand, they have high resistivity and poor electrical conductivity.
The resin molecules in common conductive films are mostly linear or cross-linked polymer structures, which have low elasticity, and cross-linked polymers do not have hot-melt properties, so they are not suitable for applications with high tensile deformation requirements , which also limits its application in complex manufacturing processes
