How to reduce the pollution of electronic products from electronic material sources is an urgent problem to be solved.
Currently, the most used conductive materials are aluminum foil, copper foil and copper beryllium alloy film. But their use in flexible electronics is limited due to their limited flexibility and fatigue resistance.

On the other hand, most of the polymer substrates used at present are non-degradable polymer materials, and new problems are caused by the treatment of waste electrons and environmental pollution. With the development of electronic products, higher requirements are put on electronic materials, and excellent flexibility, ductility, micro-nano structure controllability, stability in a flexible matrix and the like are required. The development of the novel green conductive composite material has important significance and market prospect.

The electrostatic spinning nanofiber membrane has the characteristics of small aperture, high porosity, adjustable micro-nano structure and adjustable mechanical property. The structure and properties of electrospun films can be controlled by a number of factors, such as: solution properties (viscosity, solvent, conductivity, and surface tension); control variables (static voltage in the infusion tube and needle, potential at the needle port, and distance between the needle port and the collector); environmental parameters (solution temperature, ambient temperature, air humidity).
The composite material has good degradability, good mechanical property and high conductivity. The conductive composite film with the adjustable and controllable microstructure has wide market application prospect in the fields of flexible electronics, flexible robots, flexible power supplies, wearable equipment, artificial skin, wound accessories and the like.
