Abstract

The invention discloses a method for producing a patterned flexible conductive graphene cloth. The method comprises the following steps: immersing a cloth fabric in a trichlorovinylsilane compound solution to make the cloth fabric hydrophobic; fixing a pattern template on the surface of the cloth fabric, and processing the patterned part of the cloth fabric through plasma treatment to make the patterned part hydrophilic; and removing the pattern template, forming a graphene oxide film on the surface of the patterned part of the fabric, performing heating reduction on the obtained cloth fabricin a reducing agent solution, and then carrying out water immersion, flushing and air drying to obtain the patterned flexible conductive graphene cloth. The production method has the advantages of simplicity in operation, low requirements on devices and technologies, high utilization rate of raw materials, low cost and realization of mass production; and the patterned conductive graphene cloth produced in the invention has a good flexibility and a high conductivity, and is expected to be used in the fields of flexible electronics, super capacitors and wearable sensing.
