Description

technical field [0001] The invention belongs to the field of laser processing and functional materials, in particular to a method for preparing graphene based on laser-induced polyether ether ketone. Background technique [0002] Graphene is a novel two-dimensional material with ultra-high specific surface area, charge mobility, electrical conductivity, and chemical stability. It is an ideal material for preparing micro-supercapacitors and sensor electrodes. At present, the use of graphene to prepare electrodes generally includes three steps. The first step is to prepare graphene oxide, which is easy to stack due to the strong van der Waals force and π-π bonds between graphene sheets, and has oxygen-containing functional groups. Graphene oxide can exist stably in aqueous solution, so strong oxidants are often used to chemically oxidize and strip natural graphite powder, and obtain graphene oxide solution under the physical assistance of ultrasound or centrifugation; the seco...

Problems solved by technology

[0003] The problem with the above method is that the preparation steps are complicated, the strong reducing agent and high temperature used to reduce graphene oxide will damage the substrate, and graphene is easy to fall off from the substrate

At the same time, since micro-supercapacitors are mostly used in wearable electronic devices, the biocompatibility of the above materials cannot meet the application requirements.
