▎ 摘  要

NOVELTY - Preparing a composite membrane involves providing a graphene oxide-containing dispersion liquid and a polymer-containing solution, and electrospinning the solution while electrostatically spraying the dispersion to collect the prefabricated film at the same location. The prefabricated membrane includes a nanofiber membrane and an aggregate that is embedded in the nanofiber membrane, where the material of the nanofiber membrane is a polymer. The material of the aggregate is graphene oxide. The graphene oxide is reduced to obtain a composite membrane. USE - Method for preparing a composite membrane for pressure sensor (claimed). ADVANTAGE - The method enables to prepare a composite membrane with excellent flexibility and mechanical stability, and where the composite membrane ensures the high sensitivity, wide range and stable performance of the pressure sensor.
