▎ 摘  要

NOVELTY - Preparing super-hydrophobic paper-based dual-function flexible sensing material comprises (i) beating the beating fiber, reinforcing agent and graphene dispersion to the papermaking requirements, where the mass ratio of the graphene and the reinforcing agent in the fiber and the graphene dispersion is (60-85):(15-40):(1-10) to obtain a mixed slurry, and (ii) preparing the mixed slurry into graphene paper, soaking in the papermaking sizing agent, and drying. USE - The material is useful in strain sensor and pressure sensor (claimed). ADVANTAGE - The material is environmentally friendly and economical, degradable, and easy to be processed. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for superhydrophobic paper-based bifunctional flexible sensing material obtained by the above mentioned method; and #use of sensing material in strain sensor with strain coefficient GF of 19.54, corresponding time of 0.3 seconds, where the bending of the human finger can be detected in a dripping environment and pressure sensor detect pressure of 0-1421 kPa, and response time of 0.48 seconds.
