▎ 摘　　要

NOVELTY - Oil sensitive and controllable precision deformed film comprises a polydimethylsiloxane cured film that is doped with graphene oxide, and the mass ratio of the graphene oxide to polydimethylsiloxane is 0.5-10%. One side of the film is a smooth surface, and the other side of the film is etched with a micro-track structure. The micro-track structure is multiple strip grooves, which are arranged in parallel manner. The longitudinal cross section of the strip groove is rectangular. The strip-shaped groove extends in the direction to be curled. USE - Oil sensitive and controllable precision deformed film. ADVANTAGE - The oil sensitive and controllable precision deformed film is convenient for production and processing, and reduces the problem of multi-layer structure life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing oil sensitive and controllable precision deformed film, which involves: (A) mixing and stirring graphene oxide and polydimethylsiloxane uniformly to obtain precursor body fluid; (B) pouring the precursor liquid on a smooth surface, using the mold to control the film thickness, and then degassing, heating and curing in a vacuum environment; (C) using laser etching to prepare the micro-track structure on one side of the cured film; and (D) cutting prepared film into the required shape to make oil sensitive and controllable precision deformed film.
