Embodiment Construction
[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The experimental methods for which specific conditions are not indicated in the examples are usually in accordance with conventional conditions or in accordance with the conditions suggested by the manufacturer.
[0027] The preparation steps of the wind speed tester based on graphene materials are as follows:
[0028] Step 1: Preparation of graphene film and PDMS bilayer structure
[0029] First, the substrate copper foil was placed in acetone, 95 vol% ethanol, and pure water for ultrasonic cleaning for 2 min each, dried with nitrogen, and then placed in the vacuum chamber of a tubular CVD system to prepare graphene to obtain a graphene film. like figure 1 As shown, 1 is a CVD tube furnace, 2 is a gas reaction chamber, 3 is a graphene material, 4 is a growth substrate, and 5 is a mechanical pump. A layer of PDMS with a thickness of 50um w...
