[0035]The present invention provides a method for preparing a super-hydrophobic conductive multifunctional fabric surface, which comprises the following steps:
[0036](1) Constructing PDA / rGO surface by multiple dipping method
[0037](2) Growing copper nanoparticles in situ
[0038](3) Stearic acid modification
[0039]In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with specific embodiments.
[0040]Step 1: Preparation of PDA / rGO surface by multiple dipping method
[0041]In an embodiment, this step can be specifically performed as follows: First, cut 3 pieces of cotton cloth according to the size of 2×4 cm, and place them in a beaker to undergo sonication of acetone, absolute ethanol, and ionized water for 30 minutes. Dry it in an oven at 60°C and cool it for later use. Dissolve 2 mg / ml dopamine and 0.05 g sodium periodate in the tris solution, th...

[0055]In this embodiment, a super-hydrophobic conductive multifunctional fabric surface is prepared according to the following steps:
[0056]Step 1: Preparation of PDA / rGO surface by multiple dipping method
[0057]Cut 3 pieces of cotton cloth according to the size of 2×4 cm, and place them in a beaker through acetone, absolute ethanol, and deionized water for 30 min. After the sonication is completed, they are placed in an oven at 60℃ to dry and cool for use. Weigh 0.2 g dopamine and 0.05 g sodium periodate with an electronic balance, dissolve them in 100 ml Tris-HCI, stir for 0.5 h, add 2 mg / ml 100 ml graphene oxide solution, and stir evenly under the action of a magnetic rotor , And then add a clean cotton cloth, immerse three times, each immersion time is 0.5 h, the drying temperature is 80 ℃, after the reaction is completed, use deionized water to thoroughly clean the excess reactants on the surface of the cotton fabric.
