Embodiment 1

[0030] Embodiment 1: a kind of graphene-based anti-icing / deicing integrated wrinkled film (FSGF) is realized through the following steps in the present embodiment:

[0031] Step 1, transfer the rGO (reduced graphene oxide) film to the biaxially stretched acrylic base film with a pre-strain of 400% by dry method;

[0032] Step 2, then release the base film along one uniaxial direction to make it shrink back, and then release the base film in another uniaxial direction to make it shrink back to its original size to obtain rGO wrinkled film;

[0033] Step 3: Add 30 mg of cetyltrimethylammonium bromide (CTAB) into the ammonia-water mixture, mix well, then put into step 2 to obtain rGO wrinkled film, stir magnetically for 6 hours under heating in a water bath at 40°C, and then gradually Add 1 mL of tetraethyl orthosilicate drop by drop, keep stirring for 12 hours after the dropwise addition, then take it out and dry it at 50°C;

Abstract

A graphene-based anti-icing / deicing integrated wrinkled film and a preparation method thereof belong to the technical field of real-time anti-icing / deicing in the air. The invention aims to solve the technical problem of difficulty in anti-icing and de-icing in extreme environments. The wrinkled film (FSGF) of the present invention is to transfer rGO to the biaxially stretched acrylic VHB 4910 base film by dry transfer first, and obtain the wrinkled rGO film through the retraction of the base film; then grow SiO on the rGO surface by the method 2 Nanoparticles, finally prepared by FDTS surface modification. The pleated film of the present invention still maintains anti-icing performance at a temperature of -20°C; at the same time, when the temperature is -20°C, it can completely deicing and defrosting at a low voltage in 30s, showing excellent anti-icing properties. Icing and deicing performance, has great application prospects in the field of real-time anti-icing / deicing in the air.

Description

technical field [0001] The invention belongs to the technical field of real-time anti-icing / deicing in the air; in particular, it relates to a preparation method of a novel graphene-based micro-nano hierarchical structure wrinkled film having both superhydrophobic performance and electrothermal performance. Background technique [0002] Large-scale ice accumulation on the surface of the aircraft will lead to frequent flight delays; ice accumulation on the wings will lead to increased flight resistance, unbalanced weight of the two wings, and even crashes; ice accumulation on the cockpit windshield will affect the pilot's vision and judgment. Ice accumulation not only brings inconvenience to passengers on the plane, but even threatens their lives. At the same time, a crash can also cause casualties or damage to people or buildings on land. [0003] At present, super-hydrophobic materials are considered to be the best choice in the field of anti-icing / de-icing. Through their o...
