Problems solved by technology

However, super-slippery surfaces are generally based on hard templates. At present, there is no method to integrate super-slippery surfaces into soft insect robots. However, insect robots with super-slippery surfaces are useful in anti-icing, anti-fouling, liquid transportation, etc. The field has important research significance

Abstract

The invention discloses an insect robot with an ultra-smooth surface, a processing method and application, and belongs to the technical field of insect robots. The insect robot has a profiling structure, and is oxidized by a graphene oxide layer and reduced graphene sequentially from bottom to top The reduced graphene oxide layer is a porous structure, which is obtained by laser processing the graphene oxide film; the surface of the reduced graphene oxide layer is filled with lubricating oil, and the lubricating oil penetrates into the reduced graphene oxide layer. in the hole. A large number of oxygen-containing functional groups contained in graphene oxide will react with CO 2 and other forms of gas escape to obtain a reduced graphene oxide layer with a large number of porous structures; and due to the limitation of the laser processing depth, the bottom of the graphene oxide film will not be recovered by the laser. Then, lubricating oil is injected into the reduced graphene oxide layer with a porous structure to become an ultra-slippery surface; an insect robot with an ultra-slippery surface is obtained by tailoring, which can realize anisotropic liquid transport.

Description

technical field [0001] The invention belongs to the technical field of insect robots, and in particular relates to using a laser to process a graphene oxide film to prepare a porous structure to obtain a substrate that can be used to prepare an ultra-smooth surface, and then pouring lubricating oil onto the substrate to form a super-smooth surface Insect robots, realizing the integration of the humidity-responsive properties of insect robots and the liquid transport properties of ultra-slippery surfaces. Background technique [0002] Insect robots are an important part of the current bionic robot field. Insect robots have the advantages of small size, light weight, simple structure, and fast walking speed. However, the traditional driving methods of hardware insect robots, such as electric and hydraulic actuators, coordinate with a large number of rigid links and joints, resulting in heavy and complex mechanical systems. . Therefore, the use of flexible smart responsive ma...
