Problems solved by technology

[0004] The prior art discloses a variety of methods for preparing such adhesive materials. For example, U.S. Patent US2008 / 0280137 discloses a method for preparing adhesive materials by using chemical deposition and catalytic methods to generate aligned carbon nanotubes on a substrate material , wherein the carbon nanotubes play the role of gecko foot setae, but the carbon nanotubes are not easy to arrange on the coplanar surface, resulting in irregular protrusions on the obtained adhesive material and poor adhesive performance, and this preparation method is relatively Complex, harsh preparation conditions, difficult to achieve industrial production
U.S. Patent US2010 / 0021647 discloses a bonding material made of polymer fibers prepared by nanoimprinting and template replication. The polymer fibers can form a protruding structure on the base material, but this method is cumbersome and requires the use of Micron-scale or even nano-scale templates are likely to cause problems such as structural overlap and structural defects in the adhesive material, reducing the adhesive performance and reusability of the material
U.S. Patent US2010 / 0086785 adopts a method of limited removal of polymer substrates to prepare a bonding material composed of polymer fibers. This method mainly uses solvent corrosion and dissolution of polymer fibers and part of the substrate to form protrusions. Not only the steps are cumbersome , and the controllability of the material structure is poor, and the adhesive performance of the obtained adhesive material is not ideal

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of an adhesive material. Background technique [0002] Geckos can stay motionless or walk easily on tree trunks, walls, ceilings, and even vertical smooth glass plates. This peculiar climbing and walking ability is mainly determined by the multi-level hierarchical structure on the gecko's feet. The study found that there are hundreds of protrusions on the gecko's feet, called flaps, and each flap has millions of bristles, and the end of each bristle is divided into hundreds of filaments with a diameter of only a few hundred nanometers. It is this unique structure that gives geckos their unique clinging and walking abilities. [0003] According to the structure and bonding principle of gecko feet, human beings have designed gecko bionic dry-type adhesive materials, which imitate the structure of gecko feet, and produce a large number of ...
