Embodiment Construction

[0016] In one embodiment, the present invention discloses a biomimetic special-shaped micro-nano composite structure manufacturing process based on 3D jet printing technology, the process includes:

[0017] (a) master patterning step, preparing microstructures on the single crystal silicon master by photolithography and deep dry etching process;

[0018] (b) a jet printing step, first performing a low surface energy treatment on the patterned substrate in step (a), then depositing a resin microlens array on the substrate through a jet printing process, and performing ultraviolet curing;

[0019] (c) Prepare the substrate step, coat the UV-curable resin on another substrate, select the same resin material as in step (b);

[0020] (d) transfer embossing step, the substrate obtained in step (c) is docked with the master plate treated in step (b) and transferred and imprinted, a certain pressure is applied, ultraviolet curing is carried out, and then the mold is demoulded, and the...

Abstract

The invention discloses a bionic irregular micro nano composite structure manufacturing process based on a 3D ejection printing technique. The bionic irregular micro nano composite structure manufacturing process comprises the following process steps: 1, patterning a mother set; 2, performing 3D ejection printing; 3, preparing a substrate; and 4, transferring and embossing. The bionic irregular micro nano composite structure manufacturing process can be used for manufacturing a micro nano composite structure of a gecko strip and has the advantages of high efficiency, low cost, large-scale manufacturing potential and the like.

Description

technical field [0001] The invention relates to 3D printing, in particular to a manufacturing process of a bionic special-shaped micro-nano composite structure based on 3D jet printing technology. Background technique [0002] Geckos can walk freely on smooth walls, and can stick upside down to the ceiling. This is because there is a special adhesive force between the gecko's feet and the surface of the interacting object, but the mechanism of this adhesive force has become a difficult mystery for centuries. [0003] Russell and Ruibal discovered through scanning electron microscopy that there are about 500,000 tiny setae growing on the bottom of each foot of the gecko, and the size of each setae is about 30-130 μm. American scientists Autumn et al. have found through experimental research that the micro-nano composite bristle structure and the contact surface molecules are very small, resulting in "Van der Waals force". Although the adhesive force produced by each setae i...
