Abstract

The invention discloses a patterned polymer layered material, the patterned polymer layered material comprises at least three laminated structures, which are respectively a polymer substrate layer, a patterned structure layer and a surface encapsulation layer; the pattern The patterned structure layer has dispersed bowl-shaped protrusion structures, grooves or porous structures; the surface encapsulation layer is an encapsulation layer covering the surface of the patterned structure layer and retaining the shape of the patterned structure layer. The present invention provides a novel large-area convex bowl-shaped patterned structure with an unconventional porous structure, and also provides a composite material patterning technology based on a thermosetting polymer system and containing inorganic nanoparticles; Biomimetic generation on the material layer, combined with the raw material of the upper encapsulation layer, forms a stable encapsulation structure, and achieves the purpose of enhancing the performance of the patterned polymer material.

Description

Technical field[0001]The invention belongs to the technical field of material surface modification, and relates to a modified hydrophilic or hydrophobic layer surface structure, in particular to a polymer material with a large-area patterned design. The patterned polymer surface structure of the present invention has the characteristics of low cost and large area preparation, and has advantages compared with the existing patterned surface layered structure.Background technique[0002]The wettability of the material surface, such as hydrophilicity or hydrophobicity, can be adjusted and changed by adjusting the liquid contact angle through the unique structure of bionics design and the difference in hydrophilicity and hydrophobicity of the material itself. Different materials can achieve different surface wettability to meet the requirements of different engineering application environments. Although the hydrophilicity and hydrophobicity of the material itself can achieve the optimizati...
