Abstract

The invention relates to a method for manufacturing a composite material based on nano-particle three-dimensional micro-nano structured arrangement, which comprises the following steps of: placing micro-nano particles in mother liquor to obtain a solution containing micro particles; placing part of the solution in a container for leveling, applying a first structured field to the solution in a container, and controlling the particles in the solution to achieve controllable patterning arrangement of the particles in the solution; solidifying and molding the solution in the container, moving thecontainer downwards, supplementing the solution containing the micro particles in the container, changing structural field parameters to achieve the longitudinal controllable arrangement of the particles in the solution, and adopting different structural fields to achieve different patterning arrangements of the particles in the solution containing the micro particles; changing a first structuralfield into a second structural field so that the particles are arranged into corresponding shapes; repeating until the composite material with three-dimensional micro-nano structured arrangement of functional nanoparticles is obtained; the method has the advantages of directional localized adjustment, high efficiency, capability of achieving the forming of any three-dimensional shape structure and the like.

Description

technical field [0001] The invention belongs to the technical field of micro-nano manufacturing nanostructures, and in particular relates to a composite material manufacturing method based on three-dimensional micro-nano structured arrangement of micro-nano scale particles. Background technique [0002] The constrained spatial dimensions of nanostructures can be divided into four types: (1) zero-dimensional nanoatom clusters; (2) one-dimensional fibrous nanostructures whose length is significantly greater than their width, such as carbon nanotubes; (3) two-dimensional Layered nanostructures, the length and width dimensions are at least much larger than the thickness, and the grain size is nanoscale in one direction, such as graphene; (4) three-dimensional nanosolids, which have been prepared by various methods Different nanomaterials, and many preparation methods, according to whether the prepared medium is gas, liquid or solid, can be generally divided into three types: gas...

Problems solved by technology

Most of these methods realize the preparation of three-dimensional nano-solids by controlling the growth of nanoparticles. The distribution of nanoparticles in functional materials is mostly dispersed and unstructured, and it is impossible to realize the orientation of functional nanoparticles with three-dimensional micro-nano structure.
