Problems solved by technology

However, there are deficiencies in both the two-dimensional ordered nanostructured metal material and its preparation method. First, the hollow metal spheres that constitute the two-dimensional ordered nanostructured metal material are only single-walled structures, rather than inner and outer walls. Hollow spheres with different structures, which limit its possible superior performance and unique uses; secondly, the preparation method cannot obtain hollow spheres with different structures on the inner and outer walls

Abstract

The present invention discloses an ordered structure array of two-dimensional hollow balls and a preparing method thereof. The array is a single-layer hollow ball array which is provided with an ordered hexagonal arrangement on a substrate. The outer diameter of each hollow ball in the single-layer hollow ball array is 220nm-10.8mu m. An outer surface of each ball is a rough surface. Each hollow ball is composed of a gold metal inner surface and metal gold or polypyrrole or zinc oxide which is coated on the gold metal inner surface. The rough surface is composed of particle-shaped objects or vertical rod-shaped objects. The method comprises the following steps: performing ion sputtering on a conductive substrate which is provided with a single-layer colloid crystal template for depositinga gold film and obtaining a gold film wall array; then placing the conductive substrate which is adhered with the gold film array into electrolyte; performing electrodeposition for 10s-3h with a deposition current density of -1.0-1.0Ma/cm2 for obtaining a complex array; then placing the complex array into a dichloromethane solvent for removing polystyrene colloid balls and preparing the ordered structure array of the two-dimensional hollow balls. The ordered structure array of the two-dimensional hollow balls can be widely used for the following fields: medicament engineering, cosmetic, biotechnology, photocatalysis, photonic device, etc.

Description

technical field [0001] The invention relates to a hollow sphere ordered structure array and a preparation method thereof, in particular to a two-dimensional hollow sphere ordered structure array and a preparation method thereof. Background technique [0002] Hollow sphere structures, such as carriers and inner containers, micro-reaction chambers, etc., have attracted widespread attention due to their special structure and surface properties, and they are of great importance in pharmaceutical engineering, cosmetics, biotechnology, photocatalysis and photonic devices. application value. The application of hollow spheres is related to its material type and structure size, and is also closely related to the fine structure of the spherical shell. Hierarchical hollow spheres, whose shells are composed of nanoscale small units, such as nanoparticles, nanorods and nanosheets, will play an important role in the construction of nanomaterial devices. Recently, the synthesis of hierar...
