Abstract

Method for preparing nanomaterial array system by porous alumina template nano mask method is constituted by following steps: (1) adopting the porous pellumina as templet of the mask and covering it on the base material; (2) forming nano granule array system on the base material by coating technique; (3) removing porous pellumina template to get nano granule array system; (4) processing a chemical reaction conversion in situ by the nano granule array prepared from step (1)(2)(3), further obtaining nano granule array system of the other materials. The produced nano material has an good controllability in dimension, orientation and position and a wide adjustable property (5-200 nano) of the diameter of the nano material. The invention can produce multifunctional nano granule, nano wire, nano tube or nano column array system and assembles nano material on a plurality of nano materials.

Description

(1) Technical field: [0001] The invention belongs to the fields of chemistry and chemical industry, in particular to a method for preparing a nanomaterial array system based on a porous alumina template nano-mask method. (two) background technology: [0002] At present, nanomaterials are widely used in various fields, and the birth of various nanodevices in the laboratory means that microelectronic devices will enter a new era—that is, quantum devices based on various quantum effects. Semiconductor nanomaterials (such as quantum dots, quantum wires, and superlattices) have attracted widespread interest due to their many exotic optical, electrical, sensitive, and catalytic properties. However, the fabrication of nanodevices is still a challenging topic. We know that deviceization of nanomaterials usually requires the ability to control the structure, dimension, size, position and orientation of the grown materials, and to assemble or integrate nanomaterial array systems with...
