Problems solved by technology

However, these two methods require extremely harsh conditions such as high temperature, high pressure or high vacuum, which have a very negative impact on the cost and efficiency of material preparation, so they need to be improved or replaced.
Another shortcoming is that the zinc oxide nanotube materials prepared at present are powdery and randomly dispersed, so there is still a certain distance for the application of nano-devices.

Abstract

The preparation process of nanotube oriented nano zinc oxide material includes dissolving zinc salt, ammonia water, thiourea and ammonium salt in certain proportion in deionized water to prepare film growing reaction solution; and soaking processed substrate inside the reaction solution, ultrasonic treatment for 35-40 min, heating to 94-97 deg.c to reaction for 45-60 min to obtain compact nanotube oriented nano zinc oxide material. The said process of the present invention is simple, low in cost and short in production period, and the prepared nano zinc oxide material consists of oriented nanotube of average diameter of 500 nm, thickness of 100 nm and length of 6 micron.

Description

technical field [0001] The invention relates to a preparation method of a zinc oxide nanometer material, in particular to a preparation method of a zinc oxide nanometer material with oriented arrangement of nanotubes. The zinc oxide nanomaterial with oriented arrangement of nanotubes is prepared by a chemical solution growth method. Background technique [0002] The structure and morphology of nanomaterials have a great influence on the performance and application of nanomaterials. The preparation of nanocrystalline materials with specific structures and morphologies is of great significance for the development of new fields of nanomaterial functions. Among the numerous shapes of nanomaterials (nanospheres, nanorods, nanowires, nanobelts, nanofibers, and nanotubes), nanotubes have become the focus of research because of their unique structures. Since the advent of carbon nanotubes in 1991, a large number of simple substances (silicon, germanium, copper, antimony, etc.) and c...
