Abstract

The present invention provides a method for preparing B phase vanadium dioxide nano rod by means of rheological phase reaction and self-assembly process combination, and is characterized by that said method includes the following steps: mixing inorganic vanadium oxide powder and cationic surfactant according to the mole ratio of 2:1, magnetic stirring for 1 hr. in absolute ethyl alcohol medium, adding proper quantity of deionized water, stirring and ageing for 48 hr to form rheological product, moving it into the stainless reactor still with teflon lining bottom, making hydrothermal reaction for 6-8 days at 180 deg.C, water-washing and filtering for 3 times, drying for 12 hr at 80 deg.C so as to obtain B phasek vanadium dioxide nano rod product with high surface activity.

Description

technical field [0001] The invention relates to a new method for synthesizing vanadium dioxide nanorods by combining rheological phase reaction and self-assembly technology, which belongs to the field of nanomaterials and nanotechnology. Background technique [0002] In recent years, one-dimensional nanomaterials have shown promising application prospects in optics, electrochemistry, electromagnetism, nanoelectronics, biomedicine and other fields, and have become the frontier research field of nanotechnology. At the same time, as one of the basic building blocks of nanodevices, one-dimensional nanomaterials have also attracted widespread interest from scientific and technological workers, but there has been no report on the synthesis of vanadium dioxide nanorods through the combination of rheological phase reaction and self-assembly technology. Contents of the invention [0003] The problem to be solved by the present invention is to provide a vanadium dioxide nanorod with...
