Abstract
The invention relates to a method for preparing a super-hydrophobic NH4V4O14 nano-belt film, which comprises the following steps of: (1) mixing ammonium metavanadate NH4VO3 and ionized water according to a molar ratio of 1:1,000-1,500, dropwise adding acetic acid under the condition of magnetic stirring, reacting under the hydrothermal condition at the temperature of between 180 and 210 DEG C for 24 to 48 hours, and cooling a reaction kettle to the room temperature; (2) putting the products into a water- or ethanol-containing vessel, ultrasonically uniformly dispersing, removing the water or the ethanol at the temperature of between 40 and 80 DEG C, allowing a nano-belt to self-assemble in the vessel into a film with the thickness of between 40 and 100 mu m; and (3) depositing a thin layer of dimethyl silicon oil on the film through a thermal evaporation method, and transforming the surface of the film from hydrophilic to super-hydrophobic. A NH4V4O14 nano-belt film selective absorbing material can be prepared by a simple experimental apparatus through the method; and the method has the advantages of environmental protection, readily available raw materials, low toxicity and low price, and is a novel method for purifying the environment.
