Abstract
The invention discloses a preparation method of an ultra-thin Co(CO3)0.5(OH).0.11H2O nano film adhesive product. The method mainly comprises the following steps: adding excessive metal cobalt and carbonate to an alkaline solution of which the pH is greater than 10 at the stoichiometric ratio; and standing at a room temperature for over 10 days to prepare a supersaturated solution containing cobalt; mixing the supersaturated solution containing cobalt with deionized water at the volume ratio which is greater than 1 to 2, so as to obtain flocculent sediment; centrifuging or filtering and separating the obtained flocculent sediment to obtain the flocculent sediment and then washing the sediment; and firstly, washing and centrifuging or filtering and separating by using deionized water, ethyl alcohol, ethylene glycol or acetone, and then storing in an organic solvent. A fine structure of a Co(CO3)0.5(OH).0.11H2O product prepared by the method is an ultra-thin nanosheet structure; the product is high in purity, uniform in thickness, and high in superficial area; the preparation method is simple in process, mild in condition, easy to operate, low in production price, short in cycle, and suitable for industrial massive production.
