Abstract

The invention discloses a preparation method of a copper hydroxide nanobelt oriented film. The method comprises the following steps: uniformly mixing 0.002-0.008 mol of cuprous nitrate trihydrate and5-15 mL of polyethylene glycol, performing dissolution, adding 1-5 g of sodium hydroxide particles, and performing a reaction for 2-10 h under stirring to form a blue suspension; performing washing for a plurality times by using distilled water and absolute ethanol to remove impurities, and performing dissolution in a high-purity ethanol solution to obtain a copper hydroxide precipitate; and injecting precursor solutions with different concentrations of 1-10 mol/mL into an aqueous solution at a speed of 100-1000 [mu]L/min to form an oriented film, transferring the oriented film onto a substrate, and performing drying in a vacuum drying oven at 40-60 DEG C. According to the preparation method provided by the invention, the copper hydroxide nanobelt oriented film prepared by the method has auniform surface, uniform arrangement of nanobelts and a higher orientation degree, and opens up novel possibilities for preparation methods of organic, inorganic and organic-inorganic hybrid orientedfilms.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a method for preparing a copper hydroxide nanobelt oriented film. Background technique [0002] In recent years, oriented thin film materials composed of organic, inorganic and organic-inorganic hybrid materials have been extensively studied. Due to their good physical and chemical properties, they can be used in many aspects such as separation of substances, electronics, optics and device equipment. Generally, organically oriented films can be obtained by methods such as mechanical shearing, solution pulling, and melt stretching, but there are certain defects. Mechanical shearing is not easy to prepare films with uniform surface and consistent orientation, and the instability of solution pulling makes The degree of orientation of the film is low, and it is difficult to prepare an organic oriented film with a high melting point and strong rigidity by melt ...
