Abstract

The invention discloses a super-hydrophobic polypropylene film and a preparation method thereof. The method comprises the following steps: firstly, weighing a definite amount of isotactic polypropylene granules and adding the granules into dimethyl benzene, rising the temperature to 130 DEG C, and stirring the solution by magnetic force to form 1 to 50mg / mL polypropylene solution; secondly, adding 20 to 60 percent of acetone by the volume of the solution into the polypropylene solution, and quickly stirring the solution; and finally, coating the polypropylene solution added with the acetone on a substrate by adopting a coating method, and drying the substrate for 3 to 12 hours at a temperature of between 20 and 70 DEG C to obtain a white film, namely the super-hydrophobic polypropylene film. The method has the advantages of simple operation, low cost and good controllability, does not need complex chemical treatment or expensive equipment, and is easy for industrialization. The obtained super-hydrophobic polypropylene film has the characteristics of better surface structure stability, weather-proof durability, chemical corrosion resistance and the like.

Description

technical field

[0001] The invention relates to the technical field of a superhydrophobic film material, in particular to a superhydrophobic polypropylene film and a preparation method thereof. Background technique

[0002] It is well known that the wettability of a material surface depends on the surface chemical properties of the material and the surface morphology of the material. The contact angle on a smooth surface can only be increased to 120° at most, but there are a large number of superhydrophobic surfaces in the natural environment (the contact angle between the material surface and water is greater than 150°, and the rolling angle is less than 10°), the most typical one is the superhydrophobic surface. Leaf surface self-cleaning effect. Superhydrophobic surfaces are of great significance in basic research and industrial applications due to their waterproof, anti-fog, self-cleaning and other characteristics, and have attracted extensive attention.
