Abstract

The invention relates to the technical field of high-molecular material processing and specifically relates to a preparation method of a super-hydrophobic polyethylene fiber film. The method comprises following steps: preparing ultrahigh molecular weight polyethylene spinning solution having a mass concentration of 0.1 to 0.5%; at 105 to 115 DEG C and the stirring speed being larger than 600 r/min, using a steel wire frame to rotate a crystal to spin and spin films, wherein the diameter of the steel wire is 0.5 to 1mm and the length and width of the steel wire frame are 40mm and 17mm respectively; then drying. According to the method of the invention, UHMWPE super-hydrophobic polyethylene fiber film having the shish-kebab structure can be directly manufactured by means of a flow induced crystallization method and the UHMWPE super-hydrophobic polyethylene fiber film has the function of self cleaning and can perfectly imitate the self cleaning capability of lotus leaf surface ; the film has the function of oil water separation and can absorb oil on the surface of water and can be applied in preventing sea pollution. The operation method of the invention is simple and convenient; the method is low in cost and has short period and is suitable for the industrialized popularization.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to a preparation method of a superhydrophobic polyethylene fiber film. Background technique [0002] Superhydrophobic surfaces have attracted research due to their properties of static contact angles greater than 150° and rolling angles less than 10°. In nature, many plant leaves and waterfowl feathers are superhydrophobic. The surface of these animals and plants generally secretes hydrophobic oil or wax, and the surface is very rough, and the contact angle with water can reach more than 150°. The lotus leaf is famous for its superhydrophobicity and self-cleaning, thanks to its special graded roughness: there is a layer of waxy nanostructure on the fine micro papillae structure, and the droplets will sit on the top of the papillae structure, so These leaves will exhibit excellent superhydrophobicity. At present, referring to the hydrophobic principle of natura...
