Abstract

The invention discloses a method for manufacturing high-polymer material hydrophilic microtubes, which comprises the following steps: carrying out oxidization radiation on the surfaces of a high polymer material filter plate and a high polymer material cover plate by using oxygen plasma under the conditions of certain gas flow rate and pressure, directly bonding the filter plate and cover plate subjected to oxidization radiation at certain temperature under the action of certain contact force to form microtubes between the filter plate and cover plate, immersing the bonded high polymer material in a surfactant solution to perform treatment, and naturally drying the bonded high polymer material in a vacuum environment to obtain the high polymer material with hydrophilic microtubes. On the premise of ensuring the maximization of the hydrophilic modification effect, after the oxygen plasma is utilized to activate the material surface, bonding is directly performed to form the microtube device. The method does not change the characteristics of the material, and only improves the surface hydrophilicity of the high polymer material; and the method is simple to operate, and has the advantages of low cost and obvious effect.

Description

Technical field: [0001] The invention belongs to the field of modification of macromolecular materials, and in particular relates to a method for making hydrophilic micropipes of macromolecular materials. Background technique: [0002] Organic polymer materials have many excellent properties and are widely used in building materials, automobiles, medical, chemical and aviation industries. However, many polymer materials exhibit hydrophobic properties due to the non-polar surface. If it is necessary to perform adhesion and coating without surface treatment, the effect is very poor, or even impossible, so that in some applications, it needs to be modified. Taking PMMA as an example, its chemical name is polymethyl methacrylate, commonly known as acrylic or plexiglass, it is a polymer thermoplastic with good transparency, chemical stability and weather resistance, and it is widely used as a building material. , advertising materials, medical products, and the automotive indus...
