At present, most of them are prepared by graft polymerization or using a binder; the grafting method is to graft functional polymers on the surface of existing polyolefin fibers, which often require harsh conditions such as anhydrous and oxygen-free; The binder method is to use a binder to directly combine the functional substance with the fiber, and there are problems such as the joint surface is not firm and affects the function of the functional substance.

Abstract
The invention discloses a polyolefin composite material with an intelligent surface, and a preparation method and application thereof. The polyolefin composite material comprises a polyolefin matrix and particles covering the polyolefin matrix, wherein the particles and the polyolefin matrix are chemically bonded; preferably, the particles are polymer particles; more preferably, the particles arepolymer particles with environmental response; thus, covering of the surface of the polyolefin matrix with the particles can improve the hydrophilicity and hydrophobicity of the material and endows the material with certain environmental response. The preparation method comprises the following steps: preparing the polyolefin matrix having reactive groups on the surface at first; then preparing theparticles having reactive functional groups; and finally, mixing the polyolefin matrix and the particles for a reaction so as to obtain the polyolefin composite material. The polyolefin composite material of the invention can be used for smart textiles, non-woven fabrics, porous films, waterproof gas-permeable membranes, battery diaphragms, composite materials, and switch films.
Description
technical field [0001] The invention belongs to the field of polymer materials, in particular to polyolefin materials, in particular to a polyolefin material with an intelligent surface and its preparation method and application. Background technique [0002] Polyolefin materials are widely used in all aspects of the national economy, among which polyolefin film materials are widely used in various fields such as batteries, barriers, catalysis and filter materials. However, traditional polypropylene films generally have smooth and uniform surface properties. The application is mainly determined by the nature of the polyolefin body. Changes in the hydrophilic and hydrophobic properties of polyolefin surface seriously affect its performance. [0003] In the prior art, the roughness is improved by surface etching, thereby improving the hydrophilicity and hydrophobicity of the surface. However, the etching will reduce the mechanical properties of the material to a certain exten...
