Abstract

The invention relates to a preparation method of polymer particles with wrinkling surfaces. According to the preparation method, macromolecular poly(glycidyl methacrylate) with initiating activity andamphiphilicity is taken as a raw material, and without adding additional small molecular emulsifiers or initiators, a hydrophobic cross-linking monomer is initiated to polymerize, so that polymer particles having a surface wrinkling morphology are obtained. Compared with an existing preparation method for polymer particles with wrinkling surfaces, the method is simple in system and technology, simple for post-processing, high in universality, low in cost and suitable for industrial mass production. The prepared polymer particles have wide application prospects in the fields of optical devices, drug loading systems, self-cleaning coatings, cell adhesion, super-hydrophobic materials, electronic self-assembly templates and the like due to a relatively large surface area and morphological controllability.

Description

technical field [0001] The invention belongs to a method for preparing polymer materials, and relates to a method for preparing surface wrinkled polymer particles. Background technique [0002] Polymer particles with complex wrinkle circuits on the surface are widely used in optical devices, drug-loading systems, self-cleaning coatings, cell adhesion, superhydrophobic materials and electronic self-assembly due to their large specific surface area and shape controllability templates etc. At present, a series of methods are applied to the preparation of surface wrinkled polymers, mainly including microfluidic technology, ultraviolet radiation method and suspension polymerization method. [0003] In the above preparation methods, microfluidic technology focuses on the construction of microfluidic channel systems to realize the control and operation of fluids at microscopic scales. The devices required for microfluidic systems include micropumps, microvalves, micromixers, micro...
