METHOD FOR INDUCING ORDERED ARRANGEMENT OF NANO-MICROSPHERES BY MEANS OF POLYMER CRYSTALLIZATION, AND USE THEREOF IN PREPARING COMPOSITE FILM

摘要

Disclosed is a method for inducing the ordered arrangement of nano-microspheres by means of polymer crystallization, and the use thereof in preparing a composite film. First, monodisperse PS-DVB nano-microspheres of different sizes are prepared by means of soap-free emulsion polymerization; the PS-DVB nano-microspheres prepared above are used as a raw material, and aqueous PEG solutions of different concentrations are added to induce the ordered arrangement of the nano-microspheres by means of solution-state PEG crystallization; and characterization is carried out using scanning electron microscopy and polarizing microscopy. The method is simple in terms of operation and is widely applicable. By further modifying the microspheres, the microspheres being in the ordered arrangement, the composite material can be applied to different fields. The replacement of a crystalline polymer substrate inducing the ordered arrangement of microspheres enables the nanocomposite material to become a thin film material modified and reinforced by the nano-microspheres, or a bulk material.
