摘要

Abstract

The focus of this work is to control the structure of electrosprayed polymer microspheres and then study the effect of different structures on the microspheres’ adsorption properties. Scanning electron microscopy (SEM) coupled with image analysis software was employed to evaluate the size distributions and the structure of microspheres. According to the observation and analysis results

two types of polyethersulfone (PES) porous microspheres (perfect sphere-shaped and collapsed) were prepared

via

electrospraying technology by adjusting the solvent and polymer molecular weight. The porous PES microspheres can remove bisphenol A (BPA) from its aqueous solution effectively. Compared with collapsed microspheres

the rough microspheres had much higher specific surface area and better mobility in the BPA aqueous solution

so it showed a better adsorption capacity than that of collapsed microspheres. The solvent evaporation rate and the occurrence rate of phase separation significantly affect the structure and morphology of microspheres.
