Fabrication of Microporous PVDF Particles by an Emulsion Method and Control of Pore Structure

摘要

The microporous Poly(vinylidene fluoride) (PVDF) materials were prepared by emulsion in the article, and through appropriate methods to characterize considerable specific surface area and excellent pore structure. With DMF as solvent, ethanol as a diluents to dissolve and dilute PVDF, by virtue of this method to destroy the morphology of PVDF structure, that changed the spherical structure to porous structure, and to get the different pore size and specific surface area through controlling the speed of dripping water. The structure information, surface morphology and specific surface area were determined by XRD, SEM (or field emission) and specific surface area and pore size analyzer, then found the regulation about control of pore size and specific surface area preliminary.
