A new porous microsphere of Bisphenol A Epoxy Resin was obtained by drying in vacuum the waterborne system of Epoxy Resin previously prepared in our laboratory

and the morphology of the microspheres was observed by SEM.The preliminary results showed that the microsphere size is in the range of 5～20μm and the hole size is about 1μm

besides

the SEM result of the cracked microsphere could seemly give the more detailed information about the inner structure of the microspheres.
