Abstract :
Functionalized nanometer calcium carbonate (nanoCaCO3) particles were synthesized and used as emulsifier to stabilize High Internal Phase Emulsions (HIPEs). The porous polyacrylamide/CaCO3 (PAM/CaCO3) nanocomposite materials were prepared by CaCO3-stabilized HIPEs templates. The influence of the content of nano-CaCO3 particles on the stability of emulsions, and the morphology of the corresponding materials were all investigated. The photographs of HIPEs showed that the nano-CaCO3 particles with a contact angle O slight lower than 90° and appropriate content could effectively stabilize oil-in-water (o/w) emulsions. The scanning electron microscopy (SEM) images showed that the pores of the PAM/CaCO3 composites were close-cellular structure, and the average pore sizes were hundreds of micrometers in diameter.
