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.
