Silica-coated polymeric particles were synthesized based on cationic colloidal particles which were prepared by precipitation polymerization of divinylbenzene in the presence of a cationic monomer, N-[3-(dimethylamino)propyl]methacrylamide. Negatively charged silica precursors were interacted with the cationic charged dimethylamine groups in colloidal particles. The resulting polymer/silica core/shell particles were characterized by scanning electron microscopy (SEM). Moreover, omniphobic particles were achieved by coupling reaction of the core/shell particles with nonafluorohexyltriethoxysilane. Their water/oil static contact angles were investigated.
Journal for Nanoscience and Nanotechnology (JNN) is an international and multidisciplinary peer-reviewed journal with a wide-ranging coverage, consolidating research activities in all areas of nanoscience and nanotechnology into a single and unique reference source. JNN is the first cross-disciplinary journal to publish original full research articles, rapid communications of important new scientific and technological findings, timely state-of-the-art reviews with author's photo and short biography, and current research news encompassing the fundamental and applied research in all disciplines of science, engineering and medicine.
