Abstract: (706 Views)
In this paper, colloidal glasses of polymethyl methacrylate (PMMA) which contain polymeric microspheres with various diameters are synthesized. To do this, first, the monodisperse colloidal particles of PMMA with a diameter of 246 nm were prepared using the suspension polymerization method. Then, they were used as a primary polymer to make colloidal particles consisting of different sizes using the free emulsion polymerization method. The vertical deposition method, which is a method based on the self-assembly of microspheres, was used for the growth of colloidal glasses. Furthermore, the properties of polymeric microspheres were investigated using UV-Vis spectroscopy. Colloidal glasses similar to colloidal crystals can be applied as templates in colloidal lithography.
Keywords: Colloidal glasses, Free emulsion polymerization method, Polymeric microspheres, Suspension Polymerization, Vertical deposition method.
