There has been an increasing amount of interest in the design and preparation of new biomaterials that can be used in the fabrication of medical devices for artificial prostheses and implant applications. In this research, core-shell nano-structured poly (methyl methacrylate)-polystyrene (PMMA-PS) was prepared using a two-step semibatch microemulsion polymerization system with PMMA and PS as the core and shell respectively. The Gemini surfactant 12-3-12, i.e., trimethylene-1,3-bis(dodecyldimethylammonium bromide) was employed as the emulsifier. PMMA and PMMA-PS latex nanoparticles with a small particle diameter of 14.7 nm and 38.4 nm, respectively, have spherical morphology. The prepared core-shell PMMA-PS polymers have great potential to be used as functional materials for prosthesis and implant applications.
