Polystyrene-coated micro-sized particles by “in situ” surface initiated polymerization in accord with Langmuir model adsorption

► Adsorption of polystyrene chains “in situ” growth from micro-sized flat silicate particles was studied. ► A radical initiator was pre-adsorbed onto the inorganic surface. ► The adsorption isotherms were obtained from TGA and SEC data obtained during the direct polymerization. ► PS monolayer coverage increases with polymerization time and dependents on the monomer diffusion.
