Abstract Amine containing methacrylic based hyperbranched copolymers were prepared according to type II photoinitiation methodology in the presence of a commercially available photoinitiator. Several feed ratios of 2-(diethylamino)ethyl methacrylate and methyl methacrylate monomers were used to obtain copolymers with varying branching densities. Resulting copolymers were easily modified using pyrene functional compound via Menschutkin quaternization reaction. Subsequently, pyrene possessing hyperbranched copolymers were attached onto multiwalled carbon nanotube surface by π-π stacking strategy. Gel permeation chromatography, thermal gravimetric analysis and UV spectroscopy were utilized to analyze structures and molecular weight values of modified copolymers and precursors. Dispersion experiments of resulting copolymers/CNT were also carried out in organic and aqueous media in different pH values.
