Abstract
The work describes the synthesis of a hybrid material starting from surface-modified colloidal particles of styrene (ST)-acrylic acid (AA) copolymer and carbon nanotubes (CNTs). Vinyl double bonds have been chemically grafted on the surface of the ST-AA copolymer particles in order to be able to copolymerize with acrylamide (AM). The hybrid material was obtained by reaction between the free radicals resulted from both copolymerization and AM homopolymerization and the superficial groups of modified CNTs. Due to the difference between the diameter of the polymer particles and the one of the CNTs, a change in the CNTs shape is to be expected (disentanglement due to steric effects). The products thus obtained have been characterized using IR, SEM, XPS, Raman, and AFM techniques.
