Styrene–acrylonitrile copolymer (SAN) and multi-walled carbon nanotube (CNT) nanocomposites were prepared by solution casting from aqueous solution. The composites were prepared with different CNT concentrations. CNTs significantly affected mechanical properties of the obtained materials. The elastic modulus and ultimate strength of the composite films were improved though ultimate elongation reduced by increasing the CNT content. Apart from studying stress–strain characteristics, some calorimetric investigations were carried out to explain the specific deformation behaviour from the structure viewpoint. Dielectric measurements indicated an increase in AC conductivity and dielectric permittivity already at a small CNT addition.
