Resumo: Conducting polymer composites are increasingly investigated for the development of piezoresistive materials for sensor applications due to their outstanding electromechanical properties. In this work, the effect of different surfactants on the piezoresistive response of triblock copolymer styrene-butadiene-styrene (SBS)/carbon nanotubes (CNT) composites was studied. Surfactants act as dispersing agents for CNT decreasing the size of agglomerates. The use of different surfactants such as Triton-X100 (TX-100), cetyltrimethylammonium bromide (CTAB) and sodium dodecylbenzenesulfonate (SDBS) affects the percolation threshold as well as the mechanical and piezoresistive properties of the composites. TX-100 decreases the mechanical response and electrical conductivity of the polymer composites, leading also to low piezoresistive response. CTAB and SDBS decrease the size of the agglomerates while maintaining their electrical conductivity up to 4 wt% CNT. Moreover, these composites present improved piezoresistive response with GF values up to 3 and deformations up to 10%, similar to the behaviour of commercial sensors with improved filler dispersion within SEBS polymer and promoting the use of novel range of printable methods.
