Abstract
Carbon nanotubes (CNT) were functionalised with magnetite and compounded with polyurethane (PU). Two physical blending methods; melt-mixing and solvent dispersion, were used to prepare the compounds. Thermal stability, mechanical and thermal properties were characterised. Tensile properties, glass transition temperature (Tg) and magnetic properties increased with filler content. Filler concentration, processing technique and subsequent filler dispersion were factors that influenced material properties.
