  Novel nanocomposites based on polyurethane/carbon nanotube and incorporation of functional groups (hydroquinone and citric acid) were prepared by “solution casting method”. In this work, a high percentage of carbon-nanotubes (CNTs) was introduced successfully into the polyurethane. The samples were characterized by scanning electron microscopy (SEM); the results obtained showed a high dispersion of CNTs on polymer. Then, the thermal stability of the nanocomposites was evaluated by thermal gravimetric analysis (TGA), and the mechanical properties were evaluated by tensile test. Compared to pure polyurethane, the nanocomposites, with high loading of CNTs, displayed better thermal stability and mechanical properties (high elongation at break-1000%)... Read More»
