Study on Thermal Property of Nano-Carbon Tube/Polyurethane Nano-composites

Polymer-carbon nanotubes (CNTs) nanocomposites have attracted much attention of researchers since the discovery of CNTs in 1991 by Iijima[1]. CNTs have excellent mechanicalstrength, electrical and thermal conductivity and thermal stability [2-3], which is considered to be the most promisingreinforcing and functional fillers for polymer materials. Polyurethanes on the other hand is one of the most versatile materials today and is widely used in different applications[4]. Modification of polyurethane is mainly focused on its mechanical properties and thermal stability by two mainapproaches: the first is to change the molecular structure of polyurethane by modification of its raw materials and the second is to introduce the filler into the polyurethane matrix.Carbon nanotubes (CNT) are ideal reinforcing filler for composites because of their high aspect ratio, excellentmechanical strength, electrical and thermal conductivity and thermal stability. Thermal property of PU–CNT nanocomposites is considered in this study
