dc.description.abstractPolyurethane (PU) nanocomposites incorporated with polydopamine treated carbon nanotubes (PDA-CNTs) were prepared by solution casting method via in-situ polymerization, achieving excellent CNTs dispersion in the PU matrix. It was observed that, with a loading of only 0.3 wt%, the tensile modulus and tensile strength were increased by 40% and 100% respectively. This reinforcement even exceeded the predicted modulus by Halpin–Tsai model. It indicates extremely enhanced interfacial interaction between the fillers and the matrix. More interestingly, it was found that the incorporation of PDA-CNTs caused a significant change in the degree of phase separation in the PU matrix leading to a unique network-like structure which is responsible for the unexpected reinforcement effect. This understanding combining with the synthetic approach should be useful for future design of PU/CNTs nanocomposites for wide range of applications.en_US
