Abstract
This paper described the preparation of optically active polyurethanes (BPUs)/multiwalled carbon nanotubes (MWCNTs) composites through the high-intensity ultrasound. SEM and TEM observations showed the homogeneous coating of MWCNTs by BPU. The infrared emissivity (8-14μm) study revealed that the composites possessed much lower infrared values compared with those of the polyurethanes and nanotubes, due to the special interface effect. The lowest infrared emissivity values of nanocomposites were S-BPU/MWCNTs εmin=0.461 and R-BPU/MWCNTs εmin=0.418, respectively.
