J. Hao et al. (China) report the influence of polyvinyl alcohol on the thermal conductivity and the fluidity (sol-gel transition behavior) of carbon nanotubes-glycerol nanofluids.
The thermal conductivity, stability, fluidity, and rheological properties were investigated by using various characterization techniques. The additional polyvinyl alcohol could amazingly reduce the viscosity of the nanofluids while the thermal conductivity was mostly maintained, even slightly further increased.
It suggests the as-prepared nanofluids may be applicable in energy transfer systems and thus pushes one step further towards real application of CNT based nanofluids.
