Thermal conductivity enhancement of nanofluids is very attractive to thermal and heat transfer engineering, however its mechanism is not clear yet. In this study, it is proposed that the surface charge state of nanoparticles is to explain the thermal conductivity enhancement of nanofluids. By comparing to the previous reported results, it is shown that the interparticle interaction due to the surface charge state is the most important factor to increase of thermal conductivity of nanofluids.
