EG-water based MCNT nano-suspensions were prepared by two-step method. Both experimental work and theoretical analysis were carried out to investigate the rheological property of prepared samples at different volume fraction and temperatures. The results showed that the experimental viscosity value could be matched well with the modified K-D model considering effective volume fraction of aggregations. In addition, this work exhibited an interesting trend of the behaviour of the viscosity vs shear rate curve when temperature is dropping down. A particle aggregation transformation mechanism were proposed to reveal the relationship between MCNT aggregation conditions and temperature, furthermore to explain the variety of shear behaviour of nano-suspensions.
