CNC in Lubricants (part 2)
We reported last year the value of Cellulose Nanocrystals (CNCs) in water-based lubricants. A new publication by Ke Li et al from the Wuhan University of Technology has shown that these results can be replicated in oil-based lubricants. Again, it was shown that, with only 2% CNCs, the coefficient of friction decreased by 30% compared to the control which in this case was a polyalphaolefin (PAO) base oil rather than water. These results were obtained with CNCs grafted with stearoyl chains, but some value was obtained with unmodified CNC. As shown in the images, the wear was decreased significantly.
