abstract = {The tribological performance of novel bio-based lubricating greases thickened with electrospun
lignin nanostructures was investigated in a nanotribometer using a steel-steel ball-on-disc
configuration. The impact of electrospun nanofibrous network morphology on friction and wear
is explored in this work. Different lignin nanostructures were obtained with electrospinning using
ethylcellulose or PVP as co-spinning polymers and subsequently used as thickeners in castor oil at
concentrations of 10-30% wt. Friction and wear generally increased with thickener concentration.
However, friction and wear decreased when using homogeneous bead-free nanofiber mats (with
higher fiber diameter and lower porosity) rather than nanostructures dominated by the presence of
particles or beaded fibers, which was favored by reducing the lignin:co-spinning polymer ratio.},
