It is led from the University of Huelva, and mainly developed at Center for Research in Chemical Products and Process Technology (Pro2TecS). Main objectives: generating scientific and technical knowledge that will advance the innovative concept of intelligent lubrication control using sustainable electrorheological fluids; developing a new generation of electroactive biolubricants that allow instant, on-demand control of their rheological and tribological properties through the action of an external electric field.This research examines sustainable nanocellulose-based lubricants made by dispersing fibrillated and crystalline nanocelluloses in castor oil. The study explores how electric fields and shear forces affect their rheological behavior and microstructure, using advanced microscopy and rheometry techniques. Findings show that lower nanocellulose concentrations form flexible string-like structures responsive to electric fields, while higher concentrations create rigid, entangled networks. Pre-shear intensity influences structural changes, altering the lubricants' mechanical properties under different electric fields.engNanocelluloseLubricantElectrorheologyOscillatory shearOptical microscopy analysisdataset10.33776/ariasmontano.27245open access3303 Ingeniería y Tecnología QuímicasOpen Data Commons Attribution License (ODC-By)
