Dataset of the article: Tunable structuring of nanocellulose-based sustainable lubricants by 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 mnanocellulose 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. Electro-rheological measurements were carried out in an ARES G2 controlled rate rheometer (TA Instruments, USA), equipped with a special electrorheocell, a Keysight 33210A electric field generator (Agilent, USA) and a Trek 609E-6 high-voltage power amplifier (Trek Inc., USA). Optical analysis was carried out using a portable optical microscope. More info: https://doi.org/10.1016/j.jmrt.2024.12.183
