Abstract

This study engineers a self-assembled, sustainable lubricant material from plant-based protofilaments and a biopolymeric hydrogel. This material exhibits superlubricity with friction coefficients of 0.004–0.00007 under moderate-to-high contact pressures. Multiscale measurements and simulations reveal a synergistic mechanism where protofilaments anchor to the surface via hydrophobic interactions, while the hydrogel provides hydration lubrication. This platform offers potential for sustainable lubricants in diverse applications.
