Description
Davis Kipkania Kiboi and six co-authors characterized a family of green lubricant candidates in a 2026 paper. Their liquids pair choline with amino acids, forming salts that stay liquid and cling to surfaces. Ten variants were made, spanning simple, branched, multifunctional, and aromatic building blocks, and each was measured for thickness, conductivity, heat stability, wetting, oil mixing, and copper corrosion.
Structure ruled behavior. Compact simple anions gave thin, highly conductive liquids, a sign of loose internal bonding and mobile ions. Branched and aromatic versions ran thicker and conducted less, held together by hydrogen bonds and bulk. One variant with two acid groups stood out as far thicker than its size suggested. The authors map these links to guide lubricant design.
