AbstractTwo-dimensional (2D) organic materials attract much research interest because of their unique properties and potential applications in catalysis, lubrication, and biological medicine. Erucamide is an unsaturated aliphatic primary amide that is widely used to reduce friction in the production of various polymers. In this work, we synthesize single-crystalline 2D erucamide with a facile and scalable method. The thinnest 2D erucamide is similar to 4 nm thick, containing two layers of erucamide molecules; and its lateral size is a few micrometers. We observe a crystalline-to-amorphous transformation for 2D erucamide under electron beam irradiation. More importantly, we systematically investigate the influences of crystallinity on the tribology and thermal properties of 2D erucamide. The crystalline 2D erucamide demonstrates an ultralow friction and enhanced thermal conductivity, which makes it a promising material used in nanoscale lubrication and thermal management.
