Friction heat-driven robust self-lubricity of n-alkanols/epoxy resin coatings enabled by solid-liquid phase transition

Due to the inherent damage effect, friction heat is commonly undesirable yet inevitable in moving components. Hence, obtaining robust running of mechanical assemblies under high sliding velocity is challenging. Herein, we report an alternative strategy to design robust self-healing lubricity materials by taking advantage of friction heat-driven solid-liquid phase transition employing facile coatings of
