Self-lubricating and wear-resistant epoxy resin coatings based on the “soft-hard” synergistic mechanism for rapid self-healing under photo-thermal conditions

•Realization of the perfect combination of hard “micro-bearings” and soft lubrication phases.•A photothermal self-healing wear-resistant coatings with excellent self-lubricating properties.•Effective self-healing properties in a variety of harsh environments.•Continuously effective self-lubricating properties in dry and wet environments.
