An article having a porous surface (SLIPS) infused with a self-healing slippery liquid and method of making. A rough (eg, porous) surface for locking a lubricating fluid called liquid B130 in place to repel a wide range of materials, called object A (solid A or liquid A) 140. 110 is used. Effect SLIPS 110 repels various simple and complex liquids (water, hydrocarbons, crude oil, and blood) 140, maintains low contact angle hysteresis (<2.5 °), and provides liquid repellency after physical damage It is superior to other conventional surfaces in its ability to recover quickly (within 0.1-1 s), resist ice, microbial and insect attachment and function at high pressures (up to at least 690 atm). Some exemplary applications are self-cleaning antifouling materials that operate in energy efficient handling and transportation, light sensing, medicine, and extreme environments.
