摘要： The present disclosure describes a strategy to create self-healing, slippery self-lubricating polymers. Lubricating liquids with affinities to polymers can be utilized to get absorbed within the polymer and form a lubricant layer (of the lubricating liquid) on the polymer. The lubricant layer can repel a wide range of materials, including simple and complex fluids (water, hydrocarbons, crude oil and bodily fluids), restore liquid-repellency after physical damage, and resist ice, microorganisms and insects adhesion. Some exemplary applications where self-lubricating polymers will be useful include energy-efficient, friction-reduction fluid handling and transportation, medical devices, anti-icing, optical sensing, and as self-cleaning, and anti-fouling materials operating in extreme environments.

摘要： The permeability of cementitious materials is reduced by chemically functionalizing the surface and infiltrating it with a lubricant. However, the development process was not trivial, where additional steps were required to optimize the cement types used (e.g. geopolymer and Portland cement). It was observed that after the complete modification, the wetting behavior of the cement against water changed from dynamic wetting to hydrophobic (water droplets with water CA>120°. Furthermore, compression testing showed that there was negligible difference in the bulk mechanical properties, more specifically the ultimate strength and the Young's modulus. The result is cementitious materials with omniphobicity and damage-tolerant resistance to permeable fluids.
