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： Microstructured hybrid actuator assemblies in which microactuators carrying designed surface properties to be revealed upon actuation are embedded in a layer of responsive materials. The microactuators in a microactuator array reversibly change their configuration in response to a change in the environment without requiring an external power source to switch their optical properties.

摘要： The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS) that can be modified as desired. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of objects, referred to herein as Object A (Solid A or Liquid A). Use of an external stimuli or degradation of the Liquid B can be utilized to change the characteristics of SLIPS structures reversibly or irreversibly that may be desired in a number of different applications. Numerous characteristics, such as adhesion, optical, mechanical, and the like, can be dynamically changed.

摘要： Aspects of the present application provides for enhanced catalytic materials, which can feature multiple functional and/or catalytic species, and methods of their formation. The materials can include catalytic nanoparticles (NPs) partially embedded within a supporting matrix. Treatment of the material, e.g., thermal, optical, microwave, plasma, and/or chemical treatment, can lead to the formation of functionally, e.g., catalytic or co-catalytic, relevant chemical and structural/morphological species or features at the NP-matrix, NP-pore, and matrix-pore interfaces. The treated material is characterized by enhanced properties, e.g., greater mechanical stability.
