A composition includes one or more monomeric units having a structure of Formula (I). The one or more monomeric units in the composition can encapsulate a hydrophobic material. Further, the invention provides a method of preparing said composition. The present invention also provides a method of killing or controlling the growth of microorganisms by contacting the microorganisms with said composition.

Supramolecular polymer composition and method of preparation thereof

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.

Slippery self-lubricating polymer surfaces

A method of preparing a composite includes providing a porous material including a polymeric network and a polar particle; depositing an ink onto the porous material via a printing process; and delivering a lubricating fluid to the porous material to form a coating. A composite is obtained from the method, and an anti-fouling product including the composite is provided.

Method for preparing composite materials

The present invention has provided a self-healable material configured to self-heal in the presence of moisture or in aqueous condition environment after physical damages. The material includes or made from a compound of formula IV 

Underwater self-healable materials, methods of making thereof, and products comprising same

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.
