Dry film lubricants containing graphene improve the wear resistance and the frictional behavior of the lubricant.

The present invention provides liquid crystal (LC)-infused materials and methods for detecting compounds or impurities in liquid samples using such materials. These slippery materials comprise a lubricating liquid, preferably a thermotropic liquid crystal, and a solid substrate able to immobilize or host the lubricating liquid. The portion of the substrate coated by the lubricating fluid forms a slippery surface able to allow droplets of various materials to slide off the slippery surface in a manner dependent on the chemical composition of the droplet, which can be used to detect the presence of analytes, impurities and other molecules within the droplet.

Novel, lubricious antimicrobial coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes at low temperatures that do not deform the device and preserves the antimicrobial effectiveness of the antimicrobial agent. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.
