Abstract

Superoleophilic particles and surfaces and methods of making the same are described. The superoleophilic particles can include porous particles having a hydrophobic coating layer deposited thereon. The coated porous particles are characterized by particle sizes ranging from at least 100 nm to about 10 .mu.m and a plurality of nanopores. Some of the nanopores provide flow through porosity. The superoleophilic particles also include oil pinned within the nanopores of the porous particles The plurality of porous particles can include (i) particles including a plurality of spaced apart nanostructured features comprising a contiguous, protrusive material, (ii) diatomaceous earth particles, or (iii) both. The surfaces can include the superoleophilic particles coupled to the surface.

Silicon release coating, method of making same, and method of using same

Patent Jonczyk, Ralf [Wilmington, DE]

A method of making a release coating includes the following steps: forming a mixture that includes (a) solid components comprising (i) 20-99% silicon by weight and (ii) 1-80% silicon nitride by weight and (b) a solvent; applying the mixture to an inner portion of a crucible or graphite board adapted to form an ingot or wafer comprising silicon; and annealing the mixture in a nitrogen atmosphere at a temperature ranging from 1000 to 2000.degree. C. The invention may also relate to release coatings and methods of making a silicon ingot or wafer including the use of a release coating.

Abrasion resistant coating and method of making the same

Patent Sordelet, Daniel J [Ames, IA]; Besser, Matthew F [Urbandale, IA]

An abrasion resistant coating is created by adding a ductile phase to a brittle matrix phase during spray coating where an Al--Cu--Fe quasicrystalline phase (brittle matrix) and an FeAl intermetallic (ductile phase) are combined. This composite coating produces a coating mostly of quasicrystal phase and an inter-splat layer of the FeAl phase to help reduce porosity and cracking within the coating. Coatings are prepared by plasma spraying unblended and blended quasicrystal and intermetallic powders. The blended powders contain 1, 5, 10 and 20 volume percent of the intermetallic powders. The unblended powders are either 100 volume percent quasicrystalline or 100more »« less

Subwavelength coatings and methods for making and using same

Patent Alvine, Kyle J.; Bernacki, Bruce E.

Methods are disclosed for forming subwavelength coatings for use in the UV, visible, or infrared part of the electromagnetic spectrum. A first material and a second material are deposited onto a substrate. The first material may include dielectric spheres of subwavelength size that self-assemble on the substrate to form a template or scaffold with subwavelength size voids between the spheres into which the second material is deposited or filled. First and second materials are heated on the substrate at a preselected temperature to form the subwavelength coating.

Electrothermal coating with nanostructures mixture and method for making the same

Patent Lui, Feng; Hui, Chao

An electrothermal coating can include a nanostructure mixture randomly dispersed in a polymer matrix with more than one type of low-dimensional nanostructure. These types of low-dimensional nanostructures can include a combination of a nanospheroid plus one or both of a linear nanostructure and a planar nanostructure. Useful conductivity is achieved, while concentration of the mixed nanostructures is within the cured polymer composite coating being below the percolation limit of each individual carbon nanostructure type, alone, within an identical polymer matrix.
