Thick, inorganic coatings can be deposited on a polarizer by chemical vapor deposition. In one embodiment, the method can comprise activating a surface of the polarizer with an oxygen plasma in an oven; injecting a solution including tetrakis(dimethylamino)silane dissolved in cyclohexane and water into the oven; and vapor depositing silicon dioxide onto the polarizer. These three steps can be repeated multiple times until desired thickness is attained.

Chemical vapor deposition of thick inorganic coating on a polarizer

An extractive system, such as SPME, has an adsorptive phase in the form of a porous coating that has essentially vertical, mutually supporting, columnar structures with nanospaces at the boundaries of the grains.

Solid phase coatings for microextraction

A wire grid polarizer and method of making a wire grid polarizer can protect delicate wires of the wire grid polarizer from damage. The wire grid polarizer can include a protective-layer located on an array of wires. The array of wires can further be protected by a chemical coating on an inside surface of the air-filled channels, closed ends of the air-filled channels, damaged wires of the array of wires in a line parallel to an edge of the wire grid polarizer, or combinations thereof. The method can include (i) providing the wire grid polarizer, (ii) applying the protective-layer, by physical vapor deposition or chemical vapor deposition but excluding atomic layer deposition, onto the array of wires, (iii) cutting the wire grid polarizer wafer into multiple wire grid polarizer parts, then (iv) protecting the array of wires.

In one or more embodiments, a porous composite particulate material includes a plurality of composite particles including an acid-base-resistant core particle at least partially surrounded by one or more layers of acid-base-resistant shell particles. The shell particles are adhered to the core particle by a polymeric material. The shell particles and/or core particles may be made from an acid-base-resistant material that is stable in harsh chemical conditions. During application of the polymeric material/shell particle bilayer, the core particles are sonicated to homogenize the particle size distribution and minimize agglomeration of particles. Multiple bilayers of polymer/shell particles may be applied. In one embodiment, the core particle comprises generally spherical glassy carbon, while the shell particles may comprise nano-sized diamond particles. Other acid-base-resistant materials may be employed. The porous composite particulate materials may be used in separation technologies, including, but not limited to, chromatography and solid phase extraction.
