摘要:
A method of synthesizing multilayer heterostructures including an inorganic oxide layer residing on a solid substrate is described. Exemplary embodiments include producing an inorganic oxide layer on a solid substrate by a liquid coating process under relatively mild conditions. The relatively mild conditions include temperatures below 225° C. and pressures above 9.4 mb. In an exemplary embodiment, a solution of diethyl aluminum ethoxide in anhydrous diglyme is applied to a flexible solid substrate by slot-die coating at ambient atmospheric pressure, and the diglyme removed by evaporation. An AlOx layer is formed by subjecting material remaining on the solid substrate to a relatively mild oven temperature of approximately 150° C. The resulting AlOx layer exhibits relatively high light transmittance and relatively low vapor transmission rates for water. An exemplary embodiment of a flexible solid substrate is polyethylene napthalate (PEN). The PEN is not substantially adversely affected by exposure to 150° C.

An apparatus and method is provided for preventing smudges (608) including oils and dust from collecting on a portable electronic device display (110, 150, 200, 300). A plurality of islands (606) are formed on a surface of the display device, each island (606) comprising a transparent material and having a diameter of between 5 and 200 nanometers. Liquid (608) forming on the plurality of islands has a large contact angle (610), increasing the likelihood of the liquid migrating from the display device and thereby removing contaminants therewith.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

Aspects of the application provide methods of producing substrates having modified surfaces. In some aspects, methods of surface modification involve treating a surface of a substrate with an organic reagent in vapor phase to form an organic layer over the surface. In some aspects, methods of forming a stable surface coating on an oxidized surface are provided.
摘要:
The ionic liquid-based coating is a coating for both porous and nonporous materials. As non-limiting examples, a porous substrate coated with the ionic liquid-based coating may be used to disinfect and remove microorganisms from air and water, to provide an antimicrobial surface for preventing microbial contamination, or to enhance filtration efficiency of the porous material for airborne and waterborne particulate matter without increasing flow resistance. As a further non-limiting example, a nonporous substrate coated with the ionic liquid-based coating may be used to form a surface capable of self-disinfection from microorganisms contacting surface. The ionic liquid-based coating includes at least one ionic liquid, an adhesive, and at least one additive, which may be a disinfectant, a viscosity modifier, a pH buffer, a fragrance, or combinations thereof.
