Abstract:
The present invention provides antimicrobial coatings for coating substrate surfaces, particularly medical devices, for preventing bacterial adhesion and biofilm formation by inhibiting microbial growth and proliferation on the coating surface. The antimicrobial coatings are composed of a hydrogel and a bioactive agent including a substantially water-insoluble antimicrobial metallic material that is solubilized within the coating. Antimicrobial coating formulations for obtaining such coatings, and coating methods are also described.

The present disclosure provides a solvent for reducing resist consumption, which includes a first solvent selected from the group consisting of alkylene glycol alkyl ether acetate, alkylene glycol alkyl ether and a combination thereof, and a second solvent having a hydrogen bonding Hansen parameter lower than 5.34 and an evaporation rate (n-BuAc=1) lower than 0.6. A volume ratio of the first solvent to the second solvent is in a range of 0/100 to 90/10. A resist dispense volume for a 300 mm wafer is less than 0.6 cc, or a resist dispense volume for a 450 mm wafer is less than 1.1 cc.
Abstract:
Methods and compositions disclosed herein relate to liquid repellant surfaces having selective wetting and transport properties. An article having a repellant surface includes a substrate comprising fabric material and a lubricant wetting and adhering to the fabric material to form a stabilized liquid overlayer, wherein the stabilized liquid overlayer covers the fabric material at a thickness sufficient to form a liquid upper surface above the fabric material, wherein the fabric material is chemically functionalized to enhance chemical affinity with the lubricant such that the lubricant is substantially immobilized on the fabric material to form a repellant surface.
Abstract:
Encapsulated switches are disclosed which substitute non-toxic gallium alloy for mercury. In one embodiment, wetting of the interior surfaces of the housing is prevented by coating the surfaces with an electrically insulative inorganic non-metallic material, such as alumina or boron nitrate. According to another embodiment, a perfluorocarbon liquid is employed as the anti-wetting agent.
Abstract:
A method for manufacturing a separator includes (S1) preparing a porous substrate having pores, (S2) coating at least one surface of the porous substrate with a first solvent, (S3) coating the first solvent with a slurry containing inorganic particles dispersed therein and formed by dissolving a binder polymer in a second solvent, (S4) drying the first and second solvents simultaneously to form a porous organic-inorganic composite layer on the porous substrate. Since the phenomenon that the pores of the porous substrate are closing by the binder polymer is minimized, it is possible to prevent the resistance of the separator from increasing due to the formation of the porous organic-inorganic composite layer.
