Abstract: A polarizing dye dispersion, a light-polarizing article and a process for making light-polarizing article utilizing the polarizing dye dispersion. The aqueous polarizing dye dispersion comprises, in addition to a polarizing dye material, a non-ionic surfactant material comprising a plurality of surfactant molecules represented by the following general formula (I): wherein: the average of the number n of all the surfactant molecules ranges from 9 to 200; m is 1 or 2; R, identical or different for each surfactant molecule and each occurrence, independently is an alkyl; at least one R on each surfactant molecule is a C6-C12 straight-chain or branched alkyl; and X, identical or different for each surfactant molecule, independently is an H or a C1-C4 alkyl.

Abstract: Described herein are polarizing articles and methods of making the same. The methods are useful in preparing polarizing articles having high durability and increased polarizing efficiency. The polarizing articles are useful in any article where it is desirable to reduce or remove glare.

Abstract: A method of preparing a polarizing dye receiving surface includes bringing the polarizing dye receiving surface into contact with a brushing surface of a brush pad carrying an abrasive material and brushing the polarizing dye receiving surface with the brushing surface in one or more brushing strokes. Each brushing stroke comprises effecting a unidirectional relative motion between the polarizing dye receiving surface and the brushing surface along a brushing path. The polarizing dye receiving surface is separated from the brushing surface after the brushing.

Abstract: A method of making a polarizing article having high polarization efficiency, low haze, and no visible micro-cracks. The article is made by applying an aqueous polarizing dye solution to a surface of a substrate. The polarizing dye solution comprises at least one ammonium salt of a polarizing azoic dye, an activator, and at least one of an acid and a non-polarizing azoic dye.

Abstract: A method for preparing a polarizing substrate comprising a dye layer in which the substrate is contacted with a first solution having a organic silane at a temperature greater than room temperature.

Abstract: Microfluidic devices having wall structures comprised of sintered glass frit and further including a glass, glass-ceramic or ceramic membrane structure sealed by a sintered seal to said wall structures, such that a fluid passage or chamber is defined at least in part by the wall structures and said membrane structure. This allows for changes in pressure within the fluid passage or chamber to cause deflections of the membrane structure, providing for direct measurement of pressure within the device. The microfluidic device may have both floors and walls of sintered frit, or may have only walls of sintered frit, with planar floor-like substrate structures, thicker than the membrane structure defining the vertical boundaries of the internal passages. The device may include multiple fluid passages or chambers each defined at least in part by a membrane structure. Multiple membrane structures may be used in a single device, and one single membrane structure may be used for multiple passages or chamber.
