20110299025 | OPTICAL CONTROL DEVICES AND METHODS OF MAKING - Herein are disclosed methods by which a layer of oriented chromonic material may be transferred from a flexible substrate to a receiving substrate, so as to form a subassembly for use in the assembly of liquid crystal cells. The oriented chromonic material layer may function as an alignment layer for aligning liquid crystal material, and may also incorporate a pleochroic dye so to function as a polarizing layer. An oriented chromonic material layer of relatively large area can be transferred, which enables the production of relatively large liquid crystal cells for use in, e.g., autodarkening filters such as used for eye protection in welding operations. Curved liquid crystal cells are also disclosed. | 12-08-2011 |
20120276369 | PROTECTIVE COATINGS AND METHODS OF MAKING AND USING THE SAME - Protective coatings are formed on a reflective surface of a substrate by depositing an aqueous coating composition including dispersed silica-containing nanoparticles; and removing at least a portion of the aqueous phase. In some embodiments, the aqueous coating composition includes an acid having a pKa of <3.5 in an amount effective to produce a pH of less than 5. In other embodiments, the aqueous coating composition includes at least one dispersed (co)polymer, which in some embodiments, forms core-shell particle having a dispersed (co)polymer core surrounded by a shell consisting essentially of silica nanoparticles. In some of these embodiments, the pH is at least 5. Also described are methods of making and using the coating compositions to impart soil and stain accumulation resistance and easy cleaning characteristics to light reflective substrates such as construction articles (e.g., roofing materials), light reflective surfaces (e.g. reflective films) and light transmissive surfaces (e.g., photovoltaic cells). | 11-01-2012 |
