Abstract: A method of consolidating thermoplastic fibrous layers. The method begins with providing a plurality of fibers, where the fibers have a core with an exterior surface portion comprising polypropylene and a first layer disposed on at least a portion of the core. The first layer contains a first polymer, where the first polymer contains at least 70% α-olefin units and is characterized by a melting temperature less than the melting temperature of the exterior surface of the core. These fibers are formed into a fibrous layer. Next, a second layer is applied to the fibrous layer such that the second layer covers at least a portion of the first layers of the fibers. The second layer contains a second polymer being a co-polymer having at least 50% α-olefin units which is characterized by a number-average molecular weight of about 7,000 g/mol to 50,000 g/mol, a viscosity of between about 2,500 and 150,000 cP measured at 170° C., and a melting temperature lower than the melting temperature of the exterior surface of the core. The viscosity of the second polymer is less than a tenth of the viscosity of the first polymer measured at 170° C. Next, heat and optionally pressure are applied to the fibrous layer causing at least a portion of the second layers of the fibers in each fibrous layer to fuse to other first or second layers of the fibers within the same fibrous layer, at least a portion of the second layers of the fibers of each fibrous layer fuse with at least a portion of the first or second layers of the fibers in an adjacent fibrous layer, and at least a portion of the interstices to be filled with a blend of the first and second polymers, where the blend filling the interstices comprises at least 80% wt the second polymer.

Abstract: The present invention relates generally to substrates that exhibit useful, auto adaptable surface energy properties that depend on the environment of the substrate. Such surface energy properties provide relatively high advancing and receding contact angles for liquids when in contact with the target substrate surface. The substrates exhibit low surface energy quantities of at most about 20 millijoules per square meter (mJ/m2) at a temperature of about 25 degrees C. and a surface energy greater than about 20 mJ/m2 at, or with exposure to, a temperature of about 40 degrees C. More specifically, encompassed within the present invention are textile substrates having this highly desirable unique surface energy modification property and which exhibit wash durable oil and water repellency and stain release features. Novel compositions and formulations that impart such surface energy modifications to substrates are also encompassed within this invention, as well as methods for producing such treated substrates.

Abstract: The present invention includes methods for fabricating polymer light emitting devices by screen-printing. These light emitting devices use silver paste as the top electrode, eliminating the use of evaporated low work function metal. This is made possible by the presence of a buffer layer such as the sulfonated polyaniline layer in the structure of SCALE devices. These devices allow a very inexpensive and fast means to form stable top electrodes for large-scale polymer light emitting device fabrication.

Abstract: Compositions and methods for treating textile substrates to obtain superior liquid repellent properties are disclosed. Durable microscopic surface structures imparted to the fibrous substrate allow liquids to bead up and roll off of its surface. Mechanical abrasion or sanding techniques may be used to create the microscopic surface structures on the surface of a fibrous textile substrate, without substantially breaking fibers, followed by a chemical treatment using, for example, fluorocarbon-containing repellent compositions. Particles may be employed in combination with repellent compositions to achieve superior repellent properties. A property of the roughened surface fibers, the Roughness Factor, is used to characterize the microscopic surface structures on the treated textile surface. Treated textile substrates are disclosed which achieve superior water and oil repellency, even after multiple abrasion or laundering cycles.
