Hybrid transparent conducting materials are disclosed which combine a polycrystalline film and conductive nanostructures, in which the polycrystalline film is “percolation doped” with the conductive nanostructures. The polycrystalline film preferably is a single atomic layer thickness of polycrystalline graphene, and the conductive nanostructures preferably are silver nanowires.

Water-based adhesive compositions are improved by the incorporation of hollow polymeric microspheres having outer surfaces coated with one or more barrier materials such as calcium carbonate particles. The adhesive compositions exhibit enhanced rheology, sprayability, drying time, tack and storage stability as compared to analogous adhesives that are not modified with coated hollow polymeric microspheres. Such compositions are useful as both contact adhesives as well as wet bonding one-way adhesives.

The invention provides an anisotropic conductive adhesive film and an electronic device. The anisotropic conductive adhesive film comprises a base film and microcapsule structures, wherein the microcapsule structures are set on the base film, and each of the microcapsule structures comprises a metallic conductive particle, a normal-temperature curable macromolecular polymer coated on the outside of the metallic conductive particle and a microcapsule wall coated on the outside of the macromolecular polymer, and an adhesive glue is adhered to the external surface of the microcapsule wall. When in use, the microcapsule structure is destroyed by pressurizing, the conductive particle and the normal-temperature curable macromolecular polymer contained inside the microcapsule wall leak out, and the normal-temperature curable macromolecular polymer leaked out is cured, so that electrical conduction and connection of a microelectronic apparatus can be achieved at normal temperature via the anisotropic conductive adhesive film.

Solar-reflective roofing granules having deep-tone colors are formed by coating base mineral particles with a coating composition including an infrared-reflective pigment. Color is provided by a colored infrared pigment, a light-interference platelet pigment, or a metal oxide.

The present invention provides an advantageous method for producing a coating (3) increasing the coefficient of friction on a surface (5) of an element (6), wherein the method comprises the following steps: a) activating of hard particles (1) partially or completely covered by a bonding agent (2) in a non-thermal plasma (low-temperature plasma) at atmospheric pressure; and b) producing a layer (3) increasing the coefficient of friction on a surface (5) of the element (6) by depositing the hard particles (1), which are activated by the non-thermal atmospheric pressure plasma and which are coated with the bonding agent onto the surface (5) of the element (6). Specifically, for elements having a complicated shape or having a big size, this method is more efficient than known methods. No matrix or intermediate layers are necessary to fix the hard particles. The anchoring of the hard particles takes place directly in the joining surfaces themselves.

In an injection molded product of the invention, an unevenness forming portion having unevenness formed by thermal expansion of thermally expandable capsules is formed. The injection molded product includes a highly expanded portion that is formed at a surface side of the unevenness forming portion in a thickness direction of the injection molded product and in which the thermally expandable capsules are thermally expanded, and a main body portion that is a portion adjacent to the highly expanded portion in the thickness direction and in which the thermally expandable capsules are substantially not thermally expanded. The thickness of the highly expanded portion is a half or smaller than the thickness of the injection molded product in the unevenness forming portion, and a polymer material of the highly expanded portion and a polymer material of the main body portion are the same polymer material.

A shingle includes a substrate having an asphalt coating on a top surface of the substrate and on a bottom surface of the substrate. A surface layer of granules is embedded in the asphalt on the top surface of the substrate. A backdust layer of particles is embedded in the asphalt on the bottom surface of the substrate. A sealant is disposed on the backdust. A hydrophobic material is applied to the sealant.
