    Abstract: A composition may have metal nanoparticles having a diameter of 20 nanometers or less and have a fusion temperature of less than about 220 0C. A method of fabricating the metal nanoparticles may include preparing a solvent, adding a precursor with a metal to the solvent, adding a first surfactant, mixing in a reducing agent, and adding in a second surfactant to stop nanoparticle formation. Copper and/or aluminum nanoparticle compositions formed may be used for lead-free soldering of electronic components to circuit boards. A composition may include nanoparticles, which may have a copper nanocore, an amorphous aluminum shell and an organic surfactant coating. A composition may have copper or aluminum nanoparticles. About 30-50% of the copper or aluminum nanoparticles may have a diameter of 20 nanometers or less, and the remaining 70-50% of the copper or aluminum nanoparticles may have a diameter greater than 20 nanometers.

    Abstract: Functional composite materials comprise elemental inorganic particles within an organic matrix. The elemental inorganic materials generally comprise elemental metal, elemental metalloid, alloys thereof, or mixtures thereof. In alternative or additional embodiments, the inorganic particles can comprise a metal oxide, a metalloid oxide, a combination thereof or a mixture thereof. The inorganic particles can have an average primary particle size of no more than abut 250 nm and a secondary particle size in a dispersion when blended with the organic matrix of no more than about 2 microns. The particles can be substantially unagglomerated within the composite. The organic binder can be a functional polymer such as a semiconducting polymer. The inorganic particles can be surface modified, such as with a moiety having an aromatic functional group for desirable interactions with a semiconducting polymer. Appropriate solution based methods can be used for forming the composite from dispersions of the particles. The composites can be processed into products, such as printed electronics devices.

    Abstract: Respective conductive layers each forming an electrode and terminals are formed on the opposite surfaces of first and second substrates (10, 20). When the first and second substrates are bonded to each other with an anisotropic conductive adhesive material held therebetween, a first electrode (12) of the first substrate (10) and a first electrode lead terminal (24) of the second substrate (20) are electrically connected together with a preset interval apart. The anisotropic conductive adhesive material includes, mixed into an adhesive material (36), non-conductive particles, conductive particles (32) having a grain size gamma 1 that allows a persistence to be within a proper range with respect to an upper limit value Gmax of variations in an adhesion setting gap Gp, and conductive particles (34) having a grain sized gamma 2 that allows a persistence to be within a proper range with respect to a lower limit Gmin of variations in an adhesion setting gap Gp, thereby positively ensuring an electrical conduction despite variations in a gap between substrates to be pasted together.
