Abstract:
A Transparent conductor including a conductive layer coated on a substrate is described. More specifically, the conductive layer comprises a network of nanowires which may be embedded in a matrix. The conductive layer is optically transparent and flexible. It can be coated or laminated onto a variety of substrates, including flexible and rigid substrates.
Abstract:
A circuit-connecting material which is interposed between circuit electrodes facing each other and electrically connects the electrodes in the pressing direction by pressing the facing electrodes against each other; the circuit-connecting material comprising as essential components (1) a curing agent capable of generating free radicals upon heating, (2) a hydroxyl-group-containing resin having a molecular weight of 10,000 or more and (3) a radical-polymerizable substance. Also provided are a circuit terminal connected structure and a circuit terminal connecting method which make use of such a material.

Abstract:
A method for the preliminary treatment of a material to be subjected to electroless plating, characterized in that a polymer material is mixed with an inorganic filler, a formed product obtained from the resultant mixture is immersed in an anionic aqueous solution containing a noble metal. A formed product having been immersed as mentioned above is then subjected to electroless plating.
Abstract:
A composite film which comprises a film (A) formed of a ring-structure polymer having repeating units formed by the ring-opening type or addition type polymerization of a ring-structure monomer and a film (B) formed of a polycondensation type polymer and wherein at least two layers are adjacent to each other directly or via an adhesive layer.
Abstract:
This invention relates to printed circuit boards having improved fire resistance and improved environmental stability. The invention provides halogen-free fire retardant printed circuit boards incorporating potentially flammable polymers. Flame resistant thermoplastic layers prevent combustion of thermosetting polymers, as well as adding strength to the laminate, resulting in a less brittle thin core than the prior art. The flame resistant circuit board is cost efficient, environmentally safe and has excellent properties, including a decreased probability of shorting, good dielectric breakdown voltage, a smooth surface and good electrical/thermal performance.
Abstract:
A composite film having a layer structure of at least two layers, wherein a film (A) formed from a ring structure-containing polymer comprising a repeating unit derived from ring-opening or addition polymerization of a monomer having a ring structure, and a film (B) formed from a polycondensation polymer adjoin each other directly or through an adhesive layer.
Abstract:
An inorganic filler is added to a polymeric material. An obtained polymeric mold is irradiated with a laser and immersed in an anionic noble metal aqueous solution and thereafter electroless plating is performed.
