Adhesive compositions, articles, and methods are described. The electronic may comprise: i) a conductive metallic substrate; ii) an insulating resin layer; and iii) and an adhesive layer disposed between the substrate and insulating resin layer. The adhesive layer comprises at least 50 wt. % of polyimide resin comprising maleimide moieties; and at least 0.25 wt. % of an amine compound. In some embodiments, the conductive metallic substrate comprises copper, such as copper traces.

Disclosed is a fire protection layer composite for use as preventive fire protection material, and to a method for producing a fire protection layer composite. The invention relates to non-flammable and fire-retardant materials, in particular film composites which are intumescent in the event of a fire. The fire protection layer composite comprises at least one plastics layer, which surrounds a transparent fire protection layer, wherein the fire protection layer comprises an intumescent material. The fire protection layer composite makes it possible to achieve effective fire protection in a compact design. The fire protection layer composite does not produce soot or release toxic flue gases, even under the influence of very high temperatures. This prevents danger to the health of a user of the fire protection layer composite in the event of a fire.

Disclosed is a single wall carbon nanotube (SWCNT) film electrode (FE), all-organic electroactive device systems fabricated with the SWNT-FE, and methods for making same. The SWCNT can be replaced by other types of nanotubes. The SWCNT film can be obtained by filtering SWCNT solution onto the surface of an anodized alumina membrane. A freestanding flexible SWCNT film can be collected by breaking up this brittle membrane. The conductivity of this SWCNT film can advantageously be higher than 280 S/cm. An electroactive polymer (EAP) actuator layered with the SWNT-FE shows a higher electric field-induced strain than an EAP layered with metal electrodes because the flexible SWNT-FE relieves the restraint of the displacement of the polymeric active layer as compared to the metal electrode. In addition, if thin enough, the SWNT-FE is transparent in the visible light range, thus making it suitable for use in actuators used in optical devices.
