An electro-optic display comprises a layer (130) of a solid electro-optic material, at least one electrode disposed adjacent the layer (130) of electro-optic material, and a layer (180) of a lamination adhesive interposed between the layer (130) of electro-optic material and the electrode, the lamination adhesive (180) having a higher electrical conductivity in a direction perpendicular to the layer of lamination adhesive than in the plane of the layer.

An electro-optic display comprises first and second substrates, and an adhesive layer and a layer of electro-optic material disposed between the first and second substrates. The adhesive layer has a volume resistivity in the range of about 10<9 >to about 10<11 >ohm cm and comprises a mixture of an adhesive material having a volume resistivity of at least about 5x10<11 >ohm cm and a filler having a volume resistivity not less than about 10<7 >ohm cm, the filler being present in the mixture in a proportion above its percolation threshold in the adhesive material.

Carbon fibrous conjunct is provided by adding to carbon fibrous structures, which each comprises a three dimensional network of carbon fibers each having an outside diameter of 15-100 nm, wherein the carbon fibrous structure further comprises a granular part with which the carbon fibers are bound in the state that the carbon fibers extend outwardly from the granular part, a binder for binding the carbon fibrous structures. The fine carbon fibrous structures having such unique configuration and also bearing physical properties suitable for a filler for a composite material can be provided with a good handleability by this carbon fibrous conjunct. Composite material is prepared by adding to the matrix the carbon fibrous conjuncts, at an amount of 0.1 to 30% by weight based on the total weight of the composite material.

Described are fluorochemical surfactants derived from nonafluorobutanesulfonyl fluoride that contain polyalkyleneoxy side chains and may be copolymerized with acrylic acid or methacrylic acid to form polyacrylates or polymethacrylates. The surfactants surprisingly lower the surface tension of water and other liquids in the same or similar low values achieved by premier surfactants such as those derived from perfluorooctane sulfonyl fluoride.

The invention relates to a high-temperature resisting adhesive and a preparation method thereof; the adhesive is formed by the following ingredients: carboxyl contained polyimide resin powder, epoxide resin, curing agent and organic solvent with weight ratio of 1:10-20:0.1-2:20-30. The preparation method of the high-temperature resisting adhesive comprises the following steps: adding the carboxylcontained polyimide resin powder, the epoxide resin and the curing agent into a reaction kettle, heating the reaction kettle to 80-90 DEG C for carrying out stirring reaction for 0.5-1.5 hours, and then adding the organic solvent continuously, and stirring the mixture uniformly at room temperature, thus obtaining the high-temperature resisting adhesive. The preparation method has simple process and low cost and is environment-friendly, the preparation process can be carried out in a general device, thereby being suitable for industrial production.

The present invention realizes a display device or input device having excellent ultraviolet protection property for the touch panel, display element or the like, while retaining optical characteristics, even when a small amount of or no optical film is used. The pressure-sensitive adhesive sheet of the present invention has a total light transmittance of 85% or more, a light transmittance at a wavelength of 380 nm of 5% or less, and a haze of 3% or less. The pressure-sensitive adhesive sheet preferably includes a pressure-sensitive adhesive layer containing an acrylic polymer and a triazine-based ultraviolet absorber.

Incorporating organophilic clay into hot melt adhesive compositions, particularly those comprising semi-crystalline, thermoplastic polymers, greatly improves the adhesive properties in many respects. Some of these improvements are particularly beneficial to the specific use of hot melt adhesives filled with electrically conductive particles for use as electrically conductive adhesives.

The invention discloses water-based polyurethane composite adhesive for tanning and a preparation method and application of the composite adhesive, belongs to the technical field of water-based polyurethane composite adhesive preparation methods, and in particular relates to a method for preparing composite adhesive in the fields of artificial leather and synthetic leather. The method for preparing the water-based polyurethane composite adhesive for tanning is characterized by comprising the following steps of: reacting polyol polymer and isocyanate, adding chain extender, hydrophilic chain extender, cross linker, catalyst and solvent, reacting, cooling and emulsifying, to obtain emulsion; and mixing the emulsion, curing agent, wetting agent, tackifier, adsorbent and thickening agent uniformly, and thus obtaining the hot-melt adhesive for artificial leather adhesive layers. The water-based polyurethane composite adhesive for tanning is used for compounding polyvinyl chloride (PVC) / cloth for artificial leather of luggage and clothes. The prepared water-based polyurethane composite adhesive for tanning has high adhesive fastness and good water and solvent resistance, and can be applied to processes of knife coating, roll coating and the like of binding materials of middle layers of artificial leather and synthetic leather in the fields of textiles, leather processing and the like.
