A method for fabricating, and curing, nanocomposite adhesives including introducing nanoheater elements into a heat-curing adhesive to fabricate a nanocomposite adhesive, and providing a radio-frequency (RF) electromagnetic wave to the nanocomposite adhesive to heat, and cure the nanocomposite adhesive. The nanocomposite adhesive is physically applied to first and second materials to bond the first and second materials upon curing of the nanocomposite adhesive, and the RF electromagnetic wave has a frequency in the radio-frequency range, having energy that is transferred to the nanoheater elements by electromagnetic wave interactions with permanent and induced dipoles, intrinsic photon-phonon interaction, or interactions with nanoheater defects and grain structures.

[Problems] Objects include providing a pressure sensitive adhesive sheet for batteries that is excellent in the insulation properties even after heated to high temperatures and also excellent in the insulation properties even when immersed in an electrolyte solution for a long time and then heated to high temperatures and also providing a lithium-ion battery in which the pressure sensitive adhesive sheet for batteries is used. [Solution] A pressure sensitive adhesive sheet for batteries (1), comprising: a base material (11); a hard coat layer (12) provided at one side of the base material (11); and a pressure sensitive adhesive layer (13) provided at a side of the hard coat layer (13) opposite to the base material (11), the hard coat layer (12) being formed of a composition for hard coat layer that contains a metal oxide sol, the metal oxide sol being a sol of a metal oxide that has insulation properties.

One-component toughened epoxy structural adhesives contain fibrous mineral fillers that have an aspect ratio of ?6. The presence of the fibrous filler leads to a significant increase in elastic modulus while having little if any adverse effect on other properties such as dynamic impact peel resistance.

A method of preparing a composite preform includes applying a tacky preceramic-polymer-based adhesive on a first fiber array arranging a second fiber array on the first fiber array, the adhesive holding the first and second fiber arrays together. A composite component is also disclosed.

A medium such as an ink or sealant for disclosing movement is provided. Also provided are a tape having the medium applied to it, and a method of disclosing movement of one or more elements. The medium is applicable as a settable liquid or paste to components, such as a nut and bolt or a flexible hydraulic hose, for which untightening or kinking movement is to be detected. The medium has an appearance, e.g. color, and contains distributed microspheres containing a second liquid having a different, usually much brighter, appearance. Once the medium is set, unwanted movement, such as untightening of the nut or kinking of the hose, will fracture the microspheres and the second liquid will be released to transform the appearance of the medium and alert an observer.

Provided is a pressure-sensitive adhesive structure including a carbon nanotube aggregate formed on a base material in which carbon nanotubes forming the carbon nanotube aggregate are hardly detached. The pressure-sensitive adhesive structure of the present invention includes: a base material; an intermediate layer; and a carbon nanotube aggregate layer, wherein the carbon nanotube aggregate layer includes a plurality of carbon nanotube aggregates, wherein the intermediate layer includes a layer containing the carbon nanotubes and a fixing agent, and wherein the intermediate layer has a thickness of 100 nm or more.
