There is provided an electrically peelable adhesive composition that is for forming an adhesive layer which has high adhesion and can be easily peeled off by applying a voltage for a short time even at a low voltage. In addition, there is provided an adhesive sheet including an adhesive layer formed of the composition that has high adhesion and can be easily peeled off by applying a voltage for a short time even at a low voltage, and a joined body of the adhesive sheet and an adherend. The electrically peelable adhesive composition of the invention includes a polymer and an ionic liquid, in which an anion of the ionic liquid is a bis(fluorosulfonyl)imide anion. A content of the ionic liquid is preferably 0.5 to 30 parts by weight with respect to 100 parts by weight of the polymer.

Electrically peelable adhesive composition, adhesive sheet, and joined body

A double-sided adhesive sheet has a laminate structure including a first adhesive layer containing an electrolyte, a second adhesive layer, and a conduction substrate. A double-sided adhesive sheet joined body includes, for example, an adhesive sheet having such a laminate structure, a first conductive adherend to which the first adhesive layer adheres, and a second adherend to which the second adhesive layer adheres. A method for joining/separating adherends includes joining first and second adherends to each other via the adhesive sheet, then applying a voltage to the first adhesive layer so as to generate a potential difference in a thickness direction of the first adhesive layer, and separating the first and second adherends from each other.

Double-sided adhesive sheet, joined body comprising double-sided adhesive sheet, and method for joining/separating adherends

A sticky cleaner is provided for use in removing organic dirt stuck on a surface of an article. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt as it makes contact with the surface of the article. The dirt-collecting member comprises a PSA at a part where it makes contact with the surface of the article. The PSA comprises, as its base polymer, an acrylic block copolymer having a hard segment (A) and a soft segment (B) in one molecule.

Sticky cleaner for removing organic dirt

Provided is a cleaner that can easily and efficiently remove organic dirt accumulated on a flat plate surface such as a display-input member (touch panel member) in a portable device. The cleaner () provided by the present invention is a pressure-sensitive adhesive plate surface cleaner () that comprises a pressure-sensitive adhesive body () having a removable pressure-sensitive adhesive and is used so as to allow the pressure-sensitive adhesive body () to contact a flat plate surface () of a plate such as a portable device () having a flat surface in order to remove organic dirt accumulated on the plate surface ().
