Abstract

The purpose of the present invention is to provide an adhesive tape which is capable of exhibiting excellent adhesive force to a silicone-based adherend. An adhesive tape according to the present invention has an adhesive layer that contains a (meth)acrylic copolymer. A laminate which is obtained by bonding the adhesive tape to a silicone rubber that is affixed to an SUS304 plate is left to stand for 72 hours in an environment at 25°C and 50% RH, and is subsequently subjected to a peel test in which the adhesive tape in the laminate is peeled at 180° from the silicone rubber under conditions of 23°C, 50% RH, and a peeling rate of 300 mm/min using a tensile tester. If the surface, from which the adhesive tape has been separated, of the silicone rubber after the peel test is cleaned at least eight times with ethyl acetate and is subsequently subjected to TOF-SIMS measurement, the peak intensity (26/total) of negative ions in a region where m/z is 26 with respect to the peak intensity (total) of all negative ions is 2.50 × 10-3 or more.

One aspect of the present invention provides a production device for a carbon material. The production device comprises a first reaction unit that produces carbon monoxide from carbon dioxide, a second reaction unit that produces a carbon material from carbon monoxide, and a gas line that connects the first reaction unit and the second reaction unit. The first reaction unit has at least one reactor that contains a reducing agent. By contact with a starting material gas that includes carbon dioxide, the reducing agent reduces the carbon dioxide to carbon monoxide and is oxidized, and by contact with a reducing gas that includes a reducing substance, the oxidized reducing agent is reduced.

Abstract

Provided are conductive particles capable of achieving both low connection resistance and high conduction reliability even when electrodes are electrically connected at relatively low pressure. Conductive particles according to the present invention comprise a base material particle and a conductive layer disposed on the surface of the base material particle. In a correlation diagram of a compression test in which the conductive particles are compressed, with compression displacement on the X-axis and compression load on the Y-axis, a variation indicating brittle fracture of the conductive layer is observed in the correlation line before a variation indicating destruction of the base material particle is observed.
