20080315159 | Method for producing conductive thermoplastic elastomer composition and conductive roller composed of same - A conductive thermoplastic elastomer composition including a continuous phase and first and second uncontinuous phases. The continuous phase and the first and second uncontinuous phases form a sea-island structure; and the first and second uncontinuous phases independently forming island structures. In this structure, the continuous phase contains a composition (A) which is a mixture of a thermoplastic elastomer and a thermoplastic resin; the first continuous phase contains a rubber component (B) containing at least one of diene rubber and ethylene-propylene-diene rubber; and the second continuous phase contains an ethylene oxide-propylene oxide-allyl glycidyl ether copolymer containing an anion-containing salt having a fluoro group and a sulfonyl group (component (C)). | 12-25-2008 |
20100301282 | CONDUCTIVE ELASTOMER MATERIAL, AND CONDUCTIVE SHEET AND CONDUCTIVE SEAMLESS BELT EACH MADE OF THE MATERIAL - Disclosed is a conductive elastomer material from which a molded material having good conductivity and excellent bending resistance can be obtained. This conductive elastomer material is capable of reducing variations in in-plane electrical resistively of sheet-like molded articles. Specifically disclosed is a conductive elastomer material which is characterized by being obtained by dispersing carbon nanotubes into a base component which is composed only of a thermoplastic elastomer. The conductive elastomer material is also characterized in that the carbon nanotubes have a diameter of 30-300 nm and an aspect ratio of 10-1000, and 0.01-10 parts by mass of the carbon nanotubes are blended per 100 parts by mass of the base component. | 12-02-2010 |
