Abstract
Official abstract text for this publication.
Provided is a composition that enables excellent dispersibility of an inorganic filler and has excellent oxidation resistance. The composition contains an inorganic filler, a copolymer of a fluoromonomer and an amide bond-containing polymerizable vinyl compound, and a solvent.
First claim
Opening claim text (preview).
1 . A composition comprising: an inorganic filler; a copolymer of a fluoromonomer and an amide bond-containing polymerizable vinyl compound; and a solvent, wherein the amide bond-containing polymerizable vinyl compound is at least one selected from the group consisting of N-vinyl lactam compounds, acyclic N-vinylamide compounds, acyclic N-allyl amide compounds, and N-allyl lactam compounds, and wherein the composition has a mass ratio (inorganic filler/copolymer) of the inorganic filler to the copolymer of 0.4 to 100. 2 . The composition according to claim 1 , wherein the copolymer is a copolymer of at least one fluoromonomer selected from the group consisting of tetrafluoroethylene and hexafluoropropylene and the amide bond-containing polymerizable vinyl compound, and the copolymer contains a unit of the fluoromonomer and a unit of the amide bond-containing polymerizable vinyl compound in amounts of 65 to 7 mol % and 35 to 93 mol %, respectively, of all monomer units. 3 . The composition according to claim 1 , wherein the inorganic filler includes a carbon filler. 4 . The composition according to claim 1 , wherein the inorganic filler includes fibrous carbon. 5 . The composition according to claim 1 , wherein the inorganic filler includes a carbon nanotube. 6 . A laminate comprising: a substrate; and a film that is on the substrate and is obtained from the composition according to claim 1 . 7 . A conductive member comprising the laminate according to claim 6 . 8 . A dispersant for dispersing an inorganic filler in a solvent, the dispersant comprising a copolymer of a fluoromonomer and an amide bond-containing polymerizable vinyl compound.
