Patent ID: 8658725

Claim:
A material comprising a first polyrotaxane and a second polyrotaxane, wherein the first polyrotaxane comprises a first pseudopolyrotaxane, which has a first linear molecule and a first cyclic molecule(s) in which the first linear molecule is included in a cavity (cavities) of the first cyclic molecule(s) in a skewered manner, and first capping groups, each of which locates at each end of the first pseudopolyrotaxane in order to prevent the dissociation of the first cyclic molecule(s), the second polyrotaxane comprises a second pseudopolyrotaxane, which has a second linear molecule and a second cyclic molecule(s) in which the second linear molecule is included in a cavity (cavities) of the second cyclic molecule(s) in a skewered manner, and second capping groups, each of which locates at each end of the second pseudopolyrotaxane in order to prevent the dissociation of the second cyclic molecule(s), the first and second polyrotaxanes are crosslinked with each other via the first and second cyclic molecules, the material is free from solvent, the material has a dielectric constant at 1 kHz of 6.0 or more, and the material comprises at least one powder, which imparts said dielectric constant to the material, selected from the group consisting of metal oxides, metal hydroxides, metals and carbon, and the metal oxide is selected from the group consisting of MgSiO 4 , MgTiO 3 , ZnTiO 3 , Zn 2 TiO 4 , CaTiO 3 , SrTiO 3 , SrZrO 3 , BaTiO 3 , BaTi 2 O 5 , BaTi 4 O 9 , Ba 2 Ti 9 O 20 , Ba 2 (Ti, Sn) 9 O 20 , ZrTiO 4 , (Zr, Sr)TiO 4 , BaNd 2 Ti 5 O 14 , BaSm 2 TiO 14 , Bi 2 O 3 BaONd 2 O 3 TiO 2 , PbOBaONd 2 O 3 TiO 2 , (Bi 2 O 3 , PbO)BaONd 2 0 3 TiO 2 , La 2 Ti 2 O 7 , Nd 2 Ti 2 O 7 , (Li, Sm)TiO 3 , Ba(Mg 1/3 Ta 2/3 )O 3 , Ba(Zn 1/3 Ta 2/3 )O 3 , Ba(Zn 1/3 Nd 2/3 )O 3 , and Sr(Zn 1/3 Nd 2/3 )O 3 .
