  • Material having cross-linked polyrotaxane, and method for producing same
    Patent number: 8658725
    Abstract: Disclosed are a material having high flexibility and a high dielectric constant, and a method for producing same: a material having a first polyrotaxane and a second polyrotaxane, wherein the first polyrotaxane comprises first blocking groups being disposed at both ends of a first pseudo-polyrotaxane—formed from the opening of a first circular molecule being enclathrated by being skewered by a first linear chain molecule—in a manner so that the first circular molecule does not detach; the second polyrotaxane comprises second blocking groups being disposed at both ends of a second pseudo-polyrotaxane—formed from the opening of a second circular molecule being enclathrated by being skewered by a second linear chain molecule—in a manner so that the second circular molecule does not detach; said first and second polyrotaxane are formed from crosslinking with the first and second circular molecules therebetween; said material is solvent free; and the material has a dielectric constant at 1 kHz of at least 6.0.
