  • Patent number: 9150414
    Abstract: A nanocomposite comprises a nanostructure, and a copolymer adsorbed to the nanostructure and containing at least one ionic monomer unit and a different monomer unit from the ionic monomer unit; the ionic monomer unit selected from the group consisting of a zwitterionic monomer unit and a cationic monomer unit which are represented by the following formula (1): (in the formula (1), R1, R2, and R3 each independently represent any one of a hydrogen atom and a monovalent organic group having 1 to 20 carbon atoms, Y1 represents any one of a carbonyl group and an arylene group, Y2 represents any one of —O— and —NH—, n is 0 or 1, R4 represents a divalent organic group having 1 to 20 carbon atoms, and X represents any one of a zwitterionic group and a cationic group).

  • Patent number: 8859668
    Abstract: A resin composition comprises a carbon-based nanofiller (A), a modified polyolefin-based polymer (B), and two or more resins (C) other than the modified polyolefin-based polymer (B), the resin composition comprising a dispersed phase formed from a resin (Caff) which has a highest affinity for the carbon-based nanofiller (A) among the two or more resins (C), and a continuous phase formed from the remaining one or more resins (C1), wherein at least part of the modified polyolefin-based polymer (B) is present at an interface between the dispersed phase and the continuous phase, and the carbon-based nanofiller (A) is present in the dispersed phase.

  • Patent number: 7585910
    Abstract: A polylactic acid composition containing polylactic acid and ester-based plasticizer, wherein a content of the ester-based plasticizer is 16 to 33 wt %, and when the composition is highly deformed by stress loading as the relation between the stress and the deformation deviates from linear viscoelastic behavior and thereafter the stress is released, residual deformation measured after the stress is released is not less than 66.0% after 0.2 minute of the stress release, and is not more than 34.0% after 240 hours of the stress release.
