▎ 摘　　要

NOVELTY - Stretchable conductor useful in flexible display, stretchable battery, electronic skin and soft robot in field of non-substitutable action, comprises conductive microsphere with core-shell structure formed by taking high molecular elastomer as core and conductive filler as shell USE - The conductor is useful in flexible display, stretchable battery, electronic skin and soft robot in the field of non-substitutable action. ADVANTAGE - The conductor has high conductivity, high conductive under large strain maintaining and soft mechanical feature, and dense stacking structure having more excellent performance. The stretchable conductive conductor has excellent performance e.g. initial conductivity of 67185 S/cm, elongation at break of 602 %, and high elastic modulus under 1% strain of 0.53 MPa. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparation method of stretchable conductor; and preparation method of conductive microsphere.
