Abstract
Provided are a polymer and a polymer actuator including the polymer. The polymer is cross-linked by a cross-linking agent. When the polymer is used in the polymer actuator, the polymer actuator shows a high strain and may be stably operated at high temperatures.
Claims10
A polymer material comprising a poly vinylidene fluoride (PVDF)-based terpolymer that is cross-linked by cross-linking agent, wherein the PVDF-based terpolymer comprises:
- as a first structural unit, a vinylidene fluoride monomer;
- as a second structural unit, trifluoroethylene or tetrafluoroethylene;
- and
- as a third structural unit, vinyl fluoride, perfluoro (methyl vinyl ether), bromotrifluoroethylene, chlorofluoroethylene, chlorotrifluoroethylene, or hexafluoropropylene, and
- wherein the cross-linking agent comprises at least one selected from the group consisting of methylenediamine, ethylenediamine, N-isopropyl ethylenediamine, 1,3-phenylenediamine, 1,5-naphthalenediamine, and 2,4,4-trimethyl-1,6-hexanediamine.
