Title:
POLYMER ACTUATOR, CATHETER CONTAINING SAME, AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/093542
Kind Code:
A1
Abstract:
The present invention relates to a polymer actuator comprising: (i) a column-shaped electroactive polymer laminate; and (ii) a plurality of electrode coating layers present on a part of the surface of the column-shaped laminate, and a catheter containing the polymer actuator. The polymer actuator has low density and improved mechanical properties such as driving displacement, driving force and the like and response velocity, and driving characteristics can be controlled by controlling factors such as the ion exchange function of ionic groups present in an electroactive polymer, the number of the ionic groups, the distribution of the ionic groups, the type of coutercations, the thickness of an ion exchange membrane, the thickness of a surface electrode and the like, thereby enabling a catheter containing the same to be easily used as a guide wire or an active catheter.
