Abstract: Proposed is a laterally multilayered dielectric elastomer actuator and a method of manufacturing the same. The actuator includes a polymer frame, an electrode, and a dielectric elastic portion. The polymer frame includes a first pattern with a first comb shape of a predetermined thickness and a second pattern with a second comb shape of a predetermined thickness. The electrode includes a first electrode formed on a portion of the first pattern and a second electrode formed on a portion of the second pattern. The dielectric elastic portion is interposed between the first electrode and the second electrode and contains a dielectric elastomer. Since the actuators can be laterally stacked, a multilayered actuator in which a large number (several to several thousands) of dielectric elastomer actuators stacked can be manufactured in the form of a very thin film (<50 ?m).

Abstract: Disclosed are polyethylene, chlorinated polyethylene thereof and a molded article produced from the chlorinated polyethylene. More specifically, disclosed are polyethylene for preparation of chlorinated polyethylene, the polyethylene having a molecular weight distribution (MWD) of 5 or less, a melting index (5.0 kg) of 0.1 to 10 dg/min, a weight average molecular weight of 50,000 to 300,000 g/mol, a melting temperature of 125 to 135° C., a wax content of 0.0001 to 3% by weight or 0.01 to 0.3% by weight and a density of 0.94 g/cm3 or more, chlorinated polyethylene thereof and a molded article produced from the chlorinated polyethylene.
