Abstract: Disclosed is a method of forming a conductive polymer thin film pattern, including (a) Coating substrate with solution including PEDOT:PSS (poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)) to form coating layer including solution on substrate, (b) irradiating a predetermined portion of the coating layer with light, thus manufacturing a pre-patterned substrate including PEDOT:PSS patterned on the predetermined portion and the coating layer other than the predetermined portion, and (c) removing the coating layer from the pre-patterned substrate, thus manufacturing a conductive polymer thin film having a PEDOT:PSS pattern. When the pattern formation method of the invention is applied, a pattern can be formed by directly irradiating a PEDOT:PSS solution with a laser, there is no need for additional drying, thus simplifying the processing and reducing the processing time, and a thin film for use in a transparent electrode can be manufactured, thereby improving the conductivity, transmittance, flatness and precision of the electrode.

Abstract: Provided is a method of manufacturing high strength synthetic fibers, and high strength synthetic fibers manufactured using the same. More particularly, the method involves a localized heating process by raising the temperature of a molten spinning fiber to a temperature higher than that of a pack body during a short period of time with no degradation through a heating zone located in the immediate vicinity of capillary in the spinning nozzle, so as to effectively control the molecular entanglement structure in the molten polymer without reducing the molecular weight and thus to enhance the drawability of the as-spun fibers, thereby improving the mechanical properties of the as-spun fibers, such as strength, elongation, etc., using the existing processes of melt spinning and drawing and thus enabling a mass production of a high-performance fiber at low cost.
