preparation Embodiment 1-9

[0098] 2,4-Hexadiyn-1,6-diol (HDO) was added to 1 g of PEDOT:PSS aqueous solution (Sigma-Aldrich) including 0.5% by weight of PEDOT and 0.8% by weight of PSS as shown in Table 1, and ultrasonically It was fully dissolved for 10 minutes to obtain a mixed solution. The mixed solution was filtered using a 0.45 mm filter to remove impurities to obtain conductive ink compositions for optical micromachining according to Preparation Examples 1-9.

preparation Embodiment 1

[0106] One of the prepared conductive ink compositions was spin-coated on a glass substrate to obtain a uniform conductive film, and then dried to measure the conductivity of the conductive film. A photomask with a light-transmitting pattern is arranged on the conductive film, and the photomask is used as a mask to irradiate a wavelength of 254nm (12.5mWcm -2 ) of ultraviolet light for 10 seconds. After the UV exposure, the substrate with the conductive film was immersed in water to remove the portion not irradiated by UV, and then washed with ethanol to form a conductive pattern. Then, the conductive pattern was dried, and the conductivity of the dried conductive pattern was measured.

The conductive ink comprises a conductive polymer and a diacetylene diol monomer represented by the following Formula (1). [Formula 1] HO-Rn-C-triple bond-C-C-triple bond-C-Rm-OH. In Formula 1, n and m are independently 1 to 10, R is CRaRb or (CRaRb)xO, Ra and Rb are independently hydrogen or a halogen group, and x is an integer of 1 to 3. In Formula 1, R is CH2, and n and m may be independently an integer of 1 to 4.

Description

technical field [0001] The present invention relates to a conductive ink and a method of manufacturing a pattern using the same, and more particularly, to a conductive ink containing a conductive polymer and a method of manufacturing a pattern using the same. Background technique [0002] Generally, pixel electrodes applied to displays should be transparent electrodes, and should satisfy electrical and optical properties, such as 10 as electrical properties 3 Ω / sq or less sheet resistance and 10 -3 resistivity of Ωcm or less, and transmittance of 80% or more in the visible light region as optical properties. [0003] Transparent electrodes are applied to various fields such as organic light emitting diodes (OLEDs), solar cells, touch screens, and keypads of mobile phones, depending on conductivity. Research to replace ITO electrodes, which are conventional inorganic transparent electrode materials, is being actively conducted, and new electrode materials using metal thin f...
