PURPOSE: A method for plating flat cables by using a conductive paste is provided to minimize the error rate of a flat cable by performing plating by supplying power with being coated with conductive paste. CONSTITUTION: A method for plating flat cables by using a conductive paste is as follows. First exposing units(110A,110B) formed in both ends of flat cable is coated to the conductive paste. A second exposing unit(120) is plated by supplying power to the first exposing unit which is coated with conductive paste when the second exposing unit is dipped in plating bath(300) filled with plating solution.

PURPOSE: A manufacturing method for a conductive polymer blend composition produces a multi-phased polymeric composition with improved conductivity, mechanical and thermal properties, etc. by mixing inherently conducting polymers with a polymeric deaggregating agent. CONSTITUTION: A manufacturing method for a conductive polymer blend composition comprises a step of making a molecular composite by mixing conductive polymers with a polymer deaggregating agent. The conductive polymer blend composition has the molecular composite of the conductive polymers and a polymer deaggregating agent having poly (alkylene carbonate), or copolymers or derivatives thereof. The weight ratio of the conductive polymer and the polymers deaggregating agent is 1:100-100:1.

본 발명은 새로운 비선형과학 중심구조 양이온 N-벤질 스틸바졸리움 및 음이온을 포함하는 비선형광학 결정에 관한 것이다. 본 발명에서 N-벤질 스틸바졸리움 양이온 중심구조는 비극성이고 굽은 모양의 N-벤질 그룹을 스틸바졸리움 그룹에 도입함으로써 높은 다이폴 모먼트에 의한 다이폴-다이폴 상호작용을 극복하여 높은 거시적 비선형 광학 특성을 보이며, 기존의 대칭성 N-알킬 스틸바졸리움 중심구조를 바탕으로 하는 비선형광학 결정에 비해 높은 물에 대한 안정성 및 손쉬운 결정 성장 등의 장점이 나타나 비선형광학 재료로서 유용하게 응용 될 수 있다.
