Summary: | The present invention relates to a polar carbon nanotube dispersion capable of being dispersed in a solvent at high concentration, and a separator with improved filtering efficiency based on a polar carbon nanotube and a polar one-dimensional carbon body manufactured through the same. According to the separator and the manufacturing method of the present invention, a polar carbon nanotube dispersion capable of being dispersed in a solvent at high concentration without a use of surfactants or stabilizers is manufactured, and a separator that does not peel off easily and can be used stably even under high pressure can be manufactured based on a polar carbon nanotube and a polar one-dimensional carbon body manufactured through the same.
본 발명은 고농도로 용매에 분산이 가능한 극성 탄소나노튜브 분산액, 이를 통하여 제조된 극성 탄소나노튜브 및 극성 1차원 탄소체를 기반으로 하여 여과 효율이 향상된 분리막에 관한 것이다. 본 발명의 분리막 및 이의 제조방법에 따르면, 계면 활성제나 안정제의 사용 없이도 고농도로 용매에 분산이 가능한 극성 탄소나노튜브 분산액을 제조하고, 이를 통하여 제조된 극성 탄소나노튜브 및 극성 1차원 탄소체를 기반으로 하여 쉽게 박리되지 않고 고압에서도 안정적으로 사용 가능한 분리막을 제조할 수 있는 효과가 있다. |
