제목 Fabrication of high performance carbon nanotube fiber
초록 Carbon Nanotube fiber (CNTF) is one of the promissing Carbon Nanotube (CNT) assemblies which can trasnlate remarkable properties of individual CNTs into macroscopic strcture. Typical methods for producing CNTF include forest spinning, surfactant-based coagulation spinning, direct spinning and liquid crystalline (LC) spinning. Unfortunately, property of CNTF to date shows just a few percent of that of idividual CNTs because many of developed techniques have thier own limitations and sometimes mutually incompatible. In this talk, the current progress of CNT fiber fabrication methods including LC spinning and direct spinning at KIST will be introduced. In addition, for the first time, we demonstrate novel technique which combines LC spinning with the direct spinning method to fabricate ultralight/strong (4.4 N/tex) and highly conductive (3> MS/min) CNTFs within one-minute processing time.
