한국어 초록
A fabrication method to improve the processability of thermoplastic carbon nanotube (CNT)mat composites was investigated by using in-situ polymerizable and low viscous cyclic
butylene terephthalate oligomers. The electrical conductivity of the CNT mat composites
strongly depended on the compression pressure, and the trend can be explained in terms of
two cases, low and high compression pressure, respectively. High CNT mat content in the
CNT mat composites and the surface of the CNT mat composites with fully contacted CNTs
was achieved under high compression pressure, and direct contact between four probes and
the surface of the CNT mat composites with fully contacted CNTs gave resistance of 2.1 Ω. In
this study the maximum electrical conductivity of the CNT mat composites, obtained under
a maximum applied compression pressure of 27 MPa, was 11 904 S m<SUP>-1</SUP>, where the weight
fraction of the CNT mat was 36.5%.
