摘要
Well-organized CNT-SiC hybrid structures were prepared by a floating catalytic chemical vapor deposition (CCVD) process. The aligned CNT-based composite materials were also fabricated by simply stretching. Gelatin and CNT-SiC hybrid structures were taken as the matrix and fillers, respectively. The alignment of CNT-SiC hybrids and anisotropic properties of the composite materials were discussed using the detection of THz time-domain spectroscopy technology. The results indicated that the anisotropic properties of CNT-SiC hybrid based composite films are better than the case of pure MWCNTs. The unique structure of the hybrids not only largely favors the dispersion of CNTs in a polymer matrix, but also favors the alignment of CNTs in the composites by stretching. The CNT-based composite films with further improvement in anisotropy are highly desirable for various modern applications in the electrical and optical industry (such as in polarizers).
