Study on Liquid Crystalline Orientation for Carbon Nanotubes
Abstract: The research on liquid crystallinity of carbon nanotubes (CNTs) is the novel and frontier subject. The liquid crystallinity is their orientation characteristic, which is from the effects of excluded volumes for CNTs and performs the typically optical birefringence. CNTs’ rodlike anisotropy lies in promoting formations of various orienting liquid crystalline defects and the nanotube uniform alignments, and the liquid crystalline defects will be expected to transform into highly uniform orienting structures with actions of doping, shearing, external fields and so on. The paper mainly makes simple reviews about orienting characteristics for liquid crystalline CNTs by means of morphology characterization, emphasizing their inherent properties. Magni-tudes of nanotubes make them visible under certain characterization (i.e. scanning electron microscopic characterization), as well as both of their inherent high Young’s modulus and the strong attractive interaction between them make the liquid crystallinity uncommon but regular (apt to behave splaying).
