Abstract
One of the key issues for the development of high toughness carbon nanotube (CNT)reinforced composites is the control of the interfacial bond between the CNT and the matrix.Here, we introduce a novel technique to facilitate the homogeneous coating of single-walledcarbon nanotube (SWCNT) bundles with polycarbosilane (PCS)-derived SiC nanoparticles.The PCS dissolved in n-hexane was used as a precursor for SiC nanoparticles. Theresults obtained from XRD, TEM and EDXS analyses confirmed the formation ofβ-SiC nanoparticles of about 20 nm in diameter, which possessed a relatively homogeneousdistribution on the SWCNT bundles. It was shown that the number of SiC nanoparticlesper unit of SWCNT surface area could be adjusted by changing the weight ratio of PCSand SWCNTs. This approach may provide a useful route for the preparation ofSiC/SWCNT nanocomposites that have a tunable interface property with the matrix andpotentially with an enhanced anchor effect, which may have potential applications as areinforcing element in CNT/ceramic composites.
