Overview of the CNTT/t-ZnO composite structure. a Schematic representation of the fabrication process showing the highly porous (93%) ceramic network consisting of pre-sintered tetrapodal shaped ZnO microparticles (V = 1.7 cm3) before and after CNT infiltration. By adding CNTs to the network self-entangled CNT networks are formed leading to a high mechanical reinforcement effect, similar to traditional bamboo lashing; b, c SEM images of the ceramic network coated with a homogenous layer of self-entangled carbon nanotubes; d Detail of the CNT network around ZnO tetrapod central joint; e Detail of CNT network around tetrapods junction; f, g High magnification SEM images showing that the CNTs form self-entangled layers on the ceramic template; h, i Self-entangled CNT layer on a broken tetrapod arm, revealing the thickness of the coated CNT layer.
