Abstract: This work developed a novel approach to prepare the CNTs/CNRs mixed nanomaterials by nanocasting method with tuning HNTs/PVA proportion, which employed HNTs as template and PVA as carbon source. We explored the effect of HNTs/PVA proportion on the structure of the mixed carbon nanomaterials. A series of characterizations, such as XRD, FTIR, Raman, N2 adsorption-desorption, TEM, SEM, resistivity and dispersibility, were used to determine the structure of the CNTs/CNRs mixed nanomaterials. The results found that PVA nanocasting content in the hollow nanostructure of HNTs affected the increase of CNRs in the CNTs/CNRs mixed nanomaterials. Upon the mass proportion of PVA/HNTs up to 1:1, the pore volume of the CNTs/CNRs mixed nanomaterials approached to the maximum of 2.142 cm3·g-1 and the specific surface area was up to 583 m2·g-1, and definitely showed a better conductivity and dispersibility, demonstrating that a lower PVA nanocasting content in HNTs could fulfilled a higher CNTs content in the CNTs/CNRs mixed nanomaterials. |
