Abstract:
The effect of nanostructured carbon-based materials with strategically functionalized surface in controlling the electron transport through the nanomaterial/cement interfaces was evaluated. 1D and 2D functionalized carbon nanotubes (CNTs), nanofibers (CNFs) and graphene nanoplatelets (GNPs) with different intrinsic conductivity were used. The Impedance, namely conductivity and reactance, of the carbon/cementitious material nanostructured interfaces were evaluated via measuring and mapping their nanometer current signal (nA). The characterization of the interface’s Impedance profile was used to define the optimum conductive network into the cementitious matrix, necessary to achieve a percolative-like behavior of the nanocomposites desired for novel, powerful functionalities.
