The above dry mix was hydrated with 70 ml of a 0.083N sodium citrate solution (pH 9.01, M.W. 294.10) and mixed to a uniform plastic mass. The mix was then treated as detailed for Examples 19-31. The recorded and averaged temperature profile of the heating structure is shown in FIG. ...
Results have shown that adding CF in combination with CNT substantially reduces the electrical resistivity and, in turn, improves the heating performance, as CFs further densify the electrically conductive network in the hydrated matrix; adding either CNT or CF alone was not an effective option to ...
