Fig. shows micrographs of YSZ ice-templated scaffolds after the epoxy impregnation and centrifugation. Similarly to the PCL infiltrated samples, the epoxy is deposited onto the rough ceramic walls without filling the microporosity. How-ever, the epoxy is too viscous to be removed from the samples, which generates a clogged porosity in some parts of the sample. We investigated the effect of centrifugal speed on porosity (Table ). The porosity increases with the centrifugal speed (Fig. ). The infiltrated polymer is more easily removed from the sample as the centrifugal speed increases. It is thus a simple way to control the amount of polymer deposited into the porous ceramic scaffold. . We further explored the possibility to modify simultaneously crack initiation and propagation by infiltrating both polymers in two steps. First, the ceramic samples were infiltrated with epoxy with the procedure previously described. Second, the epoxy-YSZ porous composite was vacuum-infiltrated with a PCL solution. As we expected, the resultant microstructure exhibited an epoxy layer which does not bond with the ceramic scaffold, and a PCL coating on top of that (Fig. ).
