Sintered ice-templated bars were infiltrated with two different polymers, polycaprolactone (Polycaprolactone Aldrich 440744-500G, M n = 80,000 g/mol, Sigma-Aldrich) or epoxy (Epotek 301, Billerica, Massachussetts, USA). The PCL infiltration process consisted in the preparation of PCL solutions with different concentration (4 and 8 wt.%) in ethyl acetate (anhydrous, 99.8%, Sigma-Aldrich) at 80 • C. Afterwards, the specimens were placed in a PTFE mold and the PCL solution poured on it. The process was performed under vacuum to facilitate the infiltration and removal of the residual air entrapped in the samples. After 20 min of vacuum infiltration the samples were placed on an absorbent paper for 24 hrs to ensure the entire evaporation of the solvent. Infiltration with epoxy was performed following a similar procedure: a mix of resin and hardener (80-20 wt.% respectively) was poured under vacuum in a PTFE mold with the ice-templated bars on it. Afterwards, the excess of epoxy was removed from the samples using a tabletop centrifuge at different centrifugal speeds (2500, 5000, 7500, and 10000 rpm).
