Resumo

The influence of ice-crystals growing direction over the organization of cellulose nanofibers as freezecasted foams is reported. This tuning was achieved by changing the metallic (copper) area of the sample molds which altered the freezing-front behavior, causing an oriented foam structure in certain directions. This orientation imparted different microarchitectures to the foams, leading to different pores sizes and wall thicknesses which could be characterized by advanced image techniques based on microtomography. As consequence, mechanical properties, such as compression modulus, have changed. In this study, a statistical approach is used to validate all the results obtained. (C) 2018 Elsevier B.V.
