文摘
- •
Cellulose nanofibril (NFC) foams with various structural and mechanical properties were fabricated using cryodesiccation.
- •
Two solidification techniques of NFC suspensions were used: direct quenching and mechanical stirring followed by quenching.
- •
Solidification, type and concentration of NFC suspensions affected both foam microstructure and mechanical performances.
- •
3D X-ray microtomography images of in situ compression experiment unveiled the deformation mechanisms of foam cells.
