Novel interconnected PVA-based hydrogels with controlled porous structure prepared by freezing/thawing and porogen technique are presented in this study. Three types of poly(ethylene glycol) (PEG), with various molecular weights, have been used as porogens. Cellulose nanofiber (CNF) was incorporated...
