Abstract
Composite films were sprayed from mixtures of water soluble hydroxypropyl methylcellulose (HPMC) and either nanofibrillated cellulose (NFC) or cellulose nanocrystals (CNC). Fiber diameter was similar for both nanocelluloses but fiber length was several μm for NFC and about 200 nm for CNC. Films were characterized for morphology, swelling, mass loss and transport properties. NFC-HPMC films swelled less than CNC-HPMC films; with a HPMC content of 20 wt% NFC-HPMC and CNC-HPMC films presented swelling of 7 and 75 g/g, respectively. The swelling strongly influenced water transport across the films, with slower transport for CNC-based materials compared to NFC-based m...
