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...

The development of novel biomedical materials for practical and clinical applications, such as drug carriers, biocompatible tissue or organ substitute materials, repair and regeneration biomaterials, etc., is always a most concerned topic for biologists and material scientists. Many natural materials have been used as biomedical materials to replace traditional organic synthetic materials. More
