Morphology and Strength Characteristics of Composites Based on Nanocrystalline Cellulose and Water-Soluble Polymers

The effect of nanocrystalline cellulose (NCC) content on the morphology and strength characteristics of its composites with poly(ethylene oxide) (PEO), polyvinylpyrrolidone (PVP), and their mixture is studied. The miscibility of PEO and PVP improves if NCC is added. Scanning electron microscopy images showed that rearrangement of PEO crystalline regions and sorption of PVP on NCC particles improves the homogeneity of the composite structure and improves the strength characteristics.
