摘要: Abstract Cellulose nanocrystals (CNCs) were released from bleached cotton and flax by a sulphuric acid hydrolysis with about 40 34% yield, respectively. The rod-like cotton-CNC particles slightly longer wider had less pronounced aggregation ability in aqueous suspension than the flax-CNC ones. Films cast CNC suspensions sorbitol glycerol plasticisers. concept behind this research was to explore how plasticisers – similar structure but different molecular weight their concentrations affect perceptible measured properties of films. Results revealed that type plasticiser determined morphology optical tensile best quality film an averaged thickness 50 μm obtained 20% cotton-CNC. It proved behaviour films very reported previously for starch
