Abstract
The paper obtained during the study was mainly obtained from wheat straw cellulose and Jerusalem artichoke cellulose, which contained chitosan of various concentrations. An increase in the mechanical properties of the obtained papers was observed in samples using the substance chitosan. A 1.0% chitosan was added to the paper, mainly based on various plant celluloses. It should be noted that the obtained paper products were used without bleaching due to the fact that it was recommended to use them for wrapping paper. The youngest results were observed in samples prepared from a composition of wheat straw and artichoke pulp. From the fiber morphology, it was observed that the sized paper fibers became stronger, denser and smoother. Keywords: chytazone, Natural polymers, fibers, cellulose. Biocomposites of chitosan (CS)/cellulose nanocrystals (CN) were prepared by using solution casting method. Influences of solution preparation method and CN content on the properties of composites were investigated. Mechanical stirring/ultrasonication or micro fluidization were used to disperse nanocrystals in the chitosan matrix. The prepared nanocomposites were characterized by FTIR, XRD, SEM, DSC, TGA, TMA and contact angle measurements.
