Preparation of chitin film
Debnáriková, Michaela ; Abdelrahman, Rasha (oponent) ; Abdellatif, Abdelmohsan (vedoucí práce)
The bachelor thesis deals with the extraction, purification, dissolution and preparation of film based on chitin/ polyvinyl alcohol (PVA). The pure chitin was fully characterized by different techniques like potentiometric titration, FT-IR, TGA, XRD, SEM and solid NMR. The solubility, purity of extracted chitin was investigated and evaluated by measuring the protein percent, rheology, and time need for dissolution. The chitin/PVA films were prepared using different ratio between chitin and PVA solution and film was prepared by casting method. The surface morphology, rheological and mechanical properties of the film were measured and evaluated.
