The present studies are focused on the effect of different polymer solutions, e.g. chitosan and polyvinyl alcohol (PVA) on the mechanical properties of the paper sheets. The improvement in the mechanical properties of the treated paper sheets with chitosan is higher than that in the other polymer solution. Moreover, the heat resistance of treated paper sheet with chitosan is more improved than with...
The α-form of the biopolymer chitin, with particle sizes in the 80-200 mesh range was deacetylated under hot alkaline conditions to yield chitosan. These biopolymers were characterized by nitrogen elemental analyses, infrared spectroscopy, X-ray diffractometry and carbon-13 NMR. The degree of deacetylation found was 80.5%, which was determined via infrared spectroscopy. Chitosan suspended in water...
