Chitosan is the product when partially deacetylated chitin dissolves in dilute acetic acid. As such, depending on the degree of deacetylation, the carbonyl, C O NHR band can be observed at ∼1670 cm and the amine, NH band at 1590 cm. When lithium triflate is added to chitosan to form ...

It is shown that the interaction of amino groups and primary hydroxyl groups of chitosan with local charges on the surfaces of montmorillonite nanoparticles is responsible for a change in the system of intramolecular and intermolecular hydrogen bonds that is typical for polysaccharides. The glass-...
The current research aims to determine the impact of orange peel dye (OPD), an eco-friendly addition, on the optical properties of biodegradable polymers. This study investigates the enhancement of optical properties in solid electrolytes based on chitosan (CS) and glycerol, with varying OPD ...
As in other polymer blends, the phase behavior of silk fibroin (SF) blends with other polymers is thought to be important for their related properties. Here we used FTIR imaging to study the phase behavior of three silk protein-based polymer blends, silk fibroin/chitosan (SF/CS) blend, silk...
