fabrication and analysis of a novel chitosan schiff base decorated on graphene oxide

In this study, the synthesis of a novel go@cs@sb nanocomposite is reported via the sonochemical method. to modify chitosan, it was reacted with (n, n'-bis (2-hydroxy acetophenone) ρ-phenylenediamine), which led to the formation of cs@sb. subsequently, cs@sb was combined with graphene oxide, resulting in an increased density of functional groups such as oh, cooh, and nitrogen-based donors. these functional groups significantly influence the chemical composition and physical properties. they increase non-covalent interactions, which play a significant role in material applications. the nanocomposite was characterized using ft-ir spectroscopy, sem, and xrd. additionally, tga-dta measurements were conducted to evaluate the thermal stability of the go@cs@sb material.
