Abstract
In this study, chitosan-MgO bio-composite was successfully prepared by simple chemical precipitation method. The bioactive polymer of chitosan (N-deacetylated derivative of chitin) was subjected to action with magnesium oxide modifiers. The functional characteristics of chitosan and MgO were characterized and confirmed by FTIR spectroscopy. From the XRD pattern, crystalline pattern of CS-MgO composite was found to be the semi crystalline nature. The biopolymer connected MgO particles was in rod like structure and confirmed by H-SEM analysis. Thermal characteristics of MgO incorporated chitosan have higher stability than chitosan biopolymer. Thus the result of chitosan-MgO bio composite was demonstrated that the synergistic effect obtained among the two components. Consequently, antimicrobial activity of the components was performed against the microbial pathogens revealed that MgO modified chitosan acts as a better bacterial inhibition activity than MgO. Therefore, Chitosan-MgO bio-composite may be an expectant material for the biomedical applications.
