Optical, Functional Impact and Antimicrobial of Chitosan/Phosphosilicate/Al2O3 Nanosheets
A nanosheets containing chitosan (CS) and bioactive P 2 O 5 :SiO 2 /Al 2 O 3 were prepared by the sol–gel method. The nanosheets were characterized by XRD, FE-SEM, FT-IR and optical studies. FE-SEM displayed a nano-clustering and dense structure with promising morphology. The optical results reveal...
