Obtaining of Chitosan/ZNAL_1,9EU_0,05O₄ Film for Application as Biomaterial

Abstract:

This work reports the development and characterization by SEM, XRD, FTIR, emission and excitation chisonan/ZnAl₁_.₉Eu₀_.₀₅O₄ films with a mass proportion of 1:1. The powders were deagglomerated and passed 325 mesh screens and added to the diluted chitosan in 1% acetic acid. The materials were filtered and placed in petri dishes and placed in an oven at 60°C for solvent evaporation. After drying the film, a solution of 1M sodium hydroxide was added in order to obtain a film with neutral pH. With the XRD, it has been verified that the chitosan/ZnAl_1.9Eu_0.₀₅O₄ films presented the chitosan peaks and ZnAl₂O₄. Through the SEM, it has been observed that the chitosan/ZnAl_1.9Eu_0.₀₅O₄ presented a protruding surface. The results presented in emission and excitation spectra suggest that the film chitosan/ ZnAl₁_.₉Eu₀_.₀₅O₄ exhibit good luminescence properties, and are promising to be applied as a luminescent marker in future applications in the field of biomaterials.
