SÍNTESIS Y CARACTERIZACIÓN DE MATRICES ORGÁNICAS E INORGÁNICAS CONTENIENDO PIGMENTOS NATURALES
Abstract
This research work evaluates the embedding of carminic acid (AC) on hydroxyl-terminated oligostyrene matrixes (PSOH) and SiO2. It describes the characterization of thin films of PSOH/AC and SiO2/AC through scanning electron microscopy (SEM), Infrared and Raman spectroscopy. It shows that at concentrations below 0.2% by weight of AC it significantly favors integration and color films generated uniform and transparent. As a result of low molecular weight matrix Mw = 3800 hydroxyl terminated groups appears as an important factor for polymer-AC interactions, the study by FTIR presented shifts in the characteristic bands (3300 cm-1) for the PSOH. The results by SEM for the system SiO2/AC suggest that interactions of silanol groups with AC molecules are presentDownloads
