Raman analysis of polymerization of APST molecule

In this work we investigated the solidification of aminopropylsilanetriol dissolved in water (~25%) under different conditions by Raman spectroscopy. The solidification was carried out at three different temperatures 8 0C, 23 0C and 60 0C. The influence of electromagnetic radiation on the polymerization process was also studied. Samples were held to solidify in dark and at UV (254 nm and 356nm) spectral range. In order to investigate the influence of the substrate on the resulting polymer structure, teflon, PVC, glass, brass and silica were used. Best ordered polymerized structure was achieved for samples deposited on plastics and solidified in dark, at room temperature.
