SELF-ESSEMBLY OF GLYCINE, SILVER NITRATE AND POLIVINYL ALCOHOL IN AQUEOUS SOLUTIONS
Self-assembly in the systems based on low-concentration aqueous solutions of glycine, silver nitrate and polyvinyl alcohol (PVA) is studied by means of dynamic light scattering (DLS), FTIR and UV spectroscopy. It is found out that the size of the aggregates formed due to self-assembly depends on composition and molar ratio of the initial components. FTIR spectroscopic analysis of the Gly-PVA films confirms intermolecular interactions between the amino acid and the polymer. It is established that an addition of PVA into the glycine-AgNO3 system leads to a decrease of the nanoaggregate size and an increase of the system stability over time.
