Abstract: In this project, pseudo-poly(amino acid)s (PAAs) containing different amino acids in main chain were synthesized by direct polyesterification of N,N-(pyromellitoyl)-bis-D-4-hydroxyphenylglycine di-Me ester as biol. active diol with diacid monomer derived from different amino acids was carried by tosyl chloride/pyridine/DMF as condensing agent. All biol. properties of the polymers were determined by biol. evaluation in bacterial media. PAAs containing silver nanoparticles were fabricated by in- situ method using dimethylformaide (DMF) as a solvent which leads to a spontaneous reduce in room temperature Furthermore, these biopolymer nanocomposite/Ag thin films were immobilized on glass microbeads. The chem. structures of synthesized PAAs and PAA/Ag nanocomposite (NC) were considered by FTIR, 1H-NMR spectroscopy, transmission electron microscopy (TEM), elemental anal., differential scanning calorimetry (DSC), thermogravimetric anal. (TGA), SEM, and energy dispersive X-ray (EDAX). The results of EDAX and TEM anal. of PAAs/Ag NC showed that silver particles have homogeneous dispersion and uniformity in nano-dimensions about 50 nm in PAAs matrix. The micro glass beads were coated with PAA/Ag nanocomposite thin film and placed in a column through for the disinfecting effect of Escherichia coli in water was evaluated very well. The experimental process involved the reaction of H-Phg(4-OH)-OH(cas: 32462-30-9).SDS of cas: 32462-30-9
