Preparation and characterization of some composite phosphate glass-Polyaniline derivatives studying their antimicrobial activity

The present work involved the preparation of mixed composite derivatives from phosphate glass and polyaniline together with additional doped samples containing increasing CuO or ZnO (3→10 mol%). All prepared pure their composites were characterized by structural FTIR analysis, X-ray diffraction examinations surface scanning electron microscope (SEM). Further antimicrobial properties base glass, one two dopants (CuO,ZnO) studied evaluated. FT infrared spectrum undoped revealed vibrational bands due to PO4 tetrahedral groups which are extended 400 cm-1 1500 within mid region. exhibits characteristic for vibrations C – C, C- H, = N H groupings.

On other hand, peaks correlated components polymerized granular texture (PANI). SEM investigations mostly parent its exhibited in different forms. Glass varying responses micro-organisms. In general, favourable data.
