Polyvinyl Alcohol Conjugates: A Smart Materials. Advance Modification Methods

      Аннотация: This books involved the detail information about PVA conjugates. Synthesis, characterization of doped modified polyvinyl alcohol conjugates was studied by using casting method. Characterizations of DMPVA were carried out by using diffrent method It showed that, for DMPVAs amorphous nature result in greater ion diffusivity with high ionic conductivty.The electrical properties modified polyvinyl alcohol conjugates and doped modified polyvinyl alcohol samples were studied. The electrical conductivity of all the MPVA and DMPVA show a tendency to increase by increasing the temperature upto 403 K and obeys log ? vs. 1/T relation indicating their semiconducting behavior.The Fluorescence properties remodeled polyvinyl alcohol complexes with transition metal ions were studied. It can be seen that the emission peaks are at the same spectral position in RPVA and different spectral position in CRPVA.The magnetic properties modified polyvinyl alcohol conjugates and doped modified polyvinyl alcohol samples were studied. The magnetic property of the MPVAs and DMPVAs reveals that the magnetic properties of the metals ions are completely retained in the DMPVAs.
