metadata.conference.dc.description.abstract: Partially phosphorylated poly (viny alcohol) (PPVA) films were prepared by reaction of PVA with different mole ratio of phosphoric acid using solution casting technique. The thermal stability of PPVA films is increases upon the addition of phosphoric acid which prove the strong bonding between PPVA and phosphoric acid. A significant broadening effect in the X-Ray diffraction (XRD) pattern proves the maximum bonding between PVA and phosphoric acid at mole ration of 0.3. FTIR spectra the maximum bonding between PVA and phosphoric acid occurs in the PPVA sample at mole ration of 0.3. Raman spectra reveal notable variations in peak intensity, size and position of OH, P (OH)2 and C-O-P due to the interaction between phosphoric ions and PVA. Therefore, PPVA films with a mole ration of 0.3 produced optimum interaction between PVA and phosphoric acid.
