my.unikl.ir-102392015-05-28T01:51:37Z Effect of Phosphoric Acid Concentration on the Optical Properties of Partially Phosphorylated PVA Complexes Asmalina Mohamed Saat Mohd Rafie Johan (UniKL MIMET) Full text article also available at http://www.hindawi.com/journals/ijps/2014/495875/cta/ Partially phosphorylated polyvinyl alcohol (PPVA) films were prepared at five mole ratios of phosphoric acid (PA) using solution casting technique. The optical properties of the PPVA films were examined using UV-visible (UV) and photoluminescence (PL) spectroscopy. The UV absorption spectra reveal that the absorption peaks are blue-shifted with an increase in PA concentration added to the pure PVA. The PL spectra show the presence of peaks which are characteristic of isotactic (389–398, 460–462 nm), syndiotactic (418–420 nm), and atactic (440–446 nm) configurations of the PPVA. The results also show the peak of O–P–O bonding at a wavelength range of 481–489 nm. 2015-05-28T01:48:35Z 2015-05-28T01:48:35Z 2014 Asmalina Mohamed Saat and Mohd Rafie Johan, “Effect of Phosphoric Acid Concentration on the Optical Properties of Partially Phosphorylated PVA Complexes,” International Journal of Polymer Science, vol. 2014, Article ID 495875, 8 pages, 2014. doi:10.1155/2014/495875 http://localhost/xmlui/handle/123456789/10239 Hindawi |
