AI Article Synopsis
- The study examined how the optical properties of fluorinated poly(1,3,4-oxadiazole-ether)s are affected by the presence of SnO2, NiO, and SnO2/NiO mixed-oxide nanoparticles.
- Using UV-Vis absorption and fluorescence spectroscopy, it was found that the nanoparticles altered the absorption and fluorescence signals of the polymers.
- The research indicated a weak interaction between the metal oxide nanoparticles and the polymers, as evidenced by moderate Stern-Volmer quenching constants and a non-linear Scott plot trend, while also discussing the solvation behavior of the polymers in specific solvent mixtures.
Article Abstract
Optical characteristics of some fluorinated poly(1,3,4-oxadiazole-ether)s in presence of SnO2, NiO and SnO2/NiO mixed-oxide nanoparticles (NPs) was investigated. The interactions between polymers and metal oxide NPs were studied by steady-state UV-Vis absorption and fluorescence spectroscopy techniques. The absorption and fluorescence signals of all investigated polymers was modified by presence of both pure and mixed-oxide nanoparticles. The moderate values of Stern-Volmer quenching constant and non-linear trend of Scott plot indicate the less affinity between metal oxide NPs and polymers. The solvation behavior of some fluorinated poly(1,3,4-oxadiazole-ether)s in chloroform-N,N-dimethylformamide and N,N-dimethylformamide-dimethylsulfoxide mixtures was discussed.
