| Summary: | 碩士 === 國立成功大學 === 化學工程學系碩博士班 === 101 === The interaction between poly(N-vinylpyrrolidone) (PVP) and sodium dodecyl sulfate (SDS) has been investigated for many years. Due to the fact that quaternary ammonium salt has the hydrophobic property which is similar to SDS. Therefore, we add tetramethylammonium bromide(TMAB) and tetrabutylammonium bromide(TBAB) to research how do these salt influence the interaction between PVP and SDS.
In this study, we use the multi-angle laser light scattering with batch mode and gel permeation chromatography with online multi-angle laser light scattering, differential refractometer, and UV/Visible detector. Using this technique with the application of Hummel-Dreyer method and multi-component light scattering principle, we can get information about the binding ratio (the amount of SDS bound to PVP), the z-average radius of gyration (Rz), the molecular mass of PNVF/SDS/TAAB complexes (Mw,PS), and the conformation plot to infer the structure of the complex.
