2018年1月4日 · In this paper, the physicochemical properties between sodium dodecylbenzenesulfonate (SDBS) and polyvinylpyrrolidone (PVP) in aqueous solutions were studied at 25 °C by Ubbelohde viscometer, conductivity analyzer, and fluorescence spectrophotometer.

2021年9月3日 · To study the impact of synergy effect of adding sodium dodecylbenzene sulfonate (SDBS) and/or polyvinylpyrrolidone (pvp) in the electrolyte on the microstructure of dendritic copper powder, will provide reference to the control of micro morphology of dendritic copper powder as well as process improvement.

2023年8月20日 · The formation of the PVP–SDBS pseudo-polyanions is dominated by the unique cation-bridging effects among negatively charged PVP-bound SDBS micelles and positively charged bridging cations (Na +) and electronegative elements of PVP chains.

The mixed dispersant of polyvinylpyrrolidone (PVP) and sodium dodecylbenzene sulfonate (SDBS) exhibits superior dispersibility compared to the use of individual dispersants, which is due to the synergistic between the non-ionic polymer PVP and the anionic surfactant SDBS.

2019年6月4日 · The results showed that uniform and size-controllable capsules were synthesized by synergistic function of SDBS and PVP. Characteristics of capsule were studied by optical microscopy, Fourier transform infrared spectrometry, scanning electron microscopy, thermal gravimetric analysis, and 1 H NMR.

通过粘度、电导及表面张力研究了聚乙烯基吡咯烷酮（PVP）与十二烷基苯磺酸钠（SDBS）的相互作用，当cac（临界聚集浓度）<CSDBS<cac2（第二临界聚集浓度）时，SDBS主要通过负电性的离子头基与PVP带有部分正电的侧基之间的静电相互作用以单体形式与PVP链缔合，而 ...

The binding of sodium dodecyl benzene sulphonate (SDBS) with poly (N-vinyl-2-pyrrolidone) (PVP) has been investigated at 303.15 and 313.15 K using equilibrium dialysis, surface tension, viscosity, ultrasound velocity and ultrasound absorption techniques. From each of these studies four distinct regions of SDBS-PVP interactions were observed.

1999年12月1日 · Our microcalorimetric study deals with the interaction between poly (vinylpyrrolidone) (PVP) and sodium dodecylbenzenesulphonate (SDBS). Titrations are carried out at different temperatures and different polymer and electrolyte concentrations to obtain insight into the interaction mechanisms.

2004年3月15日 · It has been shown that the introduction of poly (N -vinyl-1-pyrrolidone) (PVP) in anionic surfactant solution leads to the formation of anionic surfactant–PVP superstructures, which can be exploited as confined crystallization environment [10].

SDBS is an anionic surfactant that produces dodecylbenzene sulfonate ions and Na+ in the solution, while PVP is a water-soluble polymer, both of which contribute to the uniformity of ions dispersion in the solution during the electrolysis process and prevent overlap.
