  - COLLOIDS AND SURFACES A-PHYSICOCHEMICAL AND ENGINEERING ASPECTS - Rok 2016

  Mixtures of nonionic gemini surfactant S-10 (α,α′-[2,4,7,9-tetrametyl-5-decyne-4,7-diyl]bis[ω-hydroxy -polioxyetylene] with cationic alkyltrimethylammonium bromides of different alkyl chain length (RTAB) were investigated. Basing on surface tension measurements the cmc values and other adsorption parameters were found. The Clint, Rubing’s and Rosen theories were applied for evaluation of the synergistic effects in mixed films and...

  - COLLOIDS AND SURFACES A-PHYSICOCHEMICAL AND ENGINEERING ASPECTS - Rok 2016

  Mixtures of nonionic gemini surfactant S-10 ( α, α'-[2,4,7,9-tetrametyl-5-decyne-4,7-diyl]bis[ω-hydroxy -polioxyetylene] with anionic SRS (sodium alkylsulfates) and SRSO3 (sodium alkylsulfonates) of different alkyl chain length (from 10 to 14 carbon atoms) were investigated. Surface tension measurements were used to find the cmc values and other adsorption parameters. The Clint, Rubingh’s and Rosen theories were applied for evaluation...

• The effect of surfactants mixtures composition on wetting of different solid materials

  Publikacja

  - Rok 2012

  The wetting properties of surfactants mixtures were investigated. Three types of compounds were used: nonionic gemini α, α'-[2,4,7,9-tetramethyl-5-decyne-4,7-diyl]bis[ω-hydroxyl-olioxyethylene] (S-10), anionic sodium dodecyl sulphates (SDS) and cationic dodecyl trimethyl ammonium bromide (DTAB). The materials used in wetting experiments were steel and methyl polymethacrylate. These materials differ...

  Badanie zdolności zwilżających mieszanin niejonowego surfaktantu gemini S-10 z surfaktantami anionowymi CsDS (dodecylosiarczan cezu) i LiDS (dodecylosiarczan litu). Badane powierzchnie różniły się stopniem hydrofobowości (szkło, stal, polimetakrylan metylu). Niektóre mieszaniny wykazywały synergizm w procesie zwilżania.
