Abstract：

The　rheological　behavior　of　the　aqueous　solutions　of　mixed　sulfate　gemini　surfactant　with　no　spacer　group,　referred　to　as　d-C　12S,　and　dodecyltrimethylammonium　bromide　(C　12TABr)　at　a　total　concentration　of　100　mmol•L　-1　but　different　molar　ratios　of　C　12TABr　to　d-C　12S　(α　1)　was　investigated　using　steady　rate　and　frequency　sweep　measurements.　The　wormlike　micelles　were　formed　over　a　narrow　α　1　range　of　0.20-0.27.　The　viscoelastic　solutions　exhibited　Maxwell　fluid　behavior.　At　the　optimum　molar　ratio　of　0.25,　the　zero-shear　viscosity　was　as　high　as　600　Pa•s　and　the　length　of　the　mixed　wormlike　micelle　was　about　0.45-0.85　μm.　The　present　result　provides　an　example　to　construct　long　wormlike　micelles　by　anionic　gemini　surfactant.　©　2011　SIOC,　CAS,　Shanghai,　&　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
