A turbid gel of CTAB in a binary solvent mixture at a critical composition was observed to be 1\u2009:\u20093 v\/v toluene\u2009:\u2009water. The molecular structure of the as-formed gel was investigated by X-ray diffraction and microscopic techniques, namely, optical and polarizing microscopy, scanning electron microscopy and small-angle X-ray scattering (SAXS). The phase evolution has been studied using UV\u2013visible transmittance measurements and the thermal characteristics of the gel by differential scanning calorimetry measurements. SAXS studies, in conjunction with molecular modelling, revealed the gel to assemble as lamellae with high interdigitation of bilayer assembly of CTAB molecules with predominant non-covalent interactions, where the gel lamellae were inferred from the interplanar spacings. Rheological studies revealed the viscoelastic nature of the CTAB gels. The ability to form a gel has been evaluated in several polar solvents, such as methanol and chloroform, and non-polar solvents, such as toluene and carbon tetrachloride.<\/jats:p>","DOI":"10.1098\/rsos.231487","type":"journal-article","created":{"date-parts":[[2024,4,3]],"date-time":"2024-04-03T01:12:21Z","timestamp":1712106741000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Solvent selective gelation of cetyltrimethylammonium bromide: structure, phase evolution and thermal characteristics"],"prefix":"10.1098","volume":"11","author":[{"given":"Chapireddy","family":"Nagarjuna","sequence":"first","affiliation":[{"name":"Department of Chemistry, School of Advanced Sciences, VIT-AP University , Amaravati, Andhra Pradesh 522 241, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6376-0539","authenticated-orcid":true,"given":"Illa","family":"Ramakanth","sequence":"additional","affiliation":[{"name":"Department of Chemistry, School of Advanced Sciences, VIT-AP University , Amaravati, Andhra Pradesh 522 241, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2024,4,3]]},"reference":[{"key":"e_1_3_8_2_2","doi-asserted-by":"publisher","DOI":"10.1039\/c2jm32123h"},{"key":"e_1_3_8_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/acsabm.9b00424"},{"key":"e_1_3_8_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.5b00190"},{"key":"e_1_3_8_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/la400805c"},{"key":"e_1_3_8_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar900282h"},{"key":"e_1_3_8_7_2","doi-asserted-by":"publisher","DOI":"10.1039\/C8QO00620B"},{"key":"e_1_3_8_8_2","doi-asserted-by":"publisher","DOI":"10.3390\/gels4020040"},{"key":"e_1_3_8_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11426-011-4295-x"},{"key":"e_1_3_8_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10847-013-0299-9"},{"key":"e_1_3_8_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetlet.2016.06.111"},{"key":"e_1_3_8_12_2","doi-asserted-by":"publisher","DOI":"10.1021\/la104333x"},{"key":"e_1_3_8_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/adhm.202001341"},{"key":"e_1_3_8_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.solmat.2019.110128"},{"key":"e_1_3_8_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.copbio.2013.02.006"},{"key":"e_1_3_8_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cclet.2017.04.033"},{"key":"e_1_3_8_17_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar0500923"},{"key":"e_1_3_8_18_2","doi-asserted-by":"publisher","DOI":"10.1039\/C2CS35436E"},{"key":"e_1_3_8_19_2","doi-asserted-by":"publisher","DOI":"10.1088\/0957-4484\/21\/22\/225606"},{"key":"e_1_3_8_20_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja046215g"},{"key":"e_1_3_8_21_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.macromol.1c00197"},{"key":"e_1_3_8_22_2","doi-asserted-by":"publisher","DOI":"10.1021\/la034772v"},{"key":"e_1_3_8_23_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm201913p"},{"key":"e_1_3_8_24_2","doi-asserted-by":"publisher","DOI":"10.1039\/b500837a"},{"key":"e_1_3_8_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.colsurfa.2014.11.051"},{"key":"e_1_3_8_26_2","doi-asserted-by":"publisher","DOI":"10.1039\/c1cc11428j"},{"key":"e_1_3_8_27_2","doi-asserted-by":"publisher","DOI":"10.1039\/b903407b"},{"key":"e_1_3_8_28_2","doi-asserted-by":"publisher","DOI":"10.1002\/masy.200650904"},{"key":"e_1_3_8_29_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chemosphere.2016.09.149"},{"key":"e_1_3_8_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apsb.2011.12.005"},{"key":"e_1_3_8_31_2","doi-asserted-by":"publisher","DOI":"10.1016\/0032-3861(79)90281-7"},{"key":"e_1_3_8_32_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.accounts.7b00070"},{"key":"e_1_3_8_33_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.elecom.2009.02.025"},{"key":"e_1_3_8_34_2","first-page":"7701","article-title":"Fabrication of cupric oxide-based transistors by a sol\u2013gel technique using a binary solvent mixture","volume":"33","author":"Vincze T","year":"2022","unstructured":"Vincze T , Micjan M , Pavuk M , Weis M . 2022 Fabrication of cupric oxide-based transistors by a sol\u2013gel technique using a binary solvent mixture.
