We prepared a typical worm-like micelle (WLM) system in 100 mM cetyltrimethylammonium bromide (CTAB)/70 mM sodium salicylate (NaSal), which showed high zero-shear viscosity (η0). Upon the addition of 20 mM 3-fluorophenylboronic acid (3FPBA) to the WLM system, η0 decreased by 1/300 that of the system without 3FPBA. Furthermore, upon the addition of 1.12 M fructose (Fru) and 1.12 M sorbitol (Sor) to the CTAB/NaSal/3FPBA system, η0 increased by 50-fold and 30-fold, respectively. 19F NMR spectral results of the systems using 4-fluorosalicylic acid (FSal) instead of NaSal demonstrated that the FSal/3FPBA-complex interacts with CTAB. Moreover, the addition of sugar or sugar alcohol to the micellar system leads to a decrease in the amount of FSal/3FPBA-complex interacting with CTA+ and an increase in the amount of 3FPBA/Fru or Sor-complex, which does not interact with CTA+. These changes in molecular interactions induce the elongation of the WLMs and increase the viscosity of the system. This system utilises the competitive cyclic ester bond between the NaSal/3FPBA and 3FPBA/sugar or sugar alcohol to induce viscosity changes.キーワードdiol-responsive/phenylboronic acid/smart material/viscosity increase/worm-like micelles/ジオール応答/フェニルボロン酸/スマート材料/粘性増加/紐状ミセル注記This article is licensed under a Creative Commons Attribution 3.0 Unported Licence.言語 eng資源タイプtextジャンル01学術雑誌論文 / Journal Articleフォーマットapplication/pdf権利Copyright © 2022 The Author(s).このアイテムを表示する：本文(pdf)( 982.4KB) ダウンロード回数： 回このアイテムを表示する：URIhttps://libir.josai.ac.jp/il/meta_pub/G0000284repository_JOS-d1ra08831aURL:G0000284repository_JOS-d1ra08831a  var xurl =document.URL; var xrecid = 'G0000284repository_JOS-d1ra08831a'; var xReg = new RegExp(/(.*meta.*\/)/); var xmatch = xurl.match(xReg); var urlstr = RegExp.$1; if( xmatch) jQuery('a#infolib_permalink').html( urlstr + xrecid ); detailcont["max"] = '0'; detailcont["detailViewFlg"] = '0'; var xswitchViewButton = jQuery('div#detailContentsSwicher'); xswitchViewButton.show(); var xEditorButton = jQuery('div#detailEditor'); if( xEditorButton.length) { xpanel.xEditorPrime = "JOS-d1ra08831a"; xEditorButton.show(); } detailcont["contentsDspMax"] = '5'; detailcont["show"] = 'all'; detailcont["contentsDbId"] = 'G0000284repository'; detailcont["currentContNo"] = '0'; meta.detailSetViewerHeight(); Copyright(C) 2010 Josai University.
