Wormlike Micellar Formation by Using Surfactant Derived From Renewable Resources
Accounts of Materials&Surface Research 2018.10 [Reviewed] [Invited]
Language：Japanese Publishing type：Article, review, commentary, editorial, etc. (other) Joint Work
Shape of surfactant micelles may change to spherical, rod-like, or wormlike micelle depending on the surfactant concentration in the aqueous solution and the hydrophilic-lipophilic balance. Wormlike micelles entangle like polymer chains and increase the viscosity of the solution. Solution viscosity may reach up to 10 million times the viscosity of water. In addition, such a thickened solution becomes a non-Newtonian viscoelastic body exhibiting thixotropy and a Maxwell-type relaxation behavior having a single relaxation time like a polymer solution. Unlike polymer, wormlike micelles, which are supramolecular assembly systems, has self-repairing ability against chain breaking due to mechanical disturbance by mechanical force, heat, light, etc. Because of these characteristics, wormlike micelles are used for viscosity control in detergents (e.g. shampoo) and cement as well as fluid transport by drag reduction (DR) effect. Petroleum-based surfactants are conventionally used in these applications, but the use of surfactants derived from renewable resources (bio-based surfactant) is demanded from the viewpoint of appeal to consumers as well as environmental problems. In this review, some examples of wormlike micelle formation from our studies are briefly described. Bio-based surfactants used are commercially-available ones such as acyl glutamate, sucrose fatty acid ester, polyoxyethylene cholesteryl ether in addition to a newly developed surfactant, isosorbide-based surfactant.Shape of surfactant micelles may change to spherical, rod-like, or wormlike micelle depending on the surfactant concentration in the aqueous solution and the hydrophilic-lipophilic balance.

界面活性剤の機能性は表界面への吸着と分子集合体形成による。界面活性剤の水中での濃度上昇とともにミセルやリオトロピック液晶が形成され，相平衡図中であらわすことが一般的である。界面活性剤濃厚系で形成されるリオトロピック液晶の構造はおもに界面活性剤の集合体中での充填形態によって決まる。非イオン界面活性剤であるポリ（オキシエチレン）アルキルエーテルではポリ（オキシエチレン）鎖の重合度を変化させると親水基間の反発力が変化しリオトロピック構造の変化が生じ，その構造変化は臨界充填パラメーターによって説明できる。リオトロピック液晶はメソ多孔体合成やDDSキャリアなどに用いることができる。また，希薄系で形成されるミセルの形状も親水基間の反発力に応じて変化する。とくにひも状ミセルと呼ばれる高分子鎖のように伸びたミセルは系の増粘をもたらし，DR剤や泡沫安定化剤などに利用される。
