Ordered Self-assembly of Gemini Molecules in Mesoporous Silica Channels Constructing Normal Micelles to Assist the Migration of OH-†
摘要
Abstract
Using assembly properties of Gemini surfactants[ maleic alkylene group diethyl bis( octyl dimethyl chloro/bromide) , abbreviated as G8-2-8 ] , the normal wormlike micelles, on which were full of quaternary ammonium groups, were orderly assembled in the mesoporous silica channels by the induction of sodium salicylate( NaSal) . The above mentioned normal wormlike micelles and the Si hydroxyl groups, which were in the inner wall of the porous silicon, function together as annular water chambers to construct the orderly and efficient transmission channels of OH-. The study of the G8-2-8/NaSal micelle systems’ rheological properties suggested that the G8-2-8/NaSal micelle network systems have been formed. Under the same experimental condi-tions, the formation process of G8-2-8/NaSal micelle network systems was introduced into polysulfone system to prepare the high alkaline-resistant anion exchange membranes, which with orderly, efficient OH-transmission channels. The characterization results indicated that ion conductivities, water uptake and ion exchange capaci-ty showed a rising trend with the increasing mass fraction of G8-2-8, especially under the condition which the ion exchange capacity and water uptake were not highlevel, but the migration efficiency of OH-had improved sig-nificantly. The 400 h high temperature alkaline-resistant test indicated that the largest decline of ion conducti-vity was only round about 1. 5%, and no obvious changes on morphology, which showed excellent alkaline resistance stability.关键词
