改性蒙脱土的制备及其协同海藻酸衍生物稳定Pickering乳液的研究
Preparation of modified montmorillonite and its function for stabilizing Pickering emulsions in cooperation with alginic acid derivative
摘要
Abstract
The intercalating modified montmorillonite(CMMT)was prepared by wet type ball mill process with montmorillonite(MMT)as basic material and hexadecyltrimethylammonium bromide(CTAB)as hydrophobic modifying agent.Then the product CMMT was characterized by SEM,zeta potential analyzer,FT-IR,XRD, TEM and TGA. Furthermore,stable Pickering emulsions were prepared by CMMT in cooperation with amphiphilic alginic acid derivative(Ugi -Alg),and then the effect of the CMMT that modified with varied amount of CTAB on the stability of Pickering emulsion was investigated. Experimental results show that the CTAB is intercalated into the lamella interlayers of MMT micro-particulates by the mechanical action of the ball mill.Ugi-Alg is adsorbed on surface of the CMMT,that enhancing the aggregation capacity of the CMMT particulates at the oil-water interface.When the addition amount of CTAB is 1.0CEC,the charge of CMMT particulates is at the lowest while the emulsion stability is the highest.关键词
