Rod reversed micelles with mixtures of optimized surfactants and hydrotropes

Contrast variation SANS will be used to study structures of reversed micelles in cyclohexane, and in particular to reveal effects of hydrotrope addition for promotion and growth of cylindrical micellar aggregates. This equilibrium study represents the first stage of a broader project, which will involve future high pressure/temperature and shear SANS experiments, aimed at understanding the recently discovered role of reversed micelles in lubricants. This is the first stage in a new 3.5-year PhD program to develop optimized lubricant fluids, and Georgina Moody is a 1st year PhD student, fully funded by Infineum.

本研究将采用对比度可变小角中子散射（Contrast variation SANS）技术，探究环己烷中反胶束的微观结构，重点揭示水溶助长剂的添加对圆柱形胶束聚集体的形成与生长的调控作用。本次平衡态研究为一项更宏大研究项目的第一阶段，后续将开展高压/高温及剪切场下的小角中子散射实验，旨在阐明反胶束在润滑油中近年新发现的作用机制。本项目属于一项为期3.5年的全新博士生培养计划的首个阶段，该计划旨在开发优化型润滑油流体，项目参与者乔治娜·穆迪（Georgina Moody）为一年级博士生，其研究全额由润英联（Infineum）资助。
