The aim of this project is to develop, validate, and demonstrate a methodology for high-throughput mapping of the stability and structural evolution of complex polymer mixtures. Our motivation lies in formulation science which makes ubiquitous use of multicomponent mixtures whose comprehensive characterisation with conventional techniques is unfeasible. The project will involve three major tasks: (i) Creation of multicomponent discrete polymer libraries; (ii) Implementation of optical screening tools (turbidity and scattering) and automated data analysis; and (iii) Undertaking comprehensive experimental studies of two outstanding problems in polymer mixture thermodynamics, namely the effects of model block copolymer and nanoparticles on the phase behaviour and separation dynamics. A dedicated PhD student will work on the project along with the principal investigator; the project duration will be 36 months and the funding requested from EPSRC is 119,990. This proposal is submitted under the First Grant scheme.

该项目的目的是开发，验证和演示复杂聚合物混合物的稳定性和结构演变的高通量映射方法。我们的动机在于配方科学，它使普遍使用的多组分混合物的全面表征与传统技术是不可行的。该项目将涉及三项主要任务：㈠创建多组分离散聚合物库; ㈡采用光学筛选工具（浊度和散射）和自动数据分析; ㈢对聚合物混合物热力学中两个突出问题进行全面实验研究，即模型嵌段共聚物和纳米颗粒对相行为和分离动力学的影响。一名专门的博士生将与主要研究者沿着从事该项目;该项目为期36个月，要求EPSRC提供119，990美元的资金。这份提案是根据第一批赠款计划提交的。
