Materials World Network to Study Liquid Precursor Formation and Crystallization at Interfaces: Fundamentals towards Applications

所谓的聚合物诱导液体前体（PILP）相形成的基本方面将被探索。PILP相具有面向先进材料的仿生合成策略的潜力，似乎广泛适用于一系列无机和有机材料。然而，人们对其形成的基本物理化学参数、性质和向具有复杂形态的晶体的转变机制尚不清楚。根据项目合作伙伴的专业知识，制定了三个重点：1)PILP形成的基本原理：利用微量热法、超离心法和原位化学滴定法研究PILP形成的基本热力学和动力学，并制定有机PILP的三元相图。2)界面固定化：应开发一种固定化和稳定不稳定的PILP的技术，用于液相流变学和光谱分析及其结晶。3)界面上PILP相的调制：研究具有明确表面化学和结构的Langmuir和自组装单层对前驱体相转变的影响。

Fundamental aspects of the formation of so called Polymer Induced Liquid Precursors (PILP) phases shall be explored. PILP phases have the potential for biomimetic synthesis strategies towards advanced materials and seem to be broadly applicable for a range of inorganic as well as organic materials. Nevertheless, the fundamental physicochemical parameters of formation, properties and transformation mechanisms of PILP’s to crystals with complex morphology are not understood.Corresponding to the expertise of the project partners, three thrusts are formulated:1) Basic principles of PILP formation: The fundamental thermodynamics and kinetics of PILP formation shall be studied with microcalorimetry, Ultracentrifugation and in situ chemical titrations as well as the formulation of ternary phase diagrams for organic PILP’s.2) Immobilisation of PILP’s at interfaces: A technique shall be developed for immobilization and stabilization of the labile PILP’s for rheological and spectroscopical analysis of the liquid phases as well as their crystallization.3) Modulation of PILP phases at interfaces: The influence of Langmuir and self assembled monolayers with well defined surface chemistry and structure on the transformation of the precursor phase shall be investigated.
