Effect of nanoporous confinement on the phase behaviour of aqueous solutions

纳米孔约束对水溶液相行为的影响

基本信息

项目摘要

The effects of nanoporous confinement on the fundamental properties of condensed matter are numerous. A general understanding of the phase behaviour, dynamic and transport properties of nanoconfined fluids has been acquired for the last two decades from abundant studies that have addressed different aspects such as the capillary condensation, freezing/melting, glassy dynamics, molecular diffusion and liquid imbibition. However, it is notorious that classical descriptions of pure (unary) confined fluids fail to capture entirely the upper level of complexity attained with multicomponent systems. For example, it was recently shown that classical thermodynamics, combining Gibbs-Thomson and Raoult’s laws fail to explain the experimental phase behaviour of binary nanoconfined solutions. In this context, the ultimate aim of the project is to elucidate and model the different phenomena that dictate the phase behaviour (vapor/liquid/glass/crystal) of aqueous solutions in nanoporous materials. This requires addressing important aspects, covering structure and dynamics that have played secondary role or that were simply not relevant for previous physical studies of unary confined liquids. Our project will benefit from carefully designed advanced porousmaterials that will be used as model systems to generate and control the in/homogeneous character of the confined phases. This will allow studying the effects of polydispersed porosity as obtained with hierarchical porous materials, or spatially modulated surface interactions as obtained with porous materials alternating hydrophobic/hydrophilic regions.Organic molecules, molecular ions and inorganic salts will be used as a panel of solutes with controllable size, polarizability and hydrophilic character.
纳米孔约束对凝聚态物质基本性质的影响是很多的。在过去的二十年中,通过对毛细管凝聚、冻结/融化、玻璃动力学、分子扩散和液体吸吮等不同方面的大量研究,人们对纳米流体的相行为、动力学和输运特性有了大致的了解。然而,众所周知的是,纯(单)受限流体的经典描述未能完全捕捉到多组分系统所达到的高级复杂性。例如,最近有研究表明,结合吉布斯-汤姆逊定律和拉乌尔定律的经典热力学不能解释二元纳米约束溶液的实验相行为。在这种情况下,该项目的最终目标是阐明和模拟纳米多孔材料中水溶液的相行为(蒸汽/液体/玻璃/晶体)的不同现象。这需要解决一些重要的方面,包括结构和动力学,这些方面起着次要的作用,或者与以前的单一受限液体的物理研究完全无关。我们的项目将受益于精心设计的先进多孔材料,这些材料将被用作模型系统,以产生和控制限制相的非均匀特性。这将允许研究多分散孔隙度的影响,如通过分层多孔材料获得,或空间调制表面相互作用,如通过多孔材料获得交替疏水/亲水性区域。有机分子、分子离子和无机盐将被用作具有可控尺寸、极化性和亲水性的溶质面板。
