Development and Application of Functional Hybrid Composite Materials

金属-有机骨架（MOFs）和杂化有机无机钙钛矿（HOIP）都是近年来引起越来越多兴趣的杂化材料（含有有机和无机组分的材料）。从历史上看，对这些类型材料的研究主要集中在其结晶形式上，直到最近，研究表明，它们的无定形和玻璃态也可以通过一系列方法获得，包括但不限于熔融淬火和机械化学方法。这些发现导致了一种新的玻璃材料的引入，混合玻璃，它介于无机玻璃和有机玻璃之间。虽然这些材料根据定义是无定形的，但研究表明，短程有序仍然可以保留，这表明在结构转变期间可以延续结晶形式所具有的性质。材料化学的这一新领域在气体储存和分离、催化和光学应用方面提供了可能的应用。尽管玻璃化学领域本身就具有多种应用，但通过考虑玻璃的复合材料，可以开发出更广泛、更多样化的材料。与其他固态材料。仔细选择组成这些复合材料的组成部分的类型和数量，可以引入很大程度的控制，从而能够定制基础化学和特定材料性能，以更好地满足目标应用。本项目的目的是研究基于混合玻璃的复合材料的合成和性能。复合材料的形成和由此产生的材料特性的性质将通过创建各种各样的复合材料，如玻璃陶瓷类似物和玻璃碳复合材料进行探索。衍射技术和热分析方法，如粉末X射线衍射（PXRD）;差示扫描量热法（DSC）;和热重分析（TGA）将用于研究玻璃及其复合材料的初始形成。一旦形成，将通过使用气体吸附和压痕等技术来探测材料的整体特性，目的是确定潜在的未来应用。

Metal-organic frameworks (MOFs) and Hybrid organic inorganic perovskites (HOIP) are both classes of hybrid materials (materials containing both organic and inorganic components) which have had growing interest in recent years. Historically, work on these types of materials has primarily focussed on their crystalline forms, until recently, where studies have shown that their amorphous and glassy states can also be accessed through a range of methods including, but not limited to, melt-quenching and mechanochemical methods. These discoveries have led to the introduction of a new category of glass materials, hybrid glasses, which lie between the domains of both inorganic and organic glasses. Although these materials are amorphous by definition, studies have shown that short range order can still be retained suggesting that properties possessed by the crystalline forms may be carried over during the structure transformations. This new area of materials chemistry offers possible applications in gas storage and separation, catalysis and optical applications.Although the field of glass chemistry is diverse in itself with a range of applications, a wider and more varied range of materials can be developed by considering composites of glasses with other solid-state materials. Careful choice of the type and quantities of constituent parts which make up these composites introduces a great degree of control and subsequently the ability to tailor underlying chemistries and specific material properties to better suit targeted applications.The aim of this project is to study the synthesis and properties of composite materials based upon hybrid glasses. The nature of composite formation and resulting material properties will be explored by creating a diverse range of composite materials, such as glass ceramic analogues and glass-carbon composites. Diffraction techniques and thermo-analytical methods such as powder x-ray diffraction (PXRD); differential scanning calorimetry (DSC); and thermogravimetric analysis (TGA) will be used to investigate the initial formation of the glasses and their composites. Once formed, the bulk properties of the materials will be probed by use of techniques such as gas sorption and indentation with an aim at identifying potential future applications.
