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.

金属有机框架（MOF）和杂化有机无机钙钛矿（HOIP）都是近年来引起人们越来越多兴趣的杂化材料（同时含有有机和无机成分的材料）。从历史上看，对这些类型材料的研究主要集中在它们的晶态上，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。这些发现催生了一种新型玻璃材料——混合玻璃，它介于无机玻璃和有机玻璃领域之间。尽管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，这表明晶体形式所拥有的特性可以在结构转变过程中保留下来。这一新的材料化学领域为气体储存和分离、催化和光学应用提供了可能的应用。尽管玻璃化学领域本身具有广泛的应用范围，但通过考虑复合材料可以开发更广泛、更多样的材料。玻璃与其他固态材料。仔细选择构成这些复合材料的组成部分的类型和数量，可以实现很大程度的控制，从而能够定制基础化学物质和特定材料特性，以更好地适应目标应用。该项目的目的是研究合成和基于混合玻璃的复合材料的性能。将通过创建各种复合材料（例如玻璃陶瓷类似物和玻璃-碳复合材料）来探索复合材料形成的本质和由此产生的材料特性。衍射技术和热分析方法，例如粉末 X 射线衍射 (PXRD)；差示扫描量热法（DSC）；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，以确定潜在的未来应用。
