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）和混合有机无机钙钛矿（HOIP）都是近年来越来越兴趣的混合材料（含有有机和无机成分的材料）。从历史上看，这些类型的材料的工作主要集中在其晶体形式上，直到最近，研究表明，他们的无定形和玻璃状态也可以通过一系列方法访问，包括但不限于熔融液压和机械化学方法。这些发现导致引入了一种新的玻璃材料，混合玻璃，这些玻璃杯位于无机玻璃和有机玻璃的域之间。尽管这些材料从定义上是无定形的，但研究表明，仍然可以保留短距离顺序，这表明在结构转化过程中，晶体形式所具有的特性可以延续。这种新的材料化学领域化学领域在气体存储和分离，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是多种多样的，但可以通过考虑与其他固态材料的玻璃材料来开发更广泛和更多种材料。仔细选择组成这些复合材料的组成部分的类型和数量引入了很大程度的控制，随后可以量身定制基础化学和特定材料特性以更好地适合有针对性的应用。该项目的目的是研究基于混合玻璃的合成和特性。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，将探索复合形成和所得材料特性的性质。衍射技术和热分析方法，例如粉末X射线衍射（PXRD）；差异扫描量热法（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，将通过使用诸如加油和压痕等技术来探测材料的批量特性，以识别潜在的未来应用。
