Abstract
Molecular hybrid materials based on widely available polymers crosslinked with an inorganic species have received increasing interest for their unique property sets outside of the usual range of commodity plastics and/or nanocomposites. Here, we provide a mini-review on molecular hybrids based on metal oxide hydrates—compounds that readily react with, for example, hydroxylated polymers to form inorganic:organic materials systems with many desirable features and properties. Focusing on titanium oxide hydrates, we discuss here that such molecular hybrids can exhibit a broad refractive index range in addition to an increased glass transition temperature, mechanical stiffness and swelling resistance in comparison to the neat polymer, which illustrates that such hybrid systems offer a new, low-cost, robust and versatile functional materials platform with great promise for, for example, solution-processed photonics, catalysts and antimicrobial coatings. Generally, our mini-review seeks to provide a concise and accessible overview of titanium oxide hydrate:polymer hybrid systems, focusing on their unique properties and processability as well as their broad and largely untapped potential as functional materials. © 2024 The Author(s).

作为多功能聚合物交联剂和分子杂化形成剂的氧化钛水合物
基于与无机物交联的广泛可用聚合物的分子杂化材料,因其超出普通商品塑料和/或纳米复合材料范围的独特性能而受到越来越多的关注。在此,我们将对基于金属氧化物水合物的分子杂化材料进行小型综述--这种化合物很容易与羟基聚合物等发生反应,形成具有许多理想特性和性能的无机:有机材料系统。以氧化钛水合物为重点,我们在此讨论,与纯聚合物相比,这种分子杂化物除了能提高玻璃化转变温度、机械刚度和抗溶胀性之外,还能显示出宽广的折射率范围,这说明这种杂化物体系提供了一种新型、低成本、坚固耐用且用途广泛的功能材料平台,在溶液加工光子学、催化剂和抗菌涂层等方面大有可为。总体而言,我们的微型综述旨在提供有关氧化钛水合物:聚合物杂化体系的简明易懂的概述,重点关注其独特的性能和可加工性,以及作为功能材料尚未开发的广泛潜力。© 2024 作者简介国际聚合物》由 John Wiley & Sons Ltd 代表化学工业协会出版。
