As an intermediate state between liquid and solid materials, hydrogels display unique properties, opening a wide scope of applications, especially in the biomedical field. Organic hydrogels are composed of an organic network cross-linked via chemical or physical reticulation nodes. In contrast, hybrid hydrogels are defined by the coexistence of organic and inorganic moieties in water. Inorganic polymerization, i.e. the sol-gel process, is one of the main techniques leading to hybrid hydrogels. The chemoselectivity of this method proceeds through hydrolysis and condensation reactions of metal oxide moieties. In addition, the mild reaction conditions make this process very promising for the preparation of water-containing materials and their bio-applications.
作为液体和固体材料之间的中间状态，水凝胶具有独特的性质，从而开拓了广泛的应用范围，尤其是在生物医学领域。有机水凝胶由通过化学或物理网状节点交联的有机网络组成。相比之下，杂化水凝胶是由有机和无机部分在水中共存来定义的。无机聚合，即溶胶 - 凝胶过程，是制备杂化水凝胶的主要技术之一。该方法的化学选择性通过金属氧化物部分的水解和缩合反应进行。此外，温和的反应条件使该过程在制备含水材料及其生物应用方面非常有前景。
