CO₂ mitigation by cycloaddition to bis-epoxides to obtain bis-cyclocarbonates (CC) paved one way to a new class of polyurethanes (PUs), the non-isocyanate polyurethanes (NIPUs). By using molecules functionalized with alkoxysilyl groups as end chain it is possible to obtain hybrid NIPUs, also called urethanesils, by sol–gel chemistry. Using bis-cyclocarbonate polydimethylsiloxane (CCPDMS) with proper diamines and end-chain amino silanes followed by sol–gel processing leads to versatile hybrid non-isocyanate polydimethylsiloxane urethanes (PDMS-urethanesil). This review reports—besides our recent studies about PDMS-urethanesil materials—the sol–gel chemistry applied to synthesize urethanesil and its applications. While the antimicrobial, photochromic, and anticorrosion properties of urethanesil loaded with phosphotungstic acid as well as the luminescent effect of material loaded with Eu³⁺ have already been reported, antimicrobial features of urethanesil loaded with phosphoric acid are our newest findings which we herein report for the first time. The impact of the inorganic acid used on the sol–gel process is highlighted together with the importance of antibiofouling properties. Although the antibiofouling mechanism is still under investigation, the broad spectrum of action of phosphoric acid-loaded urethanesil is worth mentioning, since it has been tested to be efficient against some pathogenic bacteria including a drug resistant Staphylococcus aureus strain as well as pathogenic fungi and yeast. Due to the simple, straightforward, and highly reproducible synthesis as well as the opportunity to obtain versatile materials with tuneable mechanical and physical properties, this new class of hybrid materials promises to be applicable in different industrial fields.

一氧化碳₂通过环加成双环氧化物获得双环碳酸酯（CC）的缓解方法为新型聚氨酯（PU）非异氰酸酯聚氨酯（NIPU）铺平了道路。通过使用被烷氧基甲硅烷基团官能化的分子作为末端链，可以通过溶胶-凝胶化学方法获得杂化NIPU，也称为氨基甲酸酯。将双环碳酸酯聚二甲基硅氧烷（CCPDMS）与适当的二胺和端链氨基硅烷一起使用，然后进行溶胶-凝胶加工，可得到通用的杂化非异氰酸酯聚二甲基硅氧烷聚氨酯（PDMS-urethanesil）。这篇综述报告，除了我们最近对PDMS-氨基甲酸酯材料的研究之外，溶胶-凝胶化学技术还用于合成氨基甲酸酯硅及其应用。而抗菌剂，光致变色剂，已经报道了³⁺，载有磷酸的氨基甲酸酯的抗菌特性是我们的最新发现，这是我们在此首次报道。强调了无机酸对溶胶-凝胶工艺的影响以及抗污垢特性的重要性。尽管抗污垢机理仍在研究中，但值得一提的是负载磷酸的氨基甲酸酯硅具有广谱的作用，因为已对它进行了有效的抗某些病原菌的测试，包括耐药的金黄色葡萄球菌。菌株以及致病性真菌和酵母菌。由于简单，直接和高度可重复的合成，以及获得具有可调节机械和物理特性的通用材料的机会，这种新型的混合材料有望应用于不同的工业领域。
