有效地消除水中广泛的微生物污染对于解决严重的环境问题具有重要意义。在此，我们展示了一种新的策略，通过共价引入乙内酰脲基团到CMP网络（命名为CMPH）的新型CMP为基础的抗菌剂。所得到的CMPH显示出优异的物理化学稳定性、大的比表面积（高达1411 m2 g−1）和高的抗菌活性（在100 μg mL−1分散体浓度下在120 min内完全抑制细菌生长）。据我们所知，这是基于CMP的抗菌剂的第一个例子。此外，CMPH不仅可以制成整体纳米多孔泡沫，而且可以负载在各种多孔基底上，以制备具有成本效益的杀菌材料，显示出其在水清洁方面的实际应用的巨大潜力。更重要的是，本研究的结果可能打开一个通用的路线，设计和制造的抗菌材料的CMP的基础上，通过简单的一锅反应，方便地引入不同的抗菌取代基到CMP积木。
Efficient elimination of widespread microbial contamination in water is of great importance to address severe environmental issues. Herein, we demonstrate a new strategy for fabricating novel CMPs-based antibacterial agents by covalently introducing hydantoin groups into CMPs networks (named as CMPH). The resulting CMPH show excellent physicochemical stability, large specific surface areas (up to 1411 m2 g−1) and high antibacterial activity (completely inhibiting growth of bacteria at 100 μg mL−1 dispersion concentration in 120 min). To our knowledge, this is the first example of a CMPs-based antibacterial agent. Furthermore, the CMPH can not only be fabricated as monolithic nanoporous foam, but also can be loaded on diverse porous substrates to fabricate cost-effective sterilization materials, showing great potentials for their practical applications in water cleanness. More importantly, the findings of this study may open a versatile route for design and fabrication of CMPs-based antibacterial materials by the facile introduction of diverse of antibacterial substituents into CMPs building blocks followed by a simple one-pot reaction.
