We report the preparation of tough double-network (DN) metallopolymer antibacterial hydrogels through dual polymerization. DN hydrogels are composed of the first network of cationic cobaltocenium polyelectrolytes enabled using ring-opening metathesis polymerization and the second network of polymers prepared using radical polymerization. These DN hydrogels exhibited a very high compressive stress (up to ∼120 MPa). The introduction of boronic acid and ionic conjugation with β-lactam antibiotics endowed the hydrogels with high antimicrobial efficacy against both Gram-positive and Gram-negative bacteria.

双重聚合的坚韧抗菌金属聚合物双网络水凝胶

我们报道了通过双重聚合制备坚韧的双网络 ( DN ) 金属聚合物抗菌水凝胶。DN水凝胶由使用开环复分解聚合实现的阳离子钴聚电解质的第一个网络和使用自由基聚合制备的聚合物的第二个网络组成。这些DN水凝胶表现出非常高的压缩应力（高达~120 MPa）。硼酸的引入和与β-内酰胺抗生素的离子缀合赋予水凝胶对革兰氏阳性和革兰氏阴性细菌的高抗菌功效。
