The present invention relates to substrates comprising a crosslinked network of covalently attached antimicrobial and/or antibiofouling polymers. The crosslinked network of antimicrobial and/or antibiofouling polymers acts highly efficiently against pathogens, e.g. bacteria and fungi. Both the antimicrobial and the antibiofouling cross-linked polymer networks are preferably better resistant to mechanical damage than simple surface-immobilized polymer monolayers. The antimicrobial and/or antibiofouling polymers of the crosslinked network are preferably obtained by ring opening metathesis polymerization (ROMP) and exhibit a molecular weight of more than 1,000 g mol-1, preferably of more than 10,000 or even 100,000 g mol-1. The crosslinked network of antimicrobial and/or antibiofouling polymers is preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc. The present invention is also directed to uses of crosslinked networks of antimicrobial and/or antibiofouling polymers as defined herein, e.g. for coating a surface of a substrate, and to methods therefore.
本发明涉及由共价连接的抗菌和/或防污聚合物交联网络组成的基材。交联的抗菌和/或防污聚合物网络可高效对抗细菌和真菌等病原体。与简单的表面固定聚合物单层相比,抗菌和抗生物污染交联聚合物网络具有更好的抗机械损伤能力。交联网络中的抗菌和/或防污聚合物最好是通过开环偏析聚合(ROMP)获得,分子量大于 1,000 g mol-1,最好大于 10,000 或甚至 100,000 g mol-1。抗微生物和/或抗生物污染聚合物的交联网络最好共价连接到基质表面,例如植入物、医疗器械、医疗设备或(组织支撑)生物材料等。本发明还涉及本文定义的抗微生物和/或抗生物污垢聚合物交联网络的用途,例如用于基底表面涂层,以及相关方法。
