传统的单功能抗菌材料因为自身的局限性在实际应用中存在许多问题。杀菌-防污功能可转换材料保留了单功能抗菌材料的优点并克服了其缺点，成为抗菌材料新的发展方向。介绍了两性离子聚合物及其衍生物、聚（N-异丙基丙烯酰胺）（PNIPAAm）及其他刺激响应聚合物在杀菌-防污功能可转换抗菌材料领域的应用和抗菌机理，并总结了抗菌材料发展面临的困难，展望了未来的发展方向。

Bacteria distribute everywhere and bring many problems to human health and industrial development.Traditional single-function antibacterial materials are facing many problems due to their limitations in practical application.The materials with convertible functions between bacteria-killing and foul-releasing can remain the advantages of single-function antibacterial materials and overcome their disadvantages,becoming a new development direction for antibacterial materials.This paper introduces the application and antibacterial mechanism of zwitterionic polymers and their derivatives,poly(N-isopropylacrylamide) (PNIPAAm) and other stimulation-responsive polymers in the field of kill-release convertible materials,summarizes the difficulties in the development of antibacterial materials,and forecasts the development direction of antibacterial materials.
