摘　　要：Attachment of bacteria and subsequent formation of biofilms on material surfaces lead to serious consequences including infection,contamination and biofouling,posing a prominent threat to human health and causing problems in many industries.Therefore,it is highly desirable to endow the surfaces with antibacterial properties.Traditional antibacterial surfaces are designed via either bacteria-resisting strategy to prevent the initial adhesion of bacteria or bacteria-killing strategy to eradicate any bacteria that attach to the surface.However,these single-function surfaces have their inherent shortcomings and cannot realize long-term efficacy against bacteria.In recent years,various dual-function antibacterial surfaces with both bacteria-resisting and bacteria-killing properties together have been developed,showing better performance for combating surface-attached bacteria and preventing formation of biofilms.In this review,we summarize the recent development of these dual-function antibacterial surfaces.We focus on the design principles and fabrication strategies of such surfaces and highlight the representative examples,which are categorized specifically into two types according to the anti-adhesive and bactericidal properties are simultaneous or switchable.A brief perspective is finally presented on current challenges and future research directions.
