Abstract：
The formation process of biofouling is actually a 4D process with both spatial and temporal dimensions. However, most traditional antifouling coatings, including slippery liquid-infused porous surface (SLIPS), are limited to performing antifouling process in the 2D coating plane. Herein, inspired by the defensive behavior of sea anemones\' wielding toxic tentacles, a \"4D SLIPS\" (FSLIPS) is constructed with biomimetic cilia via a magnetic field self-assembly method for antifouling. The bionic cilia move in 3D space driven by an external magnetic field, thereby preventing the attachment of microorganisms. The FSLIPS releases the gaseous antifoulant (nitric oxide) at 1D time in response to light, thereby achieving a controllable biocide effect on microorganisms. The FSLIPS regulates the movement of cilia via the external magnetic field, and controls the release of NO overtime via the light response, so as to adjust the antifouling modes on demand during the day or night. The light/magnetic response mechanism endow the FSLIPS with the ability to adjust the antifouling effect in the 4D dimension of 1D time and 3D space, effectively realizing the intelligence, multi-dimensionality and precision of the antifouling process.
摘要：
生物污染的形成过程实际上是一个具有空间和时间维度的4D过程。然而,大多数传统的防污涂料，包括光滑的液体注入多孔表面(SLIPS)，仅限于在2D涂层平面中执行防污工艺。在这里，受到海葵挥舞着有毒触手的防御行为的启发，“4DSLIPS”（FSLIPS）是通过磁场自组装方法用仿生纤毛构建的，用于防污。仿生纤毛在外部磁场的驱动下在3D空间中移动，从而防止微生物的附着。FSLIPS响应光在1D时间释放气体防污剂（一氧化氮），从而实现对微生物的可控杀生物剂效果。FSLIPS通过外部磁场调节纤毛的运动，并通过光响应控制NO超时的释放，以便在白天或晚上根据需要调整防污模式。光/磁响应机制赋予FSLIPS在一维时间和三维空间的4D维中调节防污效果的能力，有效地实现智能，防污工艺的多维性和精确性。
