Skin sebaceous glands inspired sustainable and robust slippery lubricant infused porous surfaces

Slippery lubricant infused porous surfaces (SLIPS) have been extensively implemented in the fields of marine biofouling prevention, anti-icing, and corrosion protection. However, the limitations in lubricant loss restrict its effective applications. Inspired by sebum storage and secretion in skin sebaceous glands, we developed a robust SLIPS by integrating porous Ganoderma lucidum spores (GLS) as natural oil-reservoir into a self-healing polyurethane matrix. The GLS particles has abundant surface pores and vast internal cavities, which can enable efficient locking and sustained replenishment of infused lubricant. The GLS-based SLIPS(GLS-SS) exhibits outstanding liquid repellency, extremely low friction, and remarkable long-term anti-scaling performance. It also significantly delays ice nucleation (588 s), achieves ultralow ice adhesion (∼0.2 kPa), and enables efficient photothermal de-icing. Crucially, GLS-SS effectively inhibits protein adsorption, bacterial adhesion, biofilm formation, and microalgal colonization. A 100-day marine field test demonstrates negligible biofouling, and high-throughput 16S rRNA sequencing reveals a dramatic reduction in microbial diversity and suppression of dominant fouling taxa. Additionally, the GLS-SS coating exhibits excellent resistance to microbiologically influenced corrosion and retains underwater self-healing capability. This work offers a durable and sustainable solution for long-term material protection in complex marine environments.
