Biomimetic nano/microfabrication techniques in multi‐bioinspired superhydrophobic wood: New insight on theory, design and applications

The biomimetic construction of the nature-inspired superwettability systems has been extensively utilized in wood technology, but their design, preparation, and practical application still face significant challenges. Based on the principles of biomimetics, this review outlines the basic theories of design superhydrophobic surface, including Young's equation, Wenzel's equation, Cassie-Baxter's equation and contact angle hysteresis. Meanwhile, recent research advances in bioinspired superwettability wood, which mimic natural biological structures with specific functions by combining advanced preparation techniques such as physical modeling, interfacial chemistry, and physicochemical approaches, are then reviewed. Subsequently, this paper summarizes the widened scope of applications for nanoparticles in superhydrophobic systems and their impact on the study of functional enhancements in wood, including wear resistance, buoyancy, magnetism, liquid corrosion resistance and thermal stability, is summarized. From a nature-inspired perspective, an understanding of superwettability in nature serves as the principles for developing a broad spectrum biomimetic functional superhydrophobic wood and durable fluorine-free environmentally friendly solvents.
