The inclined bionic hair can effectively enhance the adhesion and friction of the surface of the object, providing a reference point for the design of adhesive materials and the development of robots. In this paper, we introduce a new design of inclined bionic hair, which is prepared by combining the microporous manufacturing process with PDMS base material, and utilize ultraviolet silicon dioxide gel to solidify to achieve the inclination of the hair. We studied the adhesion performance of this design at different inclination angles and compared it with the adhesion performance of traditional bionic hair. The results show that the inclined bionic hair has better adhesion performance, and the adhesion performance improves as the angle increases.Methods:The inclined bionic hair is prepared by combining the microporous manufacturing process with PDMS base material. Firstly, the microstructure of the hair is designed, and then the PDMS base material is poured onto the mold, and the mold is left to cure for 24 hours. After curing, the PDMS base material is peeled off from the mold, and the ultra-violet silicon dioxide gel is dripped onto the inclined surface of the hair for curing. After curing, the inclined bionic hair is formed.Results:We studied the adhesion performance of inclined bionic hair at different inclination angles. The results show that with the increase of inclination angle, the adhesion performance of the hair increases. When the inclination angle is 30 degrees, the adhesive force of the hair is 2.5 times that of the traditional bionic hair, and the friction force is 1.8 times that of the traditional bionic hair. When the inclination angle is 60 degrees, the adhesive force of the hair is 3.8 times that of the traditional bionic hair, and the friction force is 2.5 times that of the traditional bionic hair. This demonstrates the superior adhesive properties of the inclined bionic hair.Conclusions:In summary, we have successfully prepared inclined bionic hair by combining the microporous manufacturing process and PDMS base material, which is suitable for producing inclined bionic hair with different inclination angles. The inclined bionic hair has superior adhesion properties compared to traditional bionic hair, and the adhesion properties increase as the inclination angle increases. This research provides a new method and reference point for the preparation and design of inclined bionic hair, creating new possibilities for adhesion and friction in the field of robotics. Further research is still required to optimize the preparation process and explore the potential applications of inclined bionic hair.Keywords: bionics, inclined bionic hair, microporous manufacturing, ultra-violet silicon dioxide gel, adhesion performance.Discussion:The research on inclined bionic hair is expected to bring new breakthroughs in the fields of robotics, adhesion and friction, and material science. In recent years, many researchers have focused on the design and preparation of bionic hair, especially inclined bionic hair, because of its superior adhesion and friction properties.The design and preparation of inclined bionic hair is mainly based on the bionics principle of gecko feet, which have excellent adhesion properties. The gecko feet consist of millions of hair-like structures called setae, each of which has thousands of branches called spatulae. The spatulae maximize the interaction between the setae and the surfaces they contact, creating strong and reversible adhesion. Inspired by this principle, researchers have designed and prepared artificial inclined bionic hair with similar structures to enhance adhesion and friction.Inclined bionic hair has many potential applications in the field of robotics. For example, it can be used to design robots with the ability to climb vertical walls and walk on ceilings, which could be useful for tasks such as inspection and maintenance of high-rise buildings or exploring hard-to-reach places. Inclined bionic hair could also be used to enhance the adhesion and friction of various surfaces in microelectronic devices, medical equipment, and other fields, where the performance of the materials is critical.In the current study, we prepared inclined bionic hair by combining the microporous manufacturing process with PDMS base material and ultraviolet silicon dioxide gel. The microporous manufacturing process is a common method for fabricating microscale structures with precise shape and size, while PDMS base materia
