Adhesive Performances of 3D Printed Biomimetic Mussel Byssal Structures
摘要
Abstract
The mussel byssal is a high-performance biological device that provides adhesion between the mus-sels and solid surfaces in different environments.In recent years,researchers paid increasing attention to the quantitative effects of the composition and macro/microstructure of the mussel byssal on its adhesion perform-ance,with insights for the design of biomimetic adhesive devices.Here,the 3D printing technique was com-bined with the detachment test and the finite element method to systematically investigate the effects of shapes and geometric parameters on the detachment modes and adhesive properties of biomimetic mussel byssal struc-tures.The results reveal the detachment mechanism of the mussel byssal and show that,the mussel byssal has an optimal thread direction angle resulting in optimal adhesion.The effects of the thread-plaque junction posi-tion and the plaque bottom shape on adhesion properties were explored.Furthermore,the simulated complete detachment process of the bundle-like mussel byssal array under vertical traction,and the obtained sawtooth force-displacement curve indicates that,the bundle model has a relatively stable ability to resist detachment.These findings help understand the detachment behavior of the mussel byssal in nature and provide a theoretical guidance for the optimization design of biomimetic adhesive devices.关键词
