Rational design and nanofabrication of gecko-inspired fibrillar adhesives.
Gecko feet integrate many intriguing functions such as strong adhesion, easy detachment, and self-cleaning. Mimicking gecko toe pad structure leads to the development of new types of fibrillar adhesives useful for various applications. In this Concept article, in addition to the design of adhesive mimics by replicating gecko geometric features, we show a new trend of rational design by adding o...
متن کاملWet self-cleaning of biologically inspired elastomer mushroom shaped microfibrillar adhesives.
We report that hydrophilic polyurethane mushroom shaped microfiber arrays possess wet self-cleaning ability using the lotus effect as biologically inspired synthetic fibrillar adhesives. In comparison with a flat surface made of the same polyurethane, the fiber array exhibited almost 100% wet self-cleaning without any degradation of adhesive strength. We attribute this cleaning ability to the m...
متن کاملFlexible carbon-nanofiber connectors with anisotropic adhesion properties.
The ability of gecko lizards and many insects to climb vertical surfaces relies on the hierarchical microand nanofibrillar arrayed features on their feet. The fibrillar structures provide conformal contact with the opposing surfaces to maximize the van der Waals (vdW) interactions. These adhesive systems found in nature have inspired researchers to design synthetic adhesives by using fibrillar ...
متن کاملPhylogenetic analysis of the scaling of wet and dry biological fibrillar adhesives.
Fibrillar, or "hairy," adhesives have evolved multiple times independently within arthropods and reptiles. These adhesives exhibit highly desirable properties for dynamic attachment, including orientation dependence, wear resistance, and self-cleaning. Our understanding of how these properties are related to their fibrillar structure is limited, although theoretical models from the literature h...

This work reports thin-film terminated micro-fibrillar adhesives made of adhesive polymers and shape memory polymers as reversible dry adhesives with thermally controllable adhesion. Structurally different adhesives were fabricated by coating a continuous thin layer of an elastomeric adhesive polymer onto either a flat or a fibrillar shape memory polymer surface. Experimental results exhibited ...
