Gecko-InspIred polymer AdhesIves
The discovery of the gecko’s remarkable foot adhesion has provided a riddle for engineers and scientists to solve: how can an adhesive surface be selectively sticky, directional, remain clean, and work on almost any material? Gecko feet stick to almost anything, in almost any condition (including underwater and in space), but do not stick unintentionally, do not stick to dirt, and enable the ge...
متن کاملGecko-inspired bidirectional double-sided adhesives.
A new concept of gecko-inspired double-sided adhesives (DSAs) is presented. The DSAs, constructed by dual-angled (i.e. angled base and angled tip) micro-pillars on both sides of the backplane substrate, are fabricated by combinations of angled etching, mould replication, tip modification, and curing bonding. Two types of DSA, symmetric and antisymmetric (i.e. pillars are patterned symmetrically...
متن کاملEnhanced adhesion by gecko-inspired hierarchical fibrillar adhesives.
The complex structures that allow geckos to repeatably adhere to surfaces consist of multilevel branching fibers with specialized tips. We present a novel technique for fabricating similar multilevel structures from polymer materials and demonstrate the fabrication of arrays of two- and three-level structures, wherein each level terminates in flat mushroom-type tips. Adhesion experiments are co...
متن کاملHuman climbing with efficiently scaled gecko-inspired dry adhesives.
Since the discovery of the mechanism of adhesion in geckos, many synthetic dry adhesives have been developed with desirable gecko-like properties such as reusability, directionality, self-cleaning ability, rough surface adhesion and high adhesive stress. However, fully exploiting these adhesives in practical applications at different length scales requires efficient scaling (i.e. with little lo...
متن کاملRational 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...
