Gecko-inspired adhesives

In a design approach unique among gecko-inspired adhesives, hiodegradable dextran-coated poly(glycerol-co-sebacate acrylate) has been used to create patterned arrays of microscale truncated cones, and used to improve attachment of adhesive tapes to tissue surfaces. While this biocompatible, elastomeric material is not intended for reversible adhesion and...

Other prerequisites for the successful development of useful products lie in so far unexplored properties How do gecko surfaces behave under repeated contact formation and breakage How do they respond to changes in temperature and humidity What is their long-term reliability in specific environments And, most important, can they ever be fabricated cost-effectively over large areas Only if these and similar problems can be successfully overcome, will gecko-inspired adhesives realize their potential in applications. 

Use of nanotubes have been reported by Ge et al. (2007) in enhancing adhesion by gecko-inspired adhesion in production of carbon nanotube-based synthetic gecko tapes, and by Sethi et al. (2008) in the production of gecko-inspired carbon nanotube-based self-cleaning adhesives. More information about nanocomposite adhesives can be found in O Chap. 55.

The book b ins with a chapter that describes certain functions of the skin which contributes to the new area of bio-inspired design. The next four chapter have more specific subjects with its technological applications. Chapter 2 analyzes the shark skin effect or the commonly known antifriction surfaces. Chapter 3 discusses the Lotus effect or the usually known self-cleaning surfaces. Chapter 4 analyzes the Moth-eye effect or the commonly known antireflection surfaces and Chap. 5 describes the Gecko effect or the usually known dry adhesive surfaces.
