摘要

Most materials get thinner when stretched, but auxetics do the opposite and get thicker. Helen Gleeson at the University of Leeds, UK, describes her group's discovery of a material that is auxetic at the molecular level, which could be used in everything from body armor to laminated glass.What's so interesting about this liquid crystal elastomer's (LCE's) auxetic behavior is that it occurs at the molecular scale rather than relying on the behavior of macroscopic pores found in other "first-generation" synthetic auxetic materials. It therefore does not become inherently weaker when stretched, which means it could be used, say, as body armor, where you need a material that is likely to come under a lot of impact. The material would then act as a shock absorber-thickening in response to the force, rather than becoming thinner like a standard positive-Poisson-ratio material. From Physics World.
