Question: Which is the first Synthetic material that gets thicker on stretching?
(a) Liquid Crystal Elastomer
(b) Benzaldehyde
(c) Formalin
(d) Thermoplastics
Answer: (a)
Related facts:
- According to Dr. Devesh Mistry from Leeds’ School of Physics and Astronomy told Digital Trends about a new synthetic material Liquid Crystal Elastomer which actually gets thicker the more it’s stretched.
- Governing branch of science which deals with its study is known as Auxetics. Auxetic materials get thicker and they are also great at energy absorption and resisting fracture.
- Some examples of other Auxetic materials include cat skin, tendons in the human body, and the protective layer in muscle shells.
- In some cases experiments on these materials prove them to be weak & porous.
- There may be many potential applications for materials with these properties including body armour, architecture and medical equipment.
