WebMay 10, 2016 · For the first time, researchers have created a type of stretchy, polymer film that they're claiming acts like a 'second skin' barrier layer. That's a big deal, because it means it could one day be used to protect us from sunburn and treat conditions like eczema, but what people are getting really excited about is the fact that it also seems to work like a … WebA polymer is an organic material and the backbone of every organic material is a chain of carbon atoms. The carbon atom has four electrons in the outer shell. Each of these valence electrons can form a covalent bond to another carbon atom or to a foreign atom. The key to the polymer structure is that two carbon atoms can have up to three common ...

Creating a polymer that is strong, durable and resistant to stress and strain is no easy feat. Single molecules are combined in a very specific way—like a house of cards—to create large macromolecules. Without an instrument to help identify strain or stress, a polymer might seem to be without flaw until it fails.
