“What happens when polymer chains link together?”
Polymers are famous for their absolutely long chains. However what happens when these chains link together? Well, let’s use our scientific mindsets to find out. If we look carefully, then we will observe that the density of the materials will go down (since now all of its composing elements will no longer be able to be squeezed together so easily) but the strength will increase since the there are now three-dimensional impediments to dislocations.
