WebPolimero. Singole catene polimeriche visualizzate al microscopio a forza atomica. Un polimero (dal greco polymerḗs, comp. di polýs- e -méros, letteralmente "che ha molte parti" [1]) è una macromolecola, ovvero una molecola dall'elevato peso molecolare, costituita da un gran numero di gruppi molecolari (o unità strutturali) uguali o ... WebPolymers are long chains of atoms bonded to each other. In most plastics, the long chain is a chain of carbon atoms with other atoms attached to them. The different atoms and the shape and length of the chains change how the plastic looks and works. People experimented with plastics based on natural polymers for a very long time.
