WebIntroduction to Polymers. Molecules are compounds that are made of more than one type of atom. An example of a small molecule is water--it contains three atoms--two of hydrogen and one of oxygen. Polymers are very large molecules compared to water. They have many more atoms than a water molecule--from 10,000 to 100,000 atoms per molecule. crypto law cleWebApr 14, 2024 · The increased interest in the transition from liquid to solid polymer electrolytes (SPEs) has driven enormous research in the area polymer electrolyte technology.
