Nafion is a sulfonated tetrafluoroethylene based fluoropolymer-copolymer discovered in the late 1960s by Walther Grot of DuPont. It is the first of a class of synthetic polymers with ionic properties which are called ionomers.his form of Nafion, referred to as the neutral or salt form, is finally converted to the acid form containing the sulfonic acid (-SO 3 H) groups. Nafion can be cast into thin films by heating in aqueous alcohol at 250 Â°C in an autoclave.

The two ways that organisms on the bottom of deep sea food chains acquire energy is by chemosynthesis and marine snow. Chemosynthesis is the biological conversion of one or more carbon-containing molecules and nutrients into organic matter. Marine snow is a shower of organic material falling from upper waters to the deep ocean.
