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.
Antarctic Ecosystem: Abundance of Life Diatoms like these are at the base of the Antarctic food chain. In summer they use photosynthesis to grow, and multiply into huge populations. Young (juvenile) krill that were collected in a net. A curious Emperor penguin approaches a technician.
   Plant life on and around Antarctica is restricted to bryophytes  (mosses and liverworts),200 species of lichen, over 600 species of  algae (most of which are phytoplankton), seaweed, pearl-wort and  hair grass.    There are also no human populations native to the Antarctic  continent.here is nothing that lives permanently on the Antarctic continent  itself by way of animal life. There are no land animals that are  mammals, nor any reptiles or amphibians â¦ native to Antarctica. The  continent is too cold to support animal life.
