Lesi sihloko sihlola ukuthi kungenzeka yini ukwelashwa kwelangabi lokuguqulwa kwendawo ye-PTFE futhi iqhathanise imiphumela ne-corona kanye nokwelashwa kwe-plasma. Ukuba nokwenzeka: ilangabi lingashintsha i-PTFE kodwa akuvamile ukuthi lisetshenziswe ezimbonini — izingozi zokuphepha (i-PTFE ibola ikhipha i-HF enobuthi ne-perfluoroisobutylene); ukusebenza kunomkhawulo (amandla angaphezulu angama-30-35 mN/m kuphela, enza isendlalelo somngcele esibuthakathaka). Izindlela zokusebenza: ilangabi — i-oxidation yesikhashana ephezulu yezinga lokushisa (>1000°C), i-etching kancane, amaqembu ambalwa omoya-mpilo; i-corona - ukukhishwa kwe-voltage ephezulu kukhiqiza i-ozone/i-oxygen esebenzayo, i-oxidation emnene, ukuminyana kwamandla aphansi akukwazi ukuphula izibopho ze-CF; i-plasma — izinhlayiya ezinamandla/ama-electron/ama-radicals wamahhala ahlukanisa ngokuqondile izibopho ze-CF namaqembu e-polar axhunyelelwe (i-hydroxyl, i-carboxyl, i-amino).
