PTFE da PVDF (durapore) ana amfani da su duka a cikin membranes masu haɗa furotin (Millipore musamman).Maganar sinadarai biyun polymers sun bambanta sosai saboda ƙarin fluorides da nauyin kwayoyin halitta.Abubuwan da ke daure furotin su ma sun bambanta.
Gabaɗaya, PTFE ya fi PVDF 'mara ƙarfi', wanda ba shi da sanda fiye da polyethylene (PE).PTFE ya fi juriya ga lalata fiye da PVDF ko PE.Kuna daidai don duba tsarin sinadarai.Yawan zarra na Fluorine akan kashin baya, yawan sunadaran ba za su iya liƙawa sama da sinadarai ba.Auna abubuwa kamar kusurwar lamba zai tabbatar da hakan.Ban san nawa tsarin kumbura na membranes ke shafar abubuwa ba, amma daga mahangar sinadarai, akwai bambance-bambance a sarari.
PTFE -poly tetra fluoro ethylene da PVDF -polyvinylidene fluoride duka su ne polymers da aka yi amfani da su don dukiyar hydrophobic na lantarki don kauce wa ambaliya na kayan cathode (carbon zane) .Mafi yawa a cikin binciken, suna amfani da maganin PTFE fiye da sauran nau'in bayani ...
