Ne efa vɔ la, ƒuƒoƒo si ŋu wotrɔ asi le si me nusiwo woate ŋu abla ɖe wo nɔewo ŋu le la dzɔna ɖe PTFE ƒe anyigba dzi. Esi wònye be nusiwo woate ŋu abla ƒe moleculewo ge ɖe PTFE ƒe molecule ƒe akpa si le etame ta la, kadodoa ƒe gbagbã bia be woagblẽ moleculeawo dome, si wɔnɛ be kadodoa ƒe ŋusẽ lolo.

4. Kekeli ƒe Mɔnu

Wotsɔa PTFE dea monomers siwo woate ŋu awɔ polymerizable siwo wɔa dɔ abe styrene, fumaric acid, methacrylates kple bubuawo ene me, emegbe wotsɔa Co-60 klẽna ɖe edzi . Esia ʋãa atikewo ƒe polymerization na monomers la ɖe PTFE ƒe anyigba dzi, si wɔnɛ be graft polymer layer si woate ŋu abla bɔbɔe. Grafting hã nana eƒe goglome nɔa ƒuƒuie, dzia kadodoa ƒe teƒe ɖe edzi eye wònaa kadodoa ƒe ŋusẽ nyona ɖe edzi.
