Kedu ihe dị iche n'etiti PTFE na PVDF

PTFE na-eguzogide ọgwụ na-emebi emebi karịa PVDF ma ọ bụ PE.Ka atọm Fluorine na-adị n'ọkpụkpụ azụ, ka ndị na-edozi ahụ agaghị enwe ike ịbanye na kemịkal n'elu.

A na-eji PTFE na PVDF (durapore) mee ihe na akpụkpọ anụ na-ejikọta protein (Millipore kpọmkwem).N'ikwu okwu kemịkalụ, polymers abụọ ahụ dị iche nke ukwuu n'ihi mmụba nke fluorides na ịdị arọ molekụla.Njirimara ha na-ejikọta protein dịkwa iche.

N'ozuzu, PTFE bụ 'abụghị osisi' karịa PVDF, nke na-abụghị osisi karịa polyethylene (PE).PTFE na-eguzogide ọgwụ na-emebi emebi karịa PVDF ma ọ bụ PE.Ị ziri ezi ileba anya na nhazi kemịkalụ.Ka atọm Fluorine na-adị n'ọkpụkpụ azụ, ka ndị na-edozi ahụ agaghị enwe ike ịbanye na kemịkal n'elu.Ịtụ ihe dị ka akụkụ kọntaktị ga-akwado nke a.Amaghị m otú usoro pore nke membranes si emetụta ihe, mana site na echiche kemịkal, enwere ọdịiche doro anya.

PTFE -poly tetra fluoro ethylene na PVDF -polyvinylidene fluoride abụọ bụ polymers eji maka hydrophobic onwunwe nke electrode iji zere idei mmiri nke cathode ihe (carbon ákwà) .Ọtụtụ n'ime ọmụmụ, ha na-eji PTFE ngwọta karịa ndị ọzọ ụdị ihe ngwọta ...

Ha abụọ kwụsiri ike nke ọma.Chee na ihe kpatara ya bụ na ikpeazụ electrode morphology, n'ihi na PVDF ihe nkedo eji dị ka ezi ngwọta (glue), mgbe PTFE otu bụ a nkwusioru na unsoluble nanosized ahụ.

PVDF na-emeghachi omume karịa PTFE n'okpuru ọnọdụ ụfọdụ.
