PTFE Molecules Structure n’a ka jogo ɲumanw

I n’a fɔ PTFE finiw dilannikɛla ŋana, Jiangsu Aokai New Materials bɛ na ni baarakɛlaw ka hakilinaw ye aw bolo. PTFE fini min bɛ funteni caman na, o yɔrɔ koloma ye Politetrafluoroethylene (PTFE) ye, min ka molekiyɔmu jɔcogo ye (mathbf{-(CF_2-CF_2)_n-}) ye. Kabɔn cakɛda kunba bɛ siri pewu ni fluorine atomu ye. Nin jogo saba sanfɛtaw bɛ bɛn PTFE mɔlikuluw jɔcogo ma hakɛw la minnu tɛ kelen ye:

1. Nafolo ɲumanba min tɛ sɔgɔ

A bɛ bɔ sanfɛla fanga dɔgɔyalenba la, min bɛ latigɛ ni fluorine atomu kɛnɛma sirili sirilen ye  ani molekiyɔmu non-polarite.

·  Fluorine atomuw ka lakanani nɔba : Fluorine de ka electronégativité barikama ka bon ani a ka van der Waals radius ka bon. Fluorine atomu minnu bɛ labɛn tuma bɛɛ ani ka caya ka kɛ jiribolo ye kabon cakɛda kɛnɛma fan fɛ, olu bɛ kɛ lakanani bɔgɔlan sirilen ye ani ka yɔrɔ nɔgɔlen dɔ dilan min falen don fluorin dafalen na.

·  Fanga barikama min bɛ molekiyɔmuw ni ɲɔgɔn cɛ : Hali ni CF jɛɲɔgɔnya ye polari barikama ye, a labɛncogo min bɛ bɛn ɲɔgɔn ma kosɛbɛ, o bɛ molekiyɔmu cakɛda bɛɛ kɛ polari tɛ. Yaala-fanga barikamaw dɔrɔn de bɛ sɔrɔ mɔlikuluw ni ɲɔgɔn cɛ, o bɛ na ni sanfɛla fanga dɔgɔyali ye kosɛbɛ (18 mN/m ɲɔgɔn). A bɛ se ka fɔ ko fɛn si tɛ se ka jɛnsɛn walima ka nɔrɔ PTFE sanfɛla la.

2. Asidi & Alkali sɔgɔli barikama

A bɛ bɔ kemikɛli jɛɲɔgɔnya inertness (kemisɛri jɛɲɔgɔnya inertness) la min ka bon kosɛbɛ, min bɛ dantigɛ ni CF jɛɲɔgɔnya fanga caman ye  ani steric shielding effect.

·  CF jɛɲɔgɔnya fanga ka bon : CF jɛɲɔgɔnya bɛ ni jɛɲɔgɔnya fanga ye min ka bon kosɛbɛ (485 kJ/mol ɲɔgɔn), a sabatilen don kosɛbɛ ka tɛmɛ CH ni CC jɛɲɔgɔnyaw kan, wa a tiɲɛni ka gɛlɛn kosɛbɛ.

·  Lakanali dafalen : Fluori atomi bɔgɔlan min ka bon, o bɛ karɔbɔli cakɛda kolotugudaw datugu ka ɲɛ, o bɛ ion sɔgɔlenw bali ka maga karɔbɔli cakɛda la min bɛ se ka kɛ kemikɛli ye. A bɛ farikolo ni kemikaliya lakanani inert fila sɔrɔ.

3. Kuranko ɲɛnabɔli min ka bon kosɛbɛ

A bɛ Bɔ polarizasiyɔn dɔgɔyalenba la ani zeru free charges, o bɛ Labɛn ni molekiyɔmu simetri ye  ani ɛlektrɔniki sirili nɔ barikama.

·  Jateminɛ min tɛ polari ye min tɛ polari ye : Hali ni CF jɛɲɔgɔnyaw ka sigida polarite bɛ yen, fluorine atomuw labɛncogo dafalen simetri ye karɔbɔli cakɛda fan fila bɛɛ la, o bɛ na ni dipole molekiyɔmu bɛɛ lajɛlen moment ye min bɛ se zeru ma, o bɛ PTFE kɛ fɛn ye min tɛ polari ye cogoya la.

·  Elektɔron minnu sirilen don kosɛbɛ : Fluorine atomuw ka elektrɔniki-negativiti barikama bɛ ɛlektrɔni sankaba sama kosɛbɛ ka taa fluorine atomuw fan fɛ. Elektɔron minnu bɛ mɔlikuluw kɔnɔ, olu tɛ se ka wuli walima ka lafiya kɛnɛma kuran-yɔrɔ dɔ jukɔrɔ, ni charge (sara)-taama-minɛnw tɛ yen. O la, PTFE bɛ waso ni dielektriki bɔnɛ ye min ka dɔgɔ kosɛbɛ ani a ka tiɲɛni fanga ka bon.

Farankan

Kabɔn cakɛdaw sirili dafalen ni fluorine atomuw ye, CF kovalɛn jɛɲɔgɔnya surun minnu fanga ka bon, ani molekiyɔmuw labɛncogo min tɛ polari ye, o bɛ jɛ ka kɛ sababu ye ka PTFE ka baarakɛcogo danfaralenw kɛ: a tɛ nɔrɔ, a tɛ sɔgɔsɔgɔ ani a ka kuran insulation ka bon.
