Sebopeho sa Limolek'hule tsa PTFE le Thepa ea Tsona e Ntlehali

Joaloka moetsi oa profeshenale oa masela a PTFE a mocheso o phahameng, Jiangsu Aokai New Materials e u tlisetsa lintlha tsa profeshenale. Karolo ea mantlha ea lesela la mocheso o phahameng oa PTFE ke Polytetrafluoroethylene (PTFE), e nang le sebopeho sa molek'hule sa (mathbf{-(CF_2-CF_2)_n-}). Ketane e kholo ea carbon e phuthetsoe ka ho feletseng ke liathomo tsa fluorine. Lintho tsena tse tharo tse phahameng li lumellana le likarolo tsa sebopeho sa limolek'hule tsa PTFE maemong a fapaneng:

1. Thepa e ntle haholo e sa tsitsang

E tsoa ho matla a holimo a tlase haholo, a khethoang ka ho phuthela ka ntle ka ntle ha liathomo tsa fluorine  le limolek'hule tse se nang polarity..

·  Tšireletso e phahameng ea liathomo tsa fluorine: Fluorine e na le motlakase o matla ka ho fetisisa le radius e kholo ea van der Waals. Ha li hlophisitsoe khafetsa le ka bongata ka spiral lehlakoreng le ka ntle la ketane ea k'habone, liathomo tsa fluorine li etsa khetla e sireletsang e thata 'me li etsa bokaholimo bo boreleli bo nang le fluorinated ka ho feletseng.

·  Matla a fokolang a limolek'hule: Leha bond ea CF e le polar haholo, tlhophiso e lekanang ka botlalo e etsa hore ketane eohle ea molek'hule e se ke ea polar. Ke matla a fokolang feela a phasano a teng lipakeng tsa limolek'hule, a bakang matla a tlase haholo a holim'a metsi (hoo e ka bang 18 mN/m). Hoo e ka bang ha ho na lintho tse ka jalang kapa tsa khomarela bokaholimo ba PTFE.

2. Matla a Acid & Alkali Corrosion Resistance

E tsoa ho inertness ea bond e phahameng haholo ea lik'hemik'hale, e laetsoeng ke matla a phahameng a CF bond  le phello e sireletsang ea steric.

·  Libonto tsa CF tse matla haholo: Bond ea CF e na le matla a holimo-limo a bond (hoo e ka bang 485 kJ/mol), a tsitsitseng ho feta libonto tsa CH le CC, 'me ho thata haholo ho robeha.

·  Tšireletso e feletseng ea tšireletso: Khaketla e teteaneng ea athomo ea fluorine e koahela ka ho feletseng skeleton ea ketane ea carbon, e thibelang li-ion tse senyang ho kopana le ketane ea carbon e kotsing ea lik'hemik'hale. E hlokomela tšireletso ea inert ea 'mele le ea lik'hemik'hale tse peli.

3. Motlakase o Phahameng ka ho Fetisisa

E nkiloe ho polarizability e tlase haholo le litefiso tsa mahala tsa zero, tse khethiloeng ke symmetry ea molek'hule  le phello e matla ea elektronike..

·  Sebopeho sa Integral non-polar: Ho sa tsotellehe polarity ea sebaka sa CF bonds, tlhophiso e feletseng ea symmetrical ea liathomo tsa fluorine mahlakoreng ka bobeli a ketane ea carbon e fella ka nako e batlang e le zero ea dipole tsa molek'hule, ho etsa hore PTFE e be ntho e tloaelehileng e seng polar.

·  Lielektrone tse tlanngoeng ka thata-thata: Matla a motlakase a matla a liathomo tsa fluorine a hulela maru a elektrone a tiile ho ea ho liathomo tsa fluorine. Li-electrone ka har'a limolek'hule ha li khone ho falla kapa ho phomola tlas'a sebaka sa motlakase se ka ntle, ka ho hloka li-conductive charge carriers. Ka hona, PTFE e ithorisa ka tahlehelo ea dielectric e tlase haholo le matla a ho senya.

Kakaretso

Ho phutheloa ka ho feletseng ha liketane tsa carbon ka liathomo tsa fluorine, li-covalent bond tsa CF tse nang le matla a mangata, le tlhophiso ea limolek'hule tse se nang polar ka ho feletseng li kenya letsoho liketsong tse ikhethang tsa PTFE: ho se mathe, ho hanyetsa ho bola le ho kenya motlakase o phahameng.
