Ulwakhiwo lweMolekyuli ye-PTFE kunye neempawu zayo ezigqwesileyo

Njengomvelisi womthombo oqeqeshiweyo wamalaphu obushushu obuphezulu be-PTFE, i-Jiangsu Aokai New Materials ikuzisela ulwazi lobungcali. Inxalenye ephambili yelaphu le-PTFE lobushushu obuphezulu yiPolytetrafluoroethylene (PTFE), kunye nesakhiwo semolekyuli ye- (mathbf{-(CF_2-CF_2)_n-}). Ikhonkco eliphambili lekhabhoni lisongelwe ngokupheleleyo ziiathom zefluorine. Ezi zakhiwo zintathu ziphezulu zihambelana neempawu zesakhiwo seemolekyuli ze-PTFE kumanqanaba ahlukeneyo:

1. IPropati egqwesileyo eNgenantonga

Ithatyathwe kumandla asezantsi asezantsi kakhulu, agqitywe kukusonga kwangaphandle okuqinileyo kweeathom zefluorine  kunye nemolekyuli engeyiyo ipolarity..

·  Ukhuseleko oluphezulu lwempembelelo yeeathom zefluorine: I-Fluorine inee-electronegativity eyomeleleyo kunye neradius enkulu ye-van der Waals. Rhoqo nangokuxineneyo zicwangciswe kwi-spiral kwicala langaphandle letsheyina lekhabhoni, iiathom zefluorine zenza iqokobhe elikhuselayo eliqinileyo kwaye lenze umphezulu ogudileyo ogudileyo.

·  Amandla e-intermolecular abuthathaka: Nangona i-CF bond iqine kakhulu kwi-polar, ilungiselelo elilinganayo ngokupheleleyo linika lonke ikhonkco le-molecular non-polar. Kukho amandla okusasazwa abuthathaka kuphela akhoyo phakathi kweeathom, okukhokelela kumandla aphantsi kakhulu kumphezulu (malunga ne-18 mN/m). Phantse akukho zinto zinokusasazeka okanye zibambelele kumphezulu we-PTFE.

2. I-Acid eyomeleleyo kunye ne-Alkali yokuNxina nokuCorrosion

Ithatyathwe ekungangeni kwibhondi yekhemikhali ephezulu kakhulu, egqitywe ngamandla e-CF ephezulu yebhondi  kunye nefuthe elikhuselayo..

·  Iibhondi ze-CF eziphezulu: I-CF bond ibonisa amandla ebhondi e-ultra-high (malunga ne-485 kJ / mol), izinzile kakhulu kune-CH kunye ne-CC bond, kwaye kunzima kakhulu ukuyiqhawula.

·  Ukhuseleko olupheleleyo lokhuselo: Iqokobhe elishinyeneyo leathom yefluorine ligquma ngokupheleleyo ithambo letsheyina lekhabhoni, lithintela ii-ion ezidlekayo ekudibaneni netsheyina lekhabhoni elisemngciphekweni. Iqaphela ukukhuselwa okubili komzimba kunye neekhemikhali.

3. I-Superior Electrical Insulation

Ithatyathwe kwi-polarizability ephantsi kakhulu kunye ne-zero yentlawulo yasimahla, egqitywe yi- symmetry yemolekyuli  kunye nefuthe elinamandla lokubopha i-electron..

·  Ulwakhiwo oludityanisiweyo olungelulo lwepolar: Ngaphandle kwepolarity yasekhaya yeebhondi zeCF, ulungelelwaniso olulungeleleneyo ngokupheleleyo lweeathom zefluorine kumacala omabini ekhonkco lekhabhon liphumela kumzuzu ophantse ube nguziro wemolekyuli ye-dipole, eyenza i-PTFE ibe yimathiriyeli engeyo-polar eqhelekileyo.

·  Ii-elektroni ezibotshelelwe ngokuqinileyo: I-electronegativity eyomeleleyo yeeathom zefluorine zitsala amafu e-electron ngokuthe nkqi ukuya kwiiathom zefluorine. Ii-electron ngaphakathi kwee-molecule azikwazi ukufuduka okanye ukuphumla phantsi kwendawo yombane yangaphandle, kunye nokungabikho kwabathwali bentlawulo yokuqhuba. Ke ngoko, i-PTFE inelahleko ephantsi ye-dielectric kunye namandla okuqhekeka okuphezulu.

Isishwankathelo

Ukusongwa ngokupheleleyo kwamatyathanga ekhabhoni ngeeathom zefluorine, iibhondi eziqinileyo ezimfutshane zeCF eziphezulu, kunye nolungelelwaniso olupheleleyo lwemolekyuli engeyiyo ipolar ngokudibeneyo negalelo kwimisebenzi eyahlukileyo ye-PTFE: ukungabambeki, ukuxhathisa ukubola kunye nokugqunywa kombane okuphezulu.
