PTFE Molecular Structure na Ya Magburu onwe Njirimara

Dị ka onye ọkachamara na-emepụta akwa akwa okpomọkụ PTFE, Jiangsu Aokai New Materials na-ewetara gị nghọta ọkachamara. Akụkụ bụ isi nke akwa okpomọkụ dị elu nke PTFE bụ Polytetrafluoroethylene (PTFE), nwere usoro ihe omimi nke (mathbf{-(CF_2-CF_2)_n-}). Atọm fluorine kechie eriri isi carbon kpamkpam. Ngwongwo atọ ndị a dị elu kwekọrọ na atụmatụ nhazi nke ụmụ irighiri ihe PTFE na ọkwa dị iche iche:

1. Ngwongwo na-adịghị mma nke ọma

Enwetara site na ike elu dị ala, kpebisiri ike site na mkpuchi mpụta nke fluorine atom  na molecular non-polarity.

Mmetụta  nchebe dị elu nke atom fluorine: Fluorine nwere electronegativity kachasị ike na nnukwu radius van der Waals. A haziri nke ọma mgbe niile n'okirikiri dị n'akụkụ mpụta nke yinye carbon, atom fluorine na-etolite shei nchebe siri ike ma mepụta elu dị larịị zuru oke.

·  Ike intermolecular na-adịghị ike: Ọ bụ ezie na njikọ CF siri ike na polar, nhazi nke symmetrical zuru oke na-eme ka agbụ molekụla dum ghara ịbụ polar. Naanị ike mgbasa ozi na-adịghị ike dị n'etiti ụmụ irighiri ihe, na-ebute ike elu dị oke ala (ihe dịka 18 mN / m). Fọrọ nke nta ka ọ nweghị ihe nwere ike gbasaa ma ọ bụ rube isi na elu PTFE.

2. Ike Acid & Alkali Corrosion Resistance

E sitere na inertness njikọ kemịkalụ dị elu nke ukwuu, kpebisiri ike site na ike njikọ CF dị elu  yana mmetụta mkpuchi dị egwu.

Njikọ CF dị ike dị elu  : Njikọ CF na-egosipụta ike njikọ dị oke elu (ihe dị ka 485 kJ/mol), kwụsiri ike karịa njikọ CH na CC, ma sie ike ịgbaji.

Nchedo  nchebe zuru oke: shei fluorine atom na-ekpuchi skeleton nke carbon, na-egbochi ion corrosive site na ịkpọtụrụ agbụ carbon na-adịghị ike. Ọ na-achọpụta nchebe inert nke anụ ahụ na kemịkal abụọ.

3. Igwe ọkụ eletrik dị elu

Ewepụtara site na polarizability dị oke ala yana ụgwọ efu efu, kpebisiri ike site na symmetry molecular  na mmetụta njikọ elektrọn siri ike..

·  Integral na-abụghị polar Ọdịdị: N'agbanyeghị na mpaghara polarity nke CF agbụ, n'ụzọ zuru ezu symmetrical ndokwa nke fluorine atọm n'akụkụ abụọ nke carbon yinye na-arụpụta a fọrọ nke nta efu ngụkọta molekul dipole oge, na-eme PTFE a-ahụkarị na-abụghị pola ihe.

·  Eletrọn na-ekekọta nke ọma: Eletrọnegativity siri ike nke atọm fluorine na-adọta ígwé ojii nke ọma na atom fluorine. Electrons n'ime ụmụ irighiri ihe enweghị ike ịkwaga ma ọ bụ zuru ike n'okpuru ebe eletrik dị n'èzí, na-enweghị ndị na-ebu chaja. Ya mere, PTFE na-anya isi ọnwụ dielectric dị ala na ike ndakpọ dị elu.

Nchịkọta

Mkpuchi ụdọ carbon zuru oke site na atom fluorine, ike dị mkpụmkpụ CF covalent bond, na nhazi ihe omimi nke na-abụghị polar zuru oke na-enye aka na mmemme pụrụ iche nke PTFE: enweghị nrapagide, nguzogide corrosion na mkpuchi ọkụ eletrik dị elu.
