Me pehea e pai ake ai te aukati ngoki me te pumau mo te wa roa o te rīpene Teflon-nui-te-te-te-mahana?

I.MolecularNetworkTopologyOptimizationoftheSiliconeAdhesiveLayer–Te whakapai ake i te Aatete Kirito

1.HighMQResin/SiliconeRubberRatioand'Hard-Core' Hanganga

Ko te hangahanga MQsiliconere ka rite ki te kaikokoti matua me te maataki whakakaha, te whakanui ake i te MQ/gumratioto1.2:1–2:1(tino teitei ake i nga tohu tikanga). mārō'waa-waahanga'microdomains i roto i te whakakikorua mahunga, e whakararu ana i te nekenga o nga wahanga o te hioxane me te whakapai ake i te whakamohoatanga rokiroki me te tuunga kirikiri i nga pāmahana.

2.Te Kaporeihana o nga RoopuMaiti me te Hinga-hononga-Teitei-Te-Hana

Phenyl, diphenyl, carborane groupe ka whakaurua ki roto i te polydimethylsiloxane backbone(hei tauira, 20–30mol%phenyl content) ki te arai i te mekameka werawera me te whakanui i te pāmahana whakawhiti karaihe me te rmaldecompositiontemperature.Thecrosslinkingsystempreferentiallyemploysaddition-curehydrosilylation(Pt-catalyzed), hanga–C–C–ranei–Si–C–crosslinkingbridges with superiorthermalstability.

3.Te Mana o te Taumaha MolecularI waenganui i nga Hononga Whakawhiti(Mc)me nga Hapa Whatunga

Ma te tika te whakatikatika i te ihirangi hauwai hohe me te roanga mekameka o te hinu hilikakono kei roto i te hauwai, he ahua iti te ahuaMc(tata ki te 5,000–15,000g/mol) kua tutuki, kia mohio kei te kupenga Ka mau tonu te kaha o te mahi ahakoa te kaha o te pamahana.Ko te whakamaarama i muri i te whakamaroketanga, i te werawera-tiketike ranei ka whakamahia ki te kai i te toenga o te roopu hohekoheko me te whakangawari i te whakangawaritanga i puta mai i nga hapa o te mahi.

III.Nanowhakakii mo te Hanga-Tino-Tinohonohononga me te Anga-Wea

1.In-SituReinforcementandSurfaceModificationofNano-Silica

Ko te hangahanga he hinuhuka (waahanga mata motuhake200–380m²/g), te mata-whakaritea ki te vinyltriethoxysilaneorhexamethyldisilazane ranei, te utaina o te 10–25wt%.Thenano-SiO₂ka hangai i nga here hydrogenbonds me te whakaurunga tinana me nga mekameka hioxane. Ko te whatunga hono-a-tinana ka taea te huri i te kaha me te aukati i nga mekameka kapoipoi te wharangi karekau.Ko te whakamararatanga kutikuti teitei ka tino mohio kei te noho te hilika hei 'pupuu' me te whakaemi i raro iho i te 100nm, ka karo i te kukū o te ahotea.

2.DirectionalCreepResistancevia2DNanomaterials

Tāpiritanga o te 1–5wt% torutoru-paparanga-raupapa-whakarereke-whakarereke-nano-montmorillonite, e whakahoa ana ki te whakatakotoranga i roto i te kutikuti-whakaarohia i roto i te whakakikoruatanga, te ahua'mazeeffect' whakarara ki te rīpene ara, ka tino piki ake te aatete ki roto i te nekehanga o te mekameka hiko i roto i te ahunga kutikuti.Ka taea e te kauwhata te tuku i te pai o te kawenga-wera, te whakaiti i nga waahi wera i roto i te whao piri me te whakaroa i te ngaariki.

IV.Te Whakakotahi Maamaa–Atanga Whakapiri me te Mana Whakahaere

1.SurfaceActivationandBifunctionalPrimerforChemicalBonding

Ko te mata o te PTFE ka mahi tuatahi ma te konupora–naphthalene–THFsolutionor iti-pressureargon/oxygenplasmatogenerate-whakahoahoa te paparanga kei roto he carboxylandhydroxylgroups.Aprimersolutioncontaining bifunctionalmolecules(hei tauira,isocyanatesilane,titanatecoplingagent+epoxymediatelyco)isthenim Ka tauhohe tetahi pito o te tuatahi ki–OH/–COOHi runga i te mata o te PTFE, ko tetahi atu ka uru ki roto i te hydrosilylation, te whakamaaramatanga ranei e hono ana ki te pirikoko, ka hanga he hononga matū e kuhu ana ki te atanga.Ka taea e tenei huarahi te whakanui ake i te mana pupuri i te pāmahana teitei(i te 260°C).

2.RampedCuringandPost-TreatmenttoEliminateDefects

Ka mahihia: tuatahi, ka peia te whakarewa me te papanga whakapiri ka whakatauritea ki te 80–100°C; katahi ka whakahiatohia me te whakakakahu o MQresina ka oti i te 150–170°C; ka mutu, whakairihia -Ka rongoa i waho i te 200–220°C mo etahi haora hei whakakore i te ahotea o roto me te whakapumau i nga waahi hono-a-tinana.Te whakamatao puhoi ka arai i te ngatata o te miihini ki te whakahekenga wera rereke.
