Okuziyiza okuseeyeeya n’okunyweza okumala ebbanga eddene okw’olutambi lwa Teflon olw’ebbugumu ery’amaanyi olukwata waggulu biyinza bitya okulongoosebwa?

I.MolecularNetworkTopologyOptimizationoftheSiliconeAdhesiveLayer–Okulongoosa obuziyiza bwa BulkCreep

1.HighMQResin / SiliconeRubberRatioand 'Ekikalu-Core ' Enzimba

Abakola bakwata MQsiliconeremu nga coretackifier era n’ekirungo ekinyweza, okwongera ku MQ/gumratioto1.2:1–2:1(esinga nnyo ku ddaala erya bulijjo).ThishighMQratioformcontinuous rigid'hard-phase'microdomainwithinheadhesivelayer, eziziyiza okutambula kwa siloxanechainsgments era zirongoosa nnyo modulo y'okutereka era nga ziziyiza ebbugumu erigulumivu.

2.Okuyingiza ebibinja ebikalu ebigumira ebbugumu n’ebifo ebiyunga amasoboza aga waggulu

Ebibinja bya phenyl,diphenyl, oba carboranebiyingizibwa mu mugongo gwa polydimethylsiloxane(okugeza, 20–30mol%phenyl contentt)okuziyiza entambula y’olujegere lw’ebbugumu n’okusitula ebbugumu ly’okutambula kw’endabirwamu n’okusitula rmaldecompositiontemperature.Enkola y’okuyunga esinga kukozesa kugatta-okuwonya amazzi (Pt-catalyzed), okukola–C–C–oba–Si–C–okusala omutala n’obutebenkevu obw’ebbugumu obw’oku ntikko.

3.OkufugaObuzito bwa MolekyuluWakati w’Ebikwatagana (Mc) n’Ebikyamu ku Mutimbagano

Nga tutereeza obulungi ebirimu haidrojeni ekola n’obuwanvu bw’olujegere olwa silikoni erimu haidrojeni, Mc ntono nnyo era nga 5,000–15,000g/mol) etuukiddwako, okukakasa nti akatimba omulimu gukuuma obugumu obusingako mu bbugumu ery’amaanyi.Ekigaziyiziddwa oluvannyuma lw’okuwonya oba ebbugumu erya waggulu kiweebwayo ku bibinja ebisigadde ebiddamu ebikozesa n’okukendeeza okuwummuzibwa okw’okunyigirizibwa okuleetebwa obulema ku mutimbagano.

III.Ebijjuza NanoOkuzimbaOkuyungibwa kw’Eby’Omubiri n’Amagumba Agagumira Ebbugumu

1.Okunyweza mu kifo n’okukyusakyusa kungulu kwa Nano-Silica

Abakola bakola silika ow’omukka (ekitundu ekigere ku ngulu200–380m²/g), okulongoosebwa kungulu ne vinyltriethoxysilane oba hexamethyldisilazane, okutikka 10–25wt%.Thenano-SiO2 ekola ebiyungo bya haidrojeni n’okusikiriza okw’omubiri n’enjegere za siloxane, ne zitonda reversiblephysicalcrosslinkingnetwork that dissipatesenergyand prevents molecularchains slippageathight temperatures.Okusaasaana okw'okusala okw'amaanyi kukakasa nti silika eriwo'ebibinja'nga ebinene ebinene wansi wa 100nm, okwewala okusengejja situleesi.

2.Obuziyiza obw’obulagirizi nga buyita mu2DNanomaterials

Okwongerako 1–5wt%few-layergraphene obaorgano-modifiednano-montmorillonite, nga etunudde mu layeridaranrangement okuyita mu shear-induced alignment mu kiseera ky'okusiiga, kikola 'mazeeffect'paralleltothetapep lane,kwongera nnyo obuziyiza ku ntambula y’olujegere lwa molekyu mu kusala.

IV.Ekigattibwa mu ddagalaSubstrate–AdhesiveInterfaceandProcessControl

1.Okukola ku ngulu nePrimer ow’emirimu ebiriforChemicalBonding

Ensimbi za PTFE esooka kulongoosebwa n’ekizimbulukusa kya sodium–naphthalene–THF oba argon/oxygenplasma eya puleesa entono okukola layeri ekoleddwa erimu ebibinja bya carboxylandhydroxyl.Ekisengejjero kya aprimer ekirimu molekyu ezikola bibiri (okugeza, isocyanatesilane, titanatecouplinggent+epoxysilane)kiba kya mangu ddala ated.Omu ku primerekola ne–OH/–COOHkuPTFEsurface, ate nga endala enkomerero yeetaba mu hydrosilylation oba condensation crosslinking ne siliconeadhesive, ekola omukutu gwa kemiko oguyingira mu interface.Enkola eno esobola okwongera ku maanyi agakwata ebbugumu erya waggulu(ku 260°C) emirundi 3–5.
