Ko te hanga i te MQsiliconere ka rite ki te kaitapaa 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 nga mekameka me te tino whakapai ake i te waahanga rokiroki me te whakahaerenga kirikiri i nga pāmahana.
Phenyl, diphenyl, carborane groupe ka whakaurua ki roto i te polydimethylsiloxane backbone (hei tauira, 20–30mol%phenyl content) ki te aukati i te mekameka wera me te whakanui i te pāmahana whakawhiti karaihe me te rmaldecompositiontemperature.He pai ake te whakamahi i te punaha hono-whakawhitinga-whakaora-whakawai(Pt-catalyzed), te hanga–C–C–ranei–Si–C–piriti whakawhiti me te tino ngaawera.
Ma te tika te whakatikatika i te ihirangi hauwai hohe me te roanga mekameka mo te hinu-hinu-a-waikawa, he ahua iti te ahuaMc(tata ki te 5,000–15,000g/mol) kua tutuki, me te whakarite 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-teitei ranei ka whakamahia ki te kai i te toenga o te roopu hohekoheko me te whakangawari i te whakangawaritanga na roto i nga hapa o te mahi.

Ko te hangahanga he hinuhuka (waahanga mata motuhake200–380m²/g), te mata-whakaritea ki te vinyltriethoxysilaneorhexamethyldisilazane, te utaina o te 10–25wt%.Thenano-SiO₂ka hanga i nga here hydrogenbonds me te whakaurunga tinana me nga mekameka whakangao-a-tinana. Ko te whatunga hono-a-tinana ka huri ka memeha te kaha me te aukati i nga mekameka kapoipoi te wharangi karekau.Ka tino mohio te marara kutikuti teitei ka noho te hilika hei 'pupuu' me te rahi o te kohinga i raro i te 100nm, ka karo i te kukū o te ahotea.
Tāpiritanga o te 1–5wt% torutoru-paparanga-whakarereke-whakarereke-nano-montmorillonite, e whakahoa ana ki te whakatakotoranga i roto i te tirohanga kutikuti i roto i te whakakikoruatanga, te ahua'mazeeffect'paralleltothetapep ara, ka tino piki ake te aatete ki te hikoi hikoi i roto i te kutikuti.
Ko te mata o te PTFE ka mahi tuatahi ma te konupora–naphthalene–THFsolutionor iti-pressureargon/oxygenplasmatogenerate-whakahoahoa paparanga kei roto i te carboxylandhydroxylgroups.Aprimersolutioncontaining bifunctionalmolecules(hei tauira,isocyanatesilane,titanatecouplingagent+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 whakapiripiri-silicone, ka hanga he hononga matū e kuhu ana ki te atanga. Ko tenei huarahi ka taea te whakanui ake i te mana pupuri i te pāmahana teitei (ma te 260°C).
Ka mahihia: tuatahi, ka peia te whakarewa me te papanga whakapiri ka whakataurite ki te 80–100°C; katahi ko te whakamaaramatanga me te whakakoi i te MQresina ka oti i te 150–170°C; ka mutu, whakairihia -Ka rongoa i waho i te 200–220°C mo nga haora maha hei whakakore i te ahotea o roto me te whakau i nga tohu hono-a-tinana.Te whakamatao puhoi ka arai i te ngatata o te miihini ki te whakahekenga wera rereke.
