Adsorption o le pipii lea o ion po'o mole mole i luga o le isi vaega.Adsorption e mafai ona tupu e ala i le physisorption ma chemisorption.O ion ma molelaula e mafai ona sosolo i le tele o ituaiga mea e aofia ai polymer surfaces.O le polymer o se mole lapo'a e fausia i vaega laiti e toe fai o lo'o fusia fa'atasi e so'o fa'atasi.O le adsorption o ions ma molecules i polymer surfaces e iai sona sao i le tele o talosaga e aofia ai: biomedical, fausaga, ma coatings.
Fa'apipi'i Fa'amau
Pa'u fa'apolotini:Protein adsorption e aʻafia ai fegalegaleaiga e tupu i le faʻaogaina o le tino-implant.O le faʻaogaina o le protein e mafai ona taʻitaʻia ai le toto, o le tali atu a le tino mai fafo ma iʻu ai i le faʻaleagaina o le masini.Ina ia mafai ona tetee atu i aʻafiaga o le faʻapipiʻiina o polotini, e masani ona faʻapipiʻiina mea faʻapipiʻi i se paʻu polymer e faʻaitiitia ai le faʻaogaina o polotini.
Polyethylene glycol (PEG) coatings ua faʻaalia e faʻaitiitia ai le faʻapipiʻiina o porotini i totonu o le tino.O le ufiufi PEG e aofia ai molelaʻau hydrophilic e faʻafefe i le faʻaogaina o porotini.O polotini e aofia ai molelaʻau hydrophobic ma nofoaga e molia ai e manaʻo e fusifusia i isi molelaʻau hydrophobic ma nofoaga faʻafeagai.E ala i le faʻaogaina o se paʻu manifinifi monolayer o le PEG, e taofia ai le faʻaogaina o le polotini i le nofoaga o masini.E le gata i lea, o le teteʻe o le masini i le adsorption protein, faʻapipiʻi fibroblast ma faʻapipiʻi siama ua faʻateleina.
Lauga antithrombogenic:O le hemocompatability o se masini fa'afoma'i e fa'alagolago i luga ole tau, malosi ma fa'afanua.O masini e le mafai ona fa'aogaina le hemocompatabile e ono tula'i mai ai se thrombus, fa'atuputeleina ma fa'aletonu ai le tino puipuia.O lo'o fa'aogaina le polymer coatings i masini e fa'ateleina ai lo latou fa'aogaina o le hemocompatability.O vailaʻau faʻamaʻi e taʻitaʻia ai le faʻatupuina o fibrous clots.E ala i le filifili e faʻaoga le hydrophilic polymer coatings, e faʻaitiitia ai le faʻaogaina o porotini ma faʻaitiitia ai foi le avanoa o fegalegaleaiga le lelei ma le toto.O se tasi o mea faʻapipiʻi polymer e faʻateleina ai le hemocompatability o le heparin.Heparin o se polymer coating e fegalegaleai ma le thrombin e puipuia ai le coagulation.O le Heparin ua faʻaalia e taofiofia le pipii o platelet, faʻamalosia le faʻagaoioia ma le faʻaogaina o porotini.
Fa'atulagaina
Fa'apipi'i polymer maualuluga:O loʻo faʻaaogaina polymer composites i le faʻamalosia ma le toe faʻaleleia o fausaga tuai.O nei mea fa'apipi'i maualuga e mafai ona faia i le tele o metotia eseese e aofia ai prepreg, resin, infusion, filament winding ma pultrusion.O mea fa'apipi'i polymer fa'apitoa e fa'aaogaina i le tele o fausaga o va'alele ma o latou maketi tele o lo'o i le vateatea ma le puipuiga.
polymers fa'amalosia alava:Fiber-reinforced polymers (FRP) e masani ona faʻaaogaina e inisinia sivili i totonu o latou fausaga.FRPs tali laina-elastically i axial stress, avea i latou ma mea sili e uu ai se uta.FRPs e masani lava ona fa'apipi'iina ma lamina ta'itasi e iai alava e tasi, e masani lava o le kaponi po'o le tioata, fa'apipi'i i totonu o se vaega o mea mama matrix polymer.FRPs e malosi tele le tetee atu i le faʻaalia o le siosiomaga ma le umi tele.
Polytetrafluoroethylene:Polytetrafluoroethylene (PTFE) o se polymer e faʻaaogaina i le tele o talosaga e aofia ai mea e le faʻapipiʻiina, mea matagofie, ma lubricants.PTFE o se mole mole hydrophobic e aofia ai carbon ma fluorine.O fusi o le carbon-fluorine e mafua ai le avea o le PTFE ma mea e maualalo le feteʻenaʻi, faʻaogaina i siosiomaga vevela maualuga ma faʻafefe i le faʻalavelave faʻalavelave.O nei meatotino e mafua ai le PTFE e le faʻaalia ma faʻaaogaina i le tele o faʻaoga.
Polymer adsorption i ala o faasalalauga porous:O le faʻaogaina o le tino ma le faʻaogaina o masini e lua mafuaʻaga autu o le taofiofia o polymer i ala o faasalalauga porous.O le taofiofia o polymer maualalo i totonu o le faatanoa e taua tele mo le manuia o le faʻaogaina o le polymer EOR.
