Liaparo tsa ho kenyetsa
Liaparo tse hanyetsanang le protheine:Protein adsorption e susumetsa litšebelisano tse etsahalang sebopehong sa li-tissue-implant.Protein adsorption e ka lebisa maling a mali, karabelo ea 'mele oa kantle ho naha mme qetellong ho senyeha ha sesebelisoa.Bakeng sa ho loantša litlamorao tsa protheine adsorption, li-implants hangata li koahetsoe ka polymer e koahelang ho fokotsa protheine adsorption.
Liaparo tsa polyethylene glycol (PEG) li bontšitsoe ho fokotsa ho ba le protheine 'meleng.Seaparo sa PEG se na le limolek'hule tsa hydrophilic tse nyonyehang ho protheine adsorption.Liprotheine li na le limolek'hule tsa hydrophobic le libaka tsa tefiso tse batlang ho tlama limolek'hule tse ling tsa hydrophobic le libaka tse fapaneng tse qosoang.Ka ho sebelisa seaparo se tšesaane sa monolayer sa PEG, protheine adsorption e thibeloa sebakeng sa lisebelisoa.Ho feta moo, khanyetso ea sesebelisoa ho adsorption ea protheine, fibroblast adhesion le ho khomarela libaktheria lia eketseha.
Liaparo tsa antithrombogenic:Thehello ea mali ea sesebelisoa sa bongaka e ipapisitse le tefiso ea bokaholimo, matla le topography.Lisebelisoa tse hlolehang ho ba hemocompatabile li kotsing ea ho theha thrombus, ho ata le ho senya sesole sa 'mele.Liaparo tsa polymer li sebelisoa ho lisebelisoa ho eketsa bokhoni ba tsona ba ho ba le hemocompatability.Li-cascade tsa lik'hemik'hale li lebisa ho thehoeng ha li-fibrous clots.Ka ho khetha ho sebelisa liphahlo tsa hydrophilic polymer, protheine adsorption ea fokotseha mme monyetla oa ho sebelisana hampe le mali oa fokotseha.E 'ngoe ea litlolo tse joalo tsa polymer tse eketsang hemocompatability ke heparin.Heparin ke seaparo sa polymer se sebetsanang le thrombin ho thibela ho kopana.Heparin e bontšitsoe ho hatella ho khomarela platelet, ho tlatsana le ts'ebetso le protheine adsorption.

Likarolo tse tsoetseng pele tsa polymer:Li-composites tse tsoetseng pele tsa polymer li sebelisoa ho matlafatsa le ho tsosolosa mehaho ea khale.Likarolo tsena tse tsoetseng pele li ka etsoa ka mekhoa e mengata e fapaneng ho kenyelletsa prepreg, resin, infusion, filament winding le pultrusion.Li-composites tse tsoetseng pele tsa polymer li sebelisoa meahong e mengata ea lifofane mme 'maraka oa tsona o moholo o sebakeng sa sefofane le ts'ireletso.
Li-polymers tse matlafalitsoeng ka fiber:Li-polymers tse matlafalitsoeng ka fiber (FRP) hangata li sebelisoa ke baenjiniere ba sechaba meahong ea bona.Li-FRP li arabela ka mokhoa o tsitsitseng ho khatello ea axial, e leng se etsang hore e be thepa e kholo ea ho tšoara mojaro.Li-FRP hangata li entsoe ka laminate le lamina e 'ngoe le e' ngoe e nang le likhoele tse sa tšoaneng, hangata k'habone kapa khalase, e kentsoeng ka har'a lesela la matrix a polymer e khanyang.Li-FRP li na le khanyetso e kholo khahlanong le ho pepeseha ha tikoloho le ho tšoarella ho hoholo.
Polytetrafluoroethylene:Polytetrafluoroethylene (PTFE) ke polymer e sebelisoang lits'ebetsong tse ngata ho kenyeletsoa liaparo tse sa roaloang, lihlahisoa tsa botle le mafura.PTFE ke molek'hule ea hydrophobic e entsoeng ka carbon le fluorine.Litlamo tsa carbon-fluorine li etsa hore PTFE e be thepa e fokolang e fokolang, e loketseng maemo a mocheso o phahameng le e hanyetsanang le khatello ea maikutlo.Lintho tsena li etsa hore PTFE e se ke ea sebetsa 'me e sebelisoe mefuteng e mengata ea lits'ebetso.
Polima adsorption mecheng ea litaba ea porous:Papatso ea 'mele le ho ts'oaroa ka mochini ke lisosa tse peli tse kholo tsa ho bolokoa ha polymer mecheng ea litaba tse porous.Ho boloka polima e tlase ka letamong ho bohlokoa molemong oa katleho ea ts'ebetso ea polymer EOR.
