Polima adsorption

Adsorption ke ho khomarela ha li-ion kapa limolek'hule holim'a karolo e 'ngoe.Adsorption e ka etsahala ka physisorption le chemisorption.Li-ion le limolek'hule li ka khahla mefuta e mengata ea bokaholimo ho kenyelletsa le bokaholimo ba polymer.Polymer ke molek'hule e kholo e entsoeng ka likaroloana tse pheta-phetoang tse kopantsoeng hammoho ke li-covalent bonds.Khokahano ea li-ion le limolek'hule sebakeng sa polymer e bapala karolo lits'ebetsong tse ngata ho kenyelletsa: biomedical, structural, le coatings.

Polymerbokaholimo bo fapana ho tloha libakeng tseo e seng tsa polima ka hore li-subunits tse etsang bokaholimo li hokahane ka thata ho tse ling.Libaka tse se nang polymer li ka tlamahanngoa ke li-bond tsa ionic, li-metallic bond kapa matla a intermolecular (IMFs).Tsamaisong ea likarolo tse peli, libaka tse se nang polima li theha ha ho hlokahala matla a matle a matla ho senya litšebelisano tsa boithati le ho theha litšebelisano tse se nang boithati.Ka hona, matla a ho kopanya a ntle.Bongata bona ba matla, joalo ka ha bo hlalosoa ke tsitsipano ea sefahleho, bo fapana bakeng sa mefuta e fapaneng ea lisebelisoa.Leha ho le joalo, ka bokaholimo ba polymer, li-subunits li hokahane ka kopanelo 'me karolo e kholo ea sebaka se tiileng ha e lumelle hore tsitsipano ea bokaholimo e lekanngoe ka kotloloho.Matla a lipakeng tsa limolek'hule tse kholo tsa polymer a thata ho a bala 'me a ke ke a tsebahatsoa habonolo joalo ka litšebelisano tsa limolek'hule tse se nang polima.[2]Li-subunits tse hokahaneng ka kopanelo li theha bokaholimo bo nang le thepa e fapaneng ha e bapisoa le libaka tseo e seng tsa polima.Mehlala e meng ea bokaholimo ba polymer e kenyelletsa: polyvinyl chloride (PVC), nylon, polyethylene (PE), le polypropylene (PP).Bokaholimo ba polymer bo hlahlobiloe ho sebelisoa mekhoa e fapaneng, ho kenyelletsa: ho lekola microscope ea elektrone, ho lekola microscope, le spectroscopy ea infrared.

Libaka tse fapaneng tsa polymer li na le liketane tse fapaneng tsa mahlakoreng ho li-monomer tsa tsona tse ka lefisoang ka lebaka la papatso kapa karohano ea li-adsorbates.Ka mohlala, polystyrene sulfonate e na le li-monomers tse nang le liketane tsa mahlakoreng tse qosoang hampe tse ka khonang ho hlahisa li-adsorbate tse nang le tjhaja e ntle.Polystyrene sulfonate e tla ba adsorbate e nang le qoso e ntle ho feta e qosoang hampe.Ka lehlakoreng le leng, bakeng sa polima e nang le liketane tsa mahlakoreng tse qosoang hantle, joalo ka poly(diallyldimethylammonium chloride), li-adsorbate tse qosoang hampe li tla hoheloa haholo.

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 lintja tse sa thupeng, 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.
