Iko kushandiswa kweyakashama fused silica capillary muEC dzimwe nguva inogona kuve isingaite nekuda kwezvisingade mhedzisiro kusanganisira adsorption yesampuli kana kusagadzikana kweEOF.Izvi zvinowanzo dziviswa nekuputira mukati mukati me capillary.Mubasa iri, tinopa uye tinoratidzira maviri matsva polyelectrolyte coatings (PECs) poly (2-(methacryloyloxy)ethyl trimethylammonium iodide) (PMOTAI) uye poly(3-methyl-1-(4-vinylbenzyl)-imidazolium chloride) (PIL- 1) kune CE.Iwo akavharidzirwa capillaries akadzidzwa pachishandiswa akatevedzana emvura mabuffers akasiyana pH, ionic simba, uye kuumbwa.Mhedzisiro yedu inoratidza kuti mapolyelectrolytes akaferefetwa anogona kushandiswa semi-permanent (pamuviri adsorbed) machira ane kanenge kashanu anomhanya kugadzikana kusati kwave kudikanwa.Ose maPEC airatidza kudzikira kwakanyanya papH 11.0.Iyo EOF yaive yakakwira ichishandisa Good's buffers pane ine sodium phosphate buffer pane imwechete pH uye ionic simba.Ukobvu hwePEC zvikamu zvakadzidzwa nequartz cry stal microbalance yaive 0.83 uye 0.52 nm yePMOTAI nePIL-1, zvichiteerana.Iyo hydrophobicity yePEC layers yakatemwa nekuongororwa kwehomologous yakatevedzana yealkyl benzoates uye yakaratidzirwa seyakagadzika yekugovera.Chigumisiro chedu chinoratidza kuti maPEC ose akanga ane hydrophobicity yakaenzana, iyo yakagonesa kuparadzaniswa kwemakemikari ne log Po / w > 2. Kukwanisa kuparadzanisa cationic mishonga yakaratidzwa ne-β-blockers, mishonga inowanzoshandiswa zvisina kunaka mu doping.Zvose zvipfeko zvakakwanisawo kuparadzanisa zvigadzirwa zve hydrolysis ye ionic liquid 1,5-diazabicyclo [4.3.0] non-5-ene acetate pamamiriro ezvinhu ane acidic, apo isina kusanganiswa silica capillaries yakakundikana kuzadzisa kupatsanurwa.
