Kuunganidzwa kwezvipembenene zviri pamusoro idambudziko kune ese maindasitiri ekutakura uye ebiomedical.Mamwe akakurumbira anti-pollution polymer coatings anosangana neoxidative degradation mumvura yegungwa, zvichiita kuti asashande nekufamba kwenguva.Amphoteric ion (mamorekuru ane zvakaipa uye zvakanaka mhosva uye net charge ye zero) machira epolymer, akafanana nemakapeti ane cheni dzepolymer, akakwezva kutarisa sezvingangoitwa dzimwe nzira, asi pari zvino anofanira kurimwa munzvimbo inert isina mvura kana mhepo.
Chikwata chinotungamirwa naSatyasan Karjana kuA * STAR Institute of Chemical and Engineering Sayenzi chakawana nzira yekugadzira amphoteric polymer coatings mumvura, tembiricha yemukamuri uye nemhepo, izvo zvinozoita kuti ishandiswe pachiyero chakakura.
"Kwaiva kuwanikwa kunotyisa," anotsanangura kudaro Jana. Boka rake rakanga richiedza kugadzira amphoteric polymer coatings vachishandisa nzira inoshandiswa zvakanyanya inonzi atom transfer radical polymerization, pavakaona kuti mamwe maitiro haana kuburitsa chigadzirwa chaidiwa. Amine yakawanikwa zvisingatarisirwi kuguma kwecheni yepolymer sechitsigiro chiri pachinhu chinoshandiswa mukuita.” Zvinotora nguva yakati nenhevedzano yekuedza kuburitsa chakavanzika [chekuti chakasvika sei ikoko],” anotsanangura kudaro Jana.
Kinetic observations, nuclear magnetic resonance spectroscopy (NMR) uye kumwe kuongorora kunoratidza kuti maamines anotanga polymerization kuburikidza neanion mechanisms. Aya anonzi anionic polymerizations haagadziriswi nemvura, methanol, kana mhepo, asi mapolymers aJana akakura pamberi pehutatu hwose. zvichiita kuti timu isava nechokwadi nezvavakawana.Vakatendeukira kumhando dzemakombiyuta kuti vaone zvaiitika.
"Density functional theory calculations inosimbisa iyo yakarongwa anionic polymerization mechanism," akadaro.
Chikwata chake chave kushandisa nzira iyi kugadzira machira epolymer kubva kune ina amphoteric monomers uye akati wandei eanionic ekutanga, mamwe acho asiri maamine. kushandisa spray kana impregnation nzira, "Jana anoti.Vanorongawo kudzidza nezve antifouling migumisiro yekuputira muMarine uye biomedical applications.
