Kuwunjikana kwa tizilombo tating'onoting'ono pamtunda ndizovuta kwa mafakitale otumizira komanso azachilengedwe.Zovala zina zodziwika bwino zothana ndi kuipitsidwa kwa polima zimawonongeka ndi okosijeni m'madzi a m'nyanja, zomwe zimapangitsa kuti zisagwire ntchito pakapita nthawi.Amphoteric ion (mamolekyu okhala ndi ndalama zoyipa komanso zabwino komanso ndalama zolipirira ukonde). za ziro) zokutira za polima, zofanana ndi makapeti okhala ndi unyolo wa polima, zakopa chidwi ngati njira zina zomwe zingatheke, koma pakali pano ziyenera kukulitsidwa m'malo opanda madzi kapena mpweya.
Gulu lotsogozedwa ndi Satyasan Karjana ku A * STAR Institute of Chemical and Engineering Sciences lapeza momwe angakonzekerere zokutira za amphoteric polima m'madzi, kutentha kwachipinda ndi mpweya, zomwe zidzawathandize kugwiritsidwa ntchito pamlingo waukulu kwambiri.
"Kunali kutulukira koopsa," akufotokoza Jana. Gulu lake linali kuyesa kupanga zokutira za amphoteric polima pogwiritsa ntchito njira yogwiritsidwa ntchito kwambiri yotchedwa atomu transfer radical polymerization, pamene anazindikira kuti zochita zina sizinapange mankhwala omwe ankafuna. Amine inapezeka mwadzidzidzi mapeto a tcheni cha polima monga ligand pa chothandizira chomwe chimagwiritsidwa ntchito pochitapo kanthu.” Kudzatenga nthawi ndi kuyesera kotsatizana kuti avumbulutse chinsinsi [cha mmene chinafikira kumeneko],” akufotokoza motero Jana.
Kuwunika kwa kinetic, nyukiliya maginito resonance spectroscopy (NMR) ndi kusanthula kwina kumasonyeza kuti ma amines amayambitsa polymerization kudzera mu njira za anion. kutsogolera gulu kukayikira zomwe apeza.Anatembenukira ku zitsanzo zamakompyuta kuti awone zomwe zikuchitika.
"Kuwerengera kwa kachulukidwe kantchito kumatsimikizira njira yopangira anionic polymerization," adatero.
Gulu lake tsopano lagwiritsa ntchito njira imeneyi kupanga zokutira za polima kuchokera ku ma monomer anayi amphoteric ndi angapo oyambitsa anionic, ena omwe si amines. pogwiritsa ntchito njira zopopera kapena zoyamwitsa, "akutero Jana. Akukonzekeranso kuphunzira za antifouling zotsatira za zokutira mu Marine ndi biomedical applications.
