Wehe kēia hana polymerization hou i ka puka i nā pale antifouling hou aʻe

ʻO ka hōʻuluʻulu ʻana o nā microorganism ma ka ʻili kahi pahuhopu no nā ʻoihana hoʻouna a me nā biomedical. ʻO kekahi mau pale polymer anti-haumia i hoʻoliʻiliʻi i ka hoʻohaʻahaʻa oxidative i ka wai kai, e hana ʻole ana i ka manawa. Amphoteric ion (nā molaki me nā koina maikaʻi ʻole a maikaʻi a me ka uku net o nā zero) nā uhi polymer, e like me nā kapeta me nā kaulahao polymer, ua ʻumeʻaka ka nānā ʻana ma ke ʻano he koho ʻē aʻe, akā pono e ulu i kēia manawa i kahi wahi inert me ka ʻole o ka wai a me ka ea. Pale kēia iā lākou mai ka hoʻopili ʻana i nā wahi nui.

ʻO kahi hui i alakaʻi ʻia e Satyasan Karjana ma ka A * STAR Institute of Chemical and Engineering Science ua ʻike pehea e hoʻomākaukau ai i nā uhi polima amphoteric i ka wai, ka mahana o ka lumi a me ka ea, e hiki ai iā lākou ke hoʻohana ma kahi pālākiō nui loa.

"He loiloi serendipitous kēia," i wehewehe ai ʻo Jana. Ke hoʻāʻo nei kāna hui e hana i nā uhi polima amphoteric me ka hoʻohana ʻana i kahi hana i hoʻohana ʻia i kapa ʻia ʻo atom transfer radical polymerization, ke ʻike lākou ʻaʻole kekahi mau hopena i hoʻopuka i ka huahana i makemake ʻia. ka hopena o ke kaulahao polymer ma ke ʻano he ligand ma ka catalyst i hoʻohana ʻia i loko o ka hopena. "E liʻuliʻu ka manawa a me kahi mau hoʻokolohua e wehe ai i ka mea pohihihi [pehea i hiki ai ma laila]," wehewehe ʻo Jana.

Kuhi nā ʻike kinetic, spectroscopy magnetic resonance magnet (NMR) a me nā anamana ʻē aʻe e hoʻomaka nā amine i ka polymerization ma o nā ʻano anion. ʻAʻole kūʻē kēia mau polyterization anionic i ka wai, methanol, a me ka ea, akā ua ulu nā polymers o Jana i mua o nā mea ʻekolu. ke alakaʻi nei i ka hui e kānalua i kā lākou loaʻa. Ua huli lākou i nā hiʻohiʻona kamepiula e ʻike i nā mea e hana nei.

"ʻO ka helu ʻana o nā kumumanaʻo kumumanaʻo pilikino e hōʻoia ana i ka hana polythision anionic i manaʻo ʻia," i ʻōlelo ʻo ia. "ʻO kēia kahi hiʻohiʻona mua loa o kahi polythisation solution anionic o nā monomers ethylene i loko o kahi wai wai ma lalo o nā kūlana aerobic."

Ua hoʻohana kāna kime i kēia hana i synthesise polymer coatings mai ʻehā monomers amphoteric a me kekahi o nā anionic initiators, kekahi o lākou ʻaʻole amine. "I ka wā e hiki mai ana, e hoʻohana mākou i kēia hana e hana i nā papa polymer biofilt-resistant i nā ʻāpana nui. me ka hoʻohana ʻana i ka spray a me nā impregnation, "i ʻōlelo ʻo Jana. Hoʻolālā pū lākou e hoʻopaʻa i nā hopena antifouling o nā uhi ma nā noi kai a me nā biomedical.
