Ukuqokelelwa kwee-microorganisms kumphezulu ngumngeni kuzo zombini iinqanawa kunye ne-biomedical industries.Ezinye iipolymer ezithandwayo ezichasene nongcoliseko zenziwa ukuthotywa kwe-oxidative emanzini olwandle, okwenza ukuba zingasebenzi ngokuhamba kwexesha.I-ion ye-amphoteric (iamolekyuli ezineentlawulo ezingalunganga kunye nexabiso eliphantsi of zero) iicolymer coatings, ezifana neekhaphethi ezinemixokelelwane yepolymer, zitsale ingqalelo njengezinye ezinokuthi zibekho, kodwa okwangoku kufuneka zikhuliswe kwindawo engasebenziyo ngaphandle kwamanzi okanye umoya.Oku kuzithintela ekusebenziseni kwiindawo ezinkulu.
Iqela elikhokelwa nguSatyasan Karjana kwi-A * STAR Institute of Chemical and Engineering Sciences lifumene indlela yokulungisa iingubo ze-polymer ze-amphoteric emanzini, ukushisa kwegumbi kunye nomoya, okuya kwenza ukuba zisetyenziswe kwi-A lot wider scale.
Iqela lakhe lalizama ukwenza i-amphoteric polymer coatings ngokusebenzisa indlela esetyenziswa ngokubanzi ebizwa ngokuba yi-atom transfer radical polymerization, xa bafumanisa ukuba ezinye iintshukumo azizange zivelise imveliso efunekayo. I-amine yafunyanwa ngokungalindelekanga isiphelo setsheyina lepolymer njengeligand kwi-catalyst esetyenziswa ekuphenduleni.” Kuya kuthabatha ixesha nongcelele lwemifuniselo ukuze kutyhilwe imfihlelo [yendlela eyafika ngayo apho],” ucacisa ngelitshoyo uJana.
Ukuqwalaselwa kwe-Kinetic, i-nuclear magnetic resonance spectroscopy (NMR) kunye nolunye uhlalutyo lubonisa ukuba ii-amines ziqalisa i-polymerization ngokusebenzisa iindlela ze-anion. ekhokelela iqela ukuba lithandabuze iziphumo zalo.Baphendukela kwiimodeli zekhompyuter ukuze babone ukuba kwenzeka ntoni.
"Ubalo lwethiyori yoxinaniso luqinisekisa indlela ecetywayo ye-anionic polymerization," utshilo.
Iqela lakhe ngoku lisebenzise le ndlela ukwenza i-polymer coatings ukusuka kwiimonomer ezine ze-amphoteric kunye nenani labaqalisi be-anionic, ezinye zazo ezingezizo ii-amines. usebenzisa iindlela zokutshiza okanye zokufakela, "utsho uJana. Kwakhona baceba ukufunda imiphumo echasene ne-antifouling yeengubo kwi-Marine kunye ne-biomedical applications.
