Ruwan polyurethane wani sabon nau'in tsarin polyurethane ne wanda ke amfani da ruwa maimakon sinadarai masu narkewa a matsayin hanyar warwatsewa. Yana da fa'idodin rashin gurɓatawa, aminci da aminci, kyawawan halayen injiniya, dacewa mai kyau, da sauƙin gyarawa.
Duk da haka, kayan polyurethane suna fama da rashin juriyar ruwa, juriyar zafi, da juriyar narkewa saboda rashin daidaiton haɗin gwiwa.

Saboda haka, ya zama dole a inganta da kuma inganta halaye daban-daban na amfani da polyurethane ta hanyar gabatar da monomers masu aiki kamar su fluorosilicon na halitta, resin epoxy, acrylic ester, da nanomaterials.
Daga cikinsu, kayan polyurethane da aka gyara nanomaterial na iya inganta halayen injinansu sosai, juriyar lalacewa, da kwanciyar hankali na zafi. Hanyoyin gyara sun haɗa da hanyar haɗa hanyoyin haɗin gwiwa, hanyar haɗa polymerization a cikin wuri, hanyar haɗawa, da sauransu.

Nano Silica

Yana iya inganta cikakkun halayen haɗin bayan an haɗa shi da polyurethane ta hanyar haɗin covalent da ƙarfin van der Waals, kamar sassauci, juriya mai girma da ƙarancin zafin jiki, juriyar tsufa, da sauransu. Guo et al. sun haɗa polyurethane da aka gyara na nano-SiO2 ta amfani da hanyar polymerization in-situ. Lokacin da abun cikin SiO2 ya kasance kusan 2% (wt, rabon taro, iri ɗaya a ƙasa), an inganta ɗanko da ƙarfin bawon manne. Idan aka kwatanta da tsantsar polyurethane, juriya mai zafi da ƙarfin tauri suma sun ɗan ƙaru.

Nano Zinc Oxide
Nano ZnO yana da ƙarfin injiniya mai yawa, kyawawan kaddarorin ƙwayoyin cuta da ƙwayoyin cuta, da kuma ƙarfin shaƙar hasken infrared da kuma kariya daga UV mai kyau, wanda hakan ya sa ya dace da yin kayan aiki masu ayyuka na musamman.

Ƙara yawan abun ciki na nano ZnO daga 0 zuwa 5% ya ƙara zafin canjin gilashi (Tg) na polyurethane, wanda ya inganta kwanciyar hankali na zafi.

Nano Calcium Carbonate
Ƙarfin hulɗar da ke tsakanin nano CaCO3 da matrix yana ƙara ƙarfin taurin kayan polyurethane sosai. Gao da abokan aikinsa sun fara gyara nano-CaCO3 tare da oleic acid, sannan suka shirya polyurethane/CaCO3 ta hanyar polymerization a cikin wuri. Gwajin infrared (FT-IR) ya nuna cewa nanoparticles sun warwatse a cikin matrix ɗin gaba ɗaya. A cewar gwaje-gwajen aikin injiniya, an gano cewa polyurethane da aka gyara tare da nanoparticles yana da ƙarfin taurin fiye da polyurethane tsantsa.

Graphene
Graphene (G) wani tsari ne mai layi wanda aka haɗa shi da mahaɗan SP2, wanda ke nuna kyakkyawan yanayin watsawa, yanayin watsawa na zafi, da kwanciyar hankali. Yana da ƙarfi mai yawa, ƙarfin juriya mai kyau, kuma yana da sauƙin lanƙwasawa. Wu da abokan aikinsa sun haɗa nanocomposites na Ag/G/PU, kuma tare da ƙaruwar abun ciki na Ag/G, kwanciyar hankali na zafi da kuma rashin kyawun yanayin watsawa na kayan haɗin ya ci gaba da inganta, kuma aikin ƙwayoyin cuta ya ƙaru daidai gwargwado.

Nanotubes na Carbon
Na'urorin nanotubes na carbon (CNTs) nanomaterials ne masu girman gaske waɗanda aka haɗa ta hanyar hexagons, kuma a halin yanzu suna ɗaya daga cikin kayan da ke da nau'ikan aikace-aikace iri-iri. Ta hanyar amfani da ƙarfinsa mai girma, ƙarfin watsawa, da halayen haɗin polyurethane, ana iya inganta kwanciyar hankali na zafi, halayen injiniya, da kuma ƙarfin watsawa na kayan. Wu et al. sun gabatar da CNTs ta hanyar polymerization na cikin gida don sarrafa girma da samuwar ƙwayoyin emulsion, wanda ke ba da damar CNTs su warwatse a cikin matrix na polyurethane. Tare da ƙaruwar abun ciki na CNTs, an inganta ƙarfin tayar da hankali na kayan haɗin sosai.
