I-polyurethane ephuma emanzini luhlobo olutsha lwenkqubo ye-polyurethane esebenzisa amanzi endaweni yezinyibilikisi zendalo njengendlela yokusasaza. Inezibonelelo zokungangcolisi, ukhuseleko kunye nokuthembeka, iipropati ezintle kakhulu zoomatshini, ukuhambelana okuhle, kunye nokuguqulwa okulula.
Nangona kunjalo, izinto ze-polyurethane nazo zinengxaki yokumelana namanzi kakuhle, ukumelana nobushushu, kunye nokumelana nesinyibilikisi ngenxa yokungabikho kweebhondi ezizinzileyo zokudibanisa.

Ngoko ke, kuyimfuneko ukuphucula nokuphucula iipropati ezahlukeneyo zokusetyenziswa kwe-polyurethane ngokungenisa ii-monomers ezisebenzayo ezifana ne-organic fluorosilicone, i-epoxy resin, i-acrylic ester, kunye ne-nanomaterials.
Phakathi kwazo, izinto ze-polyurethane eziguqulwe yi-nanomaterial zinokuphucula kakhulu iipropati zazo zoomatshini, ukumelana nokuguguleka, kunye nokuzinza kobushushu. Iindlela zokuguqula ziquka indlela ye-intercalation composite, indlela ye-in-situ polymerization, indlela yokuxuba, njl.

I-Nano Silica
I-SiO2 inesakhiwo senethiwekhi esinemilinganiselo emithathu, kunye nenani elikhulu lamaqela e-hydroxyl asebenzayo kumphezulu wayo. Ingaphucula iipropati ezipheleleyo ze-composite emva kokuba idityaniswe ne-polyurethane nge-covalent bond kunye ne-van der Waals force, ezifana nokuguquguquka, ukumelana nobushushu obuphezulu nobuphantsi, ukumelana nokuguga, njl. UGuo et al. badibanise i-nano-SiO2 modified polyurethane besebenzisa indlela ye-in-situ polymerization. Xa umxholo we-SiO2 wawumalunga ne-2% (wt, mass fraction, efanayo ngezantsi), i-shear viscosity kunye namandla e-peel e-adhesive aphuculwe ngokusisiseko. Xa kuthelekiswa ne-polyurethane ecocekileyo, ukumelana nobushushu obuphezulu kunye namandla okutsalwa nawo anyukile kancinci.

I-Nano Zinc Oxide
I-Nano ZnO inamandla aphezulu oomatshini, iipropati ezilungileyo zokulwa ne-bacterial kunye ne-bacteriostatic, kunye nokukwazi okunamandla okufunxa imitha ye-infrared kunye nokukhusela okuhle kwe-UV, okwenza ukuba ifaneleke ukwenza izinto ezinemisebenzi ekhethekileyo. U-Awad et al. basebenzise indlela ye-nano positron ukufaka izizalisi ze-ZnO kwi-polyurethane. Olu phononongo lufumanise ukuba kukho intsebenziswano yonxibelelwano phakathi kwe-nanoparticles kunye ne-polyurethane. Ukunyusa umxholo we-nano ZnO ukusuka kwi-0 ukuya kwi-5% kwandisa ubushushu beglasi (Tg) ye-polyurethane, nto leyo ephucule ukuzinza kwayo kobushushu.

I-Nano Calcium Carbonate
Unxibelelwano oluqinileyo phakathi kwe-nano CaCO3 kunye ne-matrix luphucula kakhulu amandla okutsalwa kwezinto ze-polyurethane. UGao nabanye baqale baguqula i-nano-CaCO3 nge-oleic acid, baza balungisa i-polyurethane/CaCO3 ngokusebenzisa i-polymerization ye-in-situ. Uvavanyo lwe-Infrared (FT-IR) lubonise ukuba ii-nanoparticles zazisasazeke ngokulinganayo kwi-matrix. Ngokweemvavanyo zokusebenza koomatshini, kwafunyaniswa ukuba i-polyurethane eguqulwe ngee-nanoparticles inamandla okutsalwa aphezulu kune-polyurethane ecocekileyo.

I-Graphene
I-Graphene (G) sisakhiwo esineengqimba ezidityaniswe yi-SP2 hybrid orbitals, esibonisa ukuhanjiswa kwe-conductivity okugqwesileyo, ukuhanjiswa kwe-thermal, kunye nozinzo. Inamandla aphezulu, ukuqina okuhle, kwaye kulula ukuyigoba. UWu et al. badibanise ii-nanocomposites ze-Ag/G/PU, kwaye ngokwanda komxholo we-Ag/G, uzinzo lobushushu kunye nokungabandakanywa kwamanzi kwezinto ezidityanisiweyo kwaqhubeka kuphucuka, kwaye ukusebenza kwee-antibacterial nako kwanda ngokufanelekileyo.

IiNanotubes zeCarbon
Ii-nanotubes zekhabhoni (ii-CNT) zii-nanomaterials zetyhubhu ezinemilinganiselo enye ezidityaniswe zii-hexagons, kwaye okwangoku zezinye zezinto ezinoluhlu olubanzi lwezicelo. Ngokusebenzisa amandla ayo aphezulu, ukuhanjiswa, kunye neepropati ze-polyurethane composite, uzinzo lobushushu, iipropati zoomatshini, kunye nokuhanjiswa kwezinto zinokuphuculwa. UWu et al. bazise ii-CNTs nge-polymerization yangaphakathi ukulawula ukukhula kunye nokwakheka kwee-particles ze-emulsion, okwenza ii-CNTs zisasazeke ngokulinganayo kwi-polyurethane matrix. Ngomxholo okhulayo we-CNTs, amandla okuxinana kwezinto ezidityanisiweyo aphuculwe kakhulu.

Inkampani yethu ibonelela ngomgangatho ophezuluI-Fumed Silica, ii-Anti-hydrolysis agents (ii-crosslinking agents, i-Carbodiimide), ii-UV absorbers, njl., nto leyo ephucula kakhulu ukusebenza kwe-polyurethane.
