I-polyurethane eqhutshwa ngamanzi uhlobo olusha lwesistimu ye-polyurethane esebenzisa amanzi esikhundleni sezinyibilikisi eziphilayo njengendlela yokuhlakaza. Inezinzuzo zokungangcolisi, ukuphepha nokuthembeka, izakhiwo ezinhle kakhulu zemishini, ukuhambisana okuhle, kanye nokuguqulwa okulula.
Kodwa-ke, izinto ze-polyurethane nazo zihlushwa ukumelana kwamanzi okungekuhle, ukumelana nokushisa, kanye nokumelana nesinyibilikisi ngenxa yokuntuleka kwezibopho eziqinile zokuxhumanisa.

Ngakho-ke, kubalulekile ukuthuthukisa nokwenza ngcono izakhiwo ezahlukene zokusetshenziswa kwe-polyurethane ngokwethula ama-monomers asebenzayo njenge-organic fluorosilicone, i-epoxy resin, i-acrylic ester, kanye nama-nanomaterials.
Phakathi kwazo, izinto ze-polyurethane eziguquliwe ze-nanomaterial zingathuthukisa kakhulu izakhiwo zazo zemishini, ukumelana nokuguguleka, kanye nokuzinza kokushisa. Izindlela zokuguqula zifaka phakathi indlela ye-intercalation composite, indlela ye-in-situ polymerization, indlela yokuxuba, njll.

I-Nano Silica
I-SiO2 inesakhiwo senethiwekhi esinezinhlangothi ezintathu, enenani elikhulu lamaqembu e-hydroxyl asebenzayo ebusweni bayo. Ingathuthukisa izakhiwo eziphelele zenhlanganisela ngemuva kokuhlanganiswa ne-polyurethane ngesibopho se-covalent kanye namandla e-van der Waals, njengokuguquguquka, ukumelana nokushisa okuphezulu nokuphansi, ukumelana nokuguga, njll. UGuo nabanye bahlanganise i-polyurethane eguquliwe ye-nano-SiO2 besebenzisa indlela ye-polymerization yangaphakathi. Lapho okuqukethwe kwe-SiO2 kwakucishe kube ngu-2% (wt, mass fraction, okufanayo ngezansi), i-shear viscosity kanye namandla e-peel e-glue athuthukisiwe ngokuyisisekelo. Uma kuqhathaniswa ne-polyurethane emsulwa, ukumelana nokushisa okuphezulu kanye namandla okudonsa nakho kukhuphuke kancane.

I-Nano Zinc Oxide
I-Nano ZnO inamandla aphezulu okusebenza, izakhiwo ezinhle zokulwa namagciwane kanye ne-bacteriostatic, kanye nekhono eliqinile lokumunca imisebe ye-infrared kanye nokuvikela okuhle kwe-UV, okwenza ifaneleke ukwenza izinto ezinemisebenzi ekhethekile. U-Awad nabanye basebenzise indlela ye-nano positron ukufaka izigcwalisi ze-ZnO ku-polyurethane. Ucwaningo luthole ukuthi kwakukhona ukuxhumana phakathi kwama-nanoparticles kanye ne-polyurethane. Ukwandisa okuqukethwe kwe-nano ZnO kusuka ku-0 kuya ku-5% kwandisa izinga lokushisa lokuguqulwa kwengilazi (Tg) ye-polyurethane, okwathuthukisa ukuzinza kwayo kokushisa.

I-Nano Calcium Carbonate
Ukusebenzisana okuqinile phakathi kwe-nano CaCO3 kanye ne-matrix kuthuthukisa kakhulu amandla okudonsa ezinto ze-polyurethane. UGao nabanye baqale baguqula i-nano-CaCO3 nge-oleic acid, base belungisa i-polyurethane/CaCO3 ngokusebenzisa i-polymerization yangaphakathi. Ukuhlolwa kwe-Infrared (FT-IR) kubonise ukuthi ama-nanoparticles ahlakazeke ngokulinganayo ku-matrix. Ngokusho kokuhlolwa kokusebenza komshini, kutholakale ukuthi i-polyurethane eguqulwe ngama-nanoparticles inamandla okudonsa aphezulu kune-polyurethane emsulwa.

I-Graphene
I-Graphene (G) iyisakhiwo esinezingqimba esihlanganiswe yi-SP2 hybrid orbitals, esibonisa ukuhanjiswa kwe-conductivity okuhle kakhulu, ukuhanjiswa kwe-thermal, kanye nokuzinza. Inamandla aphezulu, ukuqina okuhle, futhi kulula ukuyigoba. UWu nabanye bahlanganise ama-nanocomposites e-Ag/G/PU, futhi ngokwanda kokuqukethwe kwe-Ag/G, ukuzinza kwe-thermal kanye ne-hydrophobicity yezinto ezihlanganisiwe kwaqhubeka nokuthuthuka, futhi ukusebenza kwe-antibacterial nakho kwanda ngokufanele.

Ama-Nanotubes e-Carbon
Ama-carbon nanotubes (ama-CNT) angama-nanomaterial e-tubular anobukhulu obubodwa axhunywe ngama-hexagon, futhi njengamanje angenye yezinto ezinezinto eziningi ezisetshenziswayo. Ngokusebenzisa amandla ayo aphezulu, ukuhanjiswa kwamandla, kanye nezakhiwo ze-polyurethane composite, ukuzinza kokushisa, izakhiwo zemishini, kanye nokuhanjiswa kwamandla kwezinto kungathuthukiswa. UWu nabanye bethule ama-CNT ngokusebenzisa i-polymerization yangaphakathi ukuze kulawulwe ukukhula nokwakheka kwezinhlayiya ze-emulsion, okuvumela ama-CNT ukuthi ahlakazeke ngokulinganayo ku-polyurethane matrix. Ngokuqukethwe okwandayo kwama-CNT, amandla okudonsa kwezinto ezihlanganisiwe athuthukisiwe kakhulu.

Inkampani yethu inikeza ikhwalithi ephezuluI-Fumed Silica, Ama-Anti-hydrolysis Agents (ama-crosslinking agents, i-Carbodiimide), ama-UV absorbers, njll., okuthuthukisa kakhulu ukusebenza kwe-polyurethane.
