Polyurethane ikoreshwa mu mazi ni ubwoko bushya bwa sisitemu ya polyurethane ikoresha amazi aho gukoresha imiti ihumanya ikirere nk'uburyo bwo gukwirakwiza. Ifite ibyiza byo kudahumanya ikirere, umutekano n'ubwirinzi, imiterere myiza ya mekanike, guhuza neza, no guhindura byoroshye.
Ariko kandi, ibikoresho bya polyurethane bifite ikibazo cyo kudahangana n’amazi neza, kudahangana n’ubushyuhe, no kudahangana n’ibintu bishongesha bitewe n’uko nta migozi ihamye ihuza ibintu.

Kubwibyo, ni ngombwa kunoza no kunoza imiterere itandukanye ya polyurethane binyuze mu gushyiraho monomer zigira akamaro nka organic fluorosilicone, epoxy resin, acrylic ester, na nanomaterials.
Muri byo, ibikoresho bya polyurethane byahinduwe na nanomaterial bishobora kunoza cyane imiterere yabyo ya mekanike, kudashira no kudashira kw'ubushyuhe. Uburyo bwo guhindura burimo uburyo bwo guhuza imashini, uburyo bwo gupomera ibintu mu buryo busanzwe, uburyo bwo kuvanga, nibindi.

Nano Silika
SiO2 ifite imiterere y’urusobe rw’ibintu bitatu, ifite umubare munini w’amatsinda ya hydroxyl akora ku buso bwayo. Ishobora kunoza imiterere y’ibice by’umusemburo nyuma yo guhuzwa na polyurethane hakoreshejwe covalent bond na van der Waals force, nko guhinduka, kudahinduka kw’ubushyuhe bwinshi n’ubukonje, kudasaza, nibindi. Guo n’abandi bakoranye na polyurethane yahinduwe nano-SiO2 bakoresheje uburyo bwa in-situ polymerization. Iyo ingano ya SiO2 yari hafi 2% (wt, igice cy’uburemere, kimwe kiri hasi), ubukana bwo gukata n’imbaraga z’igishishwa bya kole byarazamutse cyane. Ugereranyije na polyurethane yonyine, kudahinduka kw’ubushyuhe bwinshi n’imbaraga zo gukurura nabyo byariyongereyeho gato.

Okiside ya Nano Zinc
Nano ZnO ifite imbaraga nyinshi mu byuma, ifite ubushobozi bwo kurwanya bagiteri na bagiteri, ndetse ifite ubushobozi bwo kwinjiza imirasire ya infrared hamwe n’uburinzi bwiza bwa UV, bigatuma ikoreshwa mu gukora ibikoresho bifite imikorere yihariye. Awad n'abandi bakoresheje uburyo bwa nanopositron kugira ngo bashyiremo ZnO fillers muri polyurethane. Ubushakashatsi bwagaragaje ko hari imikoranire hagati y’uduce duto na polyurethane. Kongera ingano ya nano ZnO kuva kuri 0 kugeza kuri 5% byongera ubushyuhe bw’ikirahure (Tg) cya polyurethane, bituma ubushyuhe bwayo burushaho gukomera.

Karubonate ya Nano Kalisiyumu
Ikorana rikomeye hagati ya nano CaCO3 na matrix ryongera cyane imbaraga zo gukurura ibikoresho bya polyurethane. Gao n'abandi babanje guhindura nano-CaCO3 hamwe na aside oleic, hanyuma bategura polyurethane/CaCO3 binyuze muri polymerization iri muri situ. Isuzuma rya infrared (FT-IR) ryagaragaje ko uduce duto twakwirakwiriye muri matrix. Dukurikije ibizamini by'imikorere ya mekanike, byagaragaye ko polyurethane yahinduwe na nanoparticles ifite imbaraga zo gukurura kurusha polyurethane yonyine.

Graphene
Graphene (G) ni imiterere y’ibice bifatanye na orbitals za SP2 hybrid, igaragaza ubushobozi bwo gutwara neza, ubushobozi bwo gutwara ubushyuhe, no kudahungabana. Ifite imbaraga nyinshi, gukomera neza, kandi yoroshye kuyigonda. Wu n'abandi bakoze nanocomposites za Ag/G/PU, kandi uko Ag/G yiyongera, ubushobozi bwo kugumana ubushyuhe n'amazi mu bintu bivanze byakomeje gutera imbere, kandi imikorere ya antibiyotike nayo yariyongereye.

Utuyoboro twa Karuboni
Uduce twa nanotube twa karuboni (CNTs) ni utwuma duto tw’umuraba duhujwe na hexagons, kandi ubu ni kimwe mu bikoresho bifite uburyo butandukanye bwo gukoresha. Binyuze mu gukoresha imbaraga zabyo nyinshi, ubushobozi bwo gutwara ibintu, n’ubushobozi bwa polyurethane, ubushobozi bwo guhagarara neza mu bushyuhe, imiterere ya mekanike, n’ubushobozi bwo gutwara ibintu bishobora kunozwa. Wu n’abandi bashyizeho CNTs binyuze muri polymerization iri mu mwanya wayo kugira ngo bagenzure gukura no gushinga uduce twa emulsion, bituma CNTs zikwirakwira kimwe muri polyurethane matrix. Bitewe n’ubwiyongere bw’ibice bya CNTs, imbaraga zo gukurura ibintu bivanze zarushijeho kunozwa cyane.

Isosiyete yacu itanga serivisi nziza cyaneSilika ifumye, Irwanya hydrolysis (ibintu bihuza, Carbodiimide), ibikoresho bigabanya imirasire ya UVn'ibindi, binongera cyane imikorere ya polyurethane.
