Dị ka "onye ndu arụmọrụ" n'etiti mkpuchi mmiri dị ugbu a, akụkụ abụọ nke polyurethane (WB 2K-PUR) na-eche ihe ịma aka bụ isi ihu: ịhazi nha na arụmọrụ nke usoro polyol. N'afọ a, ndị otu nyocha mere nyocha nke omimi n'ime mmetụta synergistic nke polyether polyol (PTMEG) na polyester polyol (P1012).
Na omenala, polyester polyol enhances mkpuchi ike na njupụta n'ihi nnukwu intermolecular hydrogen agbụ, ma ngafe mgbakwunye na-ebelata mmiri iguzogide n'ihi ike hydrophilicity nke ester otu.

"Ịjikọta nkwụsi ike na mgbanwe": Mgbanwe kemịkalụ na-emepe oke ọrụ ọhụrụ
Ọ bụ ezie na njikarịcha nha anya bụ “mgbanwe dị mma,” mgbanwe kemịkalụ na-anọchi anya “mmali qualitative” maka polyurethane sitere na mmiri. Ụzọ mgbanwe abụọ pụtara n'afọ a:
Ụzọ 1: Mmelite mmekọrịta na Polysiloxane na Terpene Derivatives
Nchikota nke polysiloxane ike dị ala (PMMS) na ihe nrụpụta hydrophobic terpene na-enye WPU nwere njirimara abụọ nke "superhydrophobicity + nnukwu siri ike." Ndị na-eme nchọpụta kwadebere polysiloxane hydroxyl-treminated (PMMS) site na iji 3-mercaptopropylmethyldimethoxysilane na octamethylcyclotetrasiloxane, wee nyadokwa isobornyl acrylate (nke sitere na biomass-enweta camphene) n'elu PMMS n'akụkụ ụdọ site na UV-initiated thiol-Polycexane pịa mmeghachi omume nke PMMS.
WPU emezigharịrị gosipụtara mmụba dị ịrịba ama: akụkụ kọntaktị mmiri static siri na 70.7° ruo 101.2° (na-eru nso na akwukwo lotus dị ka superhydrophobicity), nnabata mmiri gbadara site na 16.0% gaa na 6.9%, na ike ike gbagoro site na 4.70MPa ruo 8.82MPa n'ihi nhazi ahụ siri ike. Nyocha Thermogravimetric gosikwara nkwụsi ike nke okpomọkụ. Nkà na ụzụ a na-enye ihe ngwọta "mgbochi mmebi + ihu igwe na-eguzogide" agbakwunyere maka akụkụ okporo ụzọ ụgbọ okporo ígwè dị ka akụkụ elu ụlọ na uwe mwụda n'akụkụ.
Ụzọ 2: Polyimine Crosslinking na-eme ka nkà na ụzụ "Ịgwọ onwe"
Ngwọta onwe onye apụtala dị ka teknụzụ na-ewu ewu na mkpuchi, nyocha nke afọ a jikọtara ya na arụ ọrụ WPU iji nweta ọganihu abụọ na "arụmọrụ dị elu + ike ịgwọ onwe ya." Crosslinked WPU kwadebere na polybutylene glycol (PTMG), isophorone diisocyanate (IPDI), na polyimine (PEI) dị ka crosslinker gosipụtara nnukwu ihe eji arụ ọrụ: ike ike nke 17.12MPa na elongation na nkwụsị nke 512.25% (nso mgbanwe rọba).
N'ụzọ dị oke mkpa, ọ na-enweta ọgwụgwọ onwe ya zuru oke na awa 24 na 30 Celsius - na-agbake na ike 3.26MPa na 450.94% elongation mgbe emezichara. Nke a na-eme ka ọ dabara nke ọma maka akụkụ ndị na-akpachapụ anya dị ka ihe mkpuchi ụgbọ ala na ime ụgbọ okporo ígwè, na-ebelata ọnụ ahịa mmezi.
"Nchịkwa ọgụgụ isi nke Nanoscale": "Mgbanwe dị n'elu" maka mkpuchi mkpuchi mgbochi.
Mgbochi graffiti na nhicha dị mfe bụ isi ihe achọrọ maka mkpuchi dị elu. N'afọ a, mkpuchi na-eguzogide ọgwụ (NP-GLIDE) dabere na "mmiri dị ka PDMS nanopools" dọtara mmasị. Ụkpụrụ ya bụ isi na-agụnye ịdo ụdọ polydimethylsiloxane (PDMS) n'akụkụ azụ polyol nke na-ekesa mmiri site na graft copolymer polyol-g-PDMS, na-akpụ "nanopools" dị obere karịa 30nm na dayameta.
Ọganihu PDMS na nanopools ndị a na-enye mkpuchi ahụ ihu "mmiri dị ka" - ihe niile na-anwale mmiri mmiri nwere esemokwu elu n'elu 23mN / m (dịka, kọfị, mmanụ mmanụ) na-apụ na-ahapụghị akara. N'agbanyeghị ike nke 3H (nke dị nso na iko nkịtị), mkpuchi ahụ na-ejigide arụmọrụ mgbochi dị mma.
Na mgbakwunye, a tụrụ aro “ihe mgbochi anụ ahụ + nhicha dị nro” mgbochi graffiti: iwebata IPDI trimer n'ime polyisocyanate dabere na HDT iji kwalite njupụta ihe nkiri ma gbochie ntinye akwụkwọ graffiti, ebe ị na-achịkwa mbugharị nke akụkụ silicone/fluorine iji hụ na ike elu dị ala na-adịte aka. Ejikọtara ya na DMA (Dynamic Mechanical Analysis) maka njikwa njupụta crosslink ziri ezi na XPS (X-ray Photoelectron Spectroscopy) maka njirimara migration interface, nkà na ụzụ a dị njikere maka mmepụta ihe na-atụ anya na ọ ga-abụ akara ọhụrụ maka mgbochi mmebi na agba ụgbọ ala na ihe mkpuchi ngwaahịa 3C.
