izindaba

I-Polyethyleneimine (PEI) Cas 9002-98-6inezinhlobo eziningi zezicelo embonini yezindwangu futhi iyinto ebalulekile ye-polymer esebenzayo. Inani layo eliyinhloko lisezinhlakeni zayo eziningi ezishajelwe kahle kanye nokusebenza okuphezulu, okuvumela ukuthi ihlangane nemicu eshajelwe kabi, amadayi, kanye nama-reagent ahlukahlukene asebenzayo, ngaleyo ndlela inikeze izindwangu izakhiwo ezintsha noma ezithuthukisiwe.

Okulandelayo yizinhlelo zokusebenza eziyinhloko kanye namanani e-I-PEIembonini yezindwangu:

Ⅰ. Ukudaya Nokuphrinta: Ukuthuthukisa Ukusebenza Kombala Nobungani Bemvelo

I-PEIithuthukisa kakhulu imiphumela yokudaya nokuphrinta kwezindwangu ngokubopha izingxenye zayo zedayi ye-cationic ne-anionic, ngenkathi inciphisa ukungcola.

1. Ukwanda Kokujula Kokudaya (Inani le-K/S) kanye Nokuqina Kombala:

Izindwangu eziphathwe nge-PEI ezifana nokotini noboya zibonisa ukumuncwa kodayi okuthuthukisiwe kakhulu, okuholela emibala ejulile negqamile. Ngesikhathi esifanayo, izici ezahlukahlukene zokuqina kombala zezindwangu ezidaywe neziprintiwe (njengokumelana nokuwasha kanye nokumelana nokuhlikihla) zithuthukiswa kakhulu. Isibonelo, ucwaningo lwango-2025 lubonise ukwanda okukhulu kwamaphesenti ekuqineni kombala (inani le-K/S) wezindwangu eziphathwe nge-PEI.

2. Ukufeza Ukuphrinta Kwe-Inkjet Ngaphambi Kokwelashwa Okungahlanzwa/Okungagezwa:

Ukusebenzisa i-hyperbranchedi-polyethyleneimine (PEI)Uyinki wedayi oguquguqukayo oguquliwe (njengoyinki we-PEI-R218), ukuphrinta kwe-inkjet kungenziwa ngqo ezindwangu ezingakalungiswa, kufinyelele izinga lokufakwa kwedayi elingaphezu kuka-98.7%. Lokhu kuqeda izinqubo zokwehlukanisa usayizi wangaphambi kokuphrinta kanye nezinqubo zokuwasha ngemuva kokuphrinta zendabuko, kunciphisa kakhulu ukusetshenziswa kwamakhemikhali, amanzi, kanye namandla.

3. Ukukhuthaza ukusetshenziswa kwamadayi emvelo:

Izindwangu zikasilika eziguqulwe yi-PEI zingathuthukisa ngempumelelo izinga lokudaya kanye nomphumela wokudaya kwamadayi emvelo afana ne-curcumin, okukhuthaza izinqubo zokudaya ezinobungani nemvelo.

II. Ukuqedela umsebenzi: Ukunikeza izindwangu “amandla amakhulu”

I-PEIiyisengezo esibalulekile ekukhiqizweni kwezindwangu ezisebenzayo, ikakhulukazi ephumelela kakhulu ekubambeni ilangabi.

1.Ukuqina komlilo okusebenzayo okuphezulu

Icebile nge-nitrogen,I-PEIivame ukusetshenziswa njengomthombo wekhabhoni noma igesi ezinhlelweni zokuvimbela umlilo ezingaphakathi, isebenza ngokubambisana nezinye izinto zokuvimbela umlilo eziqukethe i-phosphorus ne-silicon.

Izindwangu zikakotini: Uma zihlanganiswa nezinto ezigcina ilangabi ezisekelwe ku-bio ezifana ne-phytic acid (PA), kanye nangokushintshaniswa kwama-ion noma ukufakelwa ngama-agent okuxhumanisa, kungakhiwa izembozo ezigcina ilangabi ezisebenza kahle kakhulu.

2. Izindwangu ze-viscose

I-PEI ene-phosphate-esterified, njenge-flame retardant, ingandisa i-limiting oxygen index (LOI) yezindwangu ibe ngu-28.9%, ikwazi ukuzicisha ngokwayo lapho isuswa ilangabi.

3. I-PA56, i-PAN, kanye neminye imicu yokwenziwa

Ngokusebenzisa ubuchwepheshe bokuxhunyelelwa noma bokuzihlanganisa ngezingqimba, amanethiwekhi axhumene angakhiwa, kufezwe ukuqina komlilo okuhlala isikhathi eside. Isibonelo, indwangu ye-PAN ephathwe nge-PA/PEI/APTES ikhombisa ukwanda kwe-oxygen index (LOI) ekhawulelwe kusuka ku-17.4% kuya ku-27.5%, futhi ikhombisa izakhiwo ezinhle kakhulu zokucindezela intuthu.

4. Izakhiwo zokulwa namagciwane kanye ne-antioxidant

I-PEI ngokwayo kanye nama-compound ayo okuhlanganisa insimbi (njenge-PEI-Cu) anezakhiwo zokulwa namagciwane. Izindwangu zikakotini eziphathwe nge-PEI zibonise kokubili izinga lokulwa namagciwane elingu-83.33% kanye nezakhiwo ze-antioxidant ezingu-74.2% ekusetshenzisweni kwe-triboelectric nanogenerator (T-TENG).

5. Ukuthuthukiswa Kokusebenza kanye Nezakhiwo Ezingashintshi:

Ukuvikela Nge-Electromagnetic: Intambo ye-polyamide (PA) eguquliwe yi-PEI iqinisa kakhulu ukunamathela kwengubo ye-graphene oxide (GO). Intambo eqhubayo ephumelayo igcina ukudlulisa okuphezulu okungu-4.7 × 10³ S/m ngemva kokugoba okungu-10,000, okufinyelela ukusebenza kahle kokuvikela nge-electromagnetic okufika ku-66.7 dB.

6. Izakhiwo Ezingashintshi

I-PEIkuthuthukisa ukunamathela kwamanzi kwezindwangu, kunciphisa ukwakheka kukagesi ongashintshi.

7. Uboya obulwa nokuqothula

Inqubo eqhubekayo yokuqeda ukuqeda i-anti-felting esebenzisa i-potassium persulfate (PMS)-PEI enkambisweni yezinyathelo ezimbili iyinqubo engena-chlorine futhi enobungani nemvelo.

8. Ukumanzi Okuthuthukisiwe kanye Nokunamathela Kwamanzi

I-PEIUkwelashwa kuthuthukisa kakhulu ukumanziswa kwemicu engabangeli ukungezwani kwamanzi njengoboya, kanti i-PEI enesisindo sama-molecule ephezulu ikhombisa imiphumela engcono.

III. Ukuguqulwa kwendawo: Ukwakha “ibhuloho” elisebenzayo

I-PEIingasetshenziswa “njengesendlalelo sokubopha” noma “njenge-anchoring agent” yokuguqulwa kwefayibha ejulile.

1. Ukuthuthukisa Amandla Okumboza

Njengesembozo esiyisisekelo, i-PEI ingathuthukisa kakhulu ukulayisha kanye namandla okubopha kwezinto ezisebenzayo (njenge-MXene (Ti₃C₂Tₓ) kanye ne-graphene oxide (GO)) ebusweni befayibha.

2. Ukulungiswa Kwezinhlanganisela Ezisebenzayo

Ingasetshenziswa ukulungiselela izinhlanganisela ezifana nama-aerogel e-PEI@PLA ukuze kusetshenziswe njengokufakwa kwedayi.

3. Ukufakwa Kwamakhemikhali Okubangela Ukuvuvukala

Njenge-ejenti yokuhlanganisa, ingasetshenziswa ukwelapha imicu kakotini, okwenza kube lula ukuthi i-copper sulfide (CuS) ifake i-catalytic chemical plating ebusweni bayo, ngaleyo ndlela ifinyelele ekuqhutshweni kwayo.

Ⅳ. Isifinyezo

I-Polyethyleneimine (PEI)Iwusizo embonini yezindwangu kuzo zonke izigaba, kusukela ekudayini nasekuqedeni okusebenzayo kuya ekulungiseleleni izinhlanganisela ezisebenza kahle kakhulu. Akuyona nje "i-booster" yokuthuthukisa ukusebenza kanye nobungane bemvelo bezindwangu zendabuko (ukotini, uboya, usilika), kodwa futhi iyinto ebalulekile yokuthuthukisa izindwangu zesimanje ezihlakaniphile, ezivikelayo, nezisebenza kahle kakhulu.

Kufanele kuqashelwe ukuthi umphumela wokusetshenziswa kweI-PEIihlobene eduze nemingcele yayo yesakhiwo njengesisindo sama-molecule kanye nezinga lokukhula kwamagatsha. Ekusetshenzisweni okungokoqobo, kuyadingeka ukuyikhetha nokuyilungiselela ngokwenqubo ethile.
