iindaba

I-Polyethyleneimine (PEI) Cas 9002-98-6ineentlobo ngeentlobo zezicelo kwishishini lempahla yelaphu kwaye sisixhobo esibalulekileyo sepolymer esisebenzayo. Ixabiso layo eliphambili likwiindawo ezininzi ezitshajiweyo kakuhle kunye nokusebenza kwayo okuphezulu, okuvumela ukuba idibane neefayibha ezitshajiweyo kakubi, iidayi, kunye nee-reagents ezahlukeneyo ezisebenzayo, ngaloo ndlela inika impahla yelaphu iipropati ezintsha okanye eziphuculweyo.

Ezi zilandelayo zezona zicelo ziphambili kunye namaxabisoI-PEIkwishishini lempahla:

Ⅰ. Ukudaya nokuPrinta: Ukuphucula ukusebenza kombala kunye nobuhlobo nokusingqongileyo

I-PEIiphucula kakhulu imiphumo yokudaya nokuprinta kwempahla ngokubopha izinto zayo zedayi ye-cationic kunye ne-anionic, ngelixa inciphisa ungcoliseko.

1. Ubunzulu Bokudaya Obunyukileyo (Ixabiso le-K/S) kunye Nokungaguquguquki Kombala:

Amalaphu aphathwe nge-PEI afana nomqhaphu noboya abonakalisa ukufunxwa kwedayi okuphucukileyo kakhulu, nto leyo ebangela imibala enzulu neqaqambileyo. Kwangaxeshanye, iimpawu ezahlukeneyo zokuqina kombala zamalaphu adayiweyo naprintiweyo (ezifana nokumelana nokuhlanjwa kunye nokumelana nokukhuhla) ziphuculwe kakhulu. Umzekelo, uphando lwango-2025 lubonise ukunyuka okukhulu kwepesenti kubukhali bombala (ixabiso le-K/S) lamalaphu aphathwe nge-PEI.

2. Ukufezekisa ukuPrintwa kwe-Inkjet ngaphambi konyango/engahlanjwanga:

Ukusebenzisa i-hyperbranchedi-polyethyleneimine (PEI)Ii-inki zedayi eziguqukayo (ezifana ne-inki ye-PEI-R218), ukuprintwa kwe-inkjet kunokwenziwa ngokuthe ngqo kwilaphu elinganyangwanga, oku kufikelela kwizinga lokufakwa kwedayi elingaphezulu kwe-98.7%. Oku kuphelisa iinkqubo zemveli zokulinganisa ubungakanani bangaphambi kokuprinta kunye neenkqubo zokuhlamba emva kokuprinta, okunciphisa kakhulu ukusetyenziswa kweekhemikhali, amanzi kunye namandla.

3. Ukukhuthaza ukusetyenziswa kweedayi zendalo:

Amalaphu esilika aguqulwe yi-PEI anokuphucula ngempumelelo izinga lokudaya kunye nefuthe lokudaya kweedayi zendalo ezifana ne-curcumin, nto leyo ekhuthaza iinkqubo zokudaya ezinobuhlobo nokusingqongileyo.

II. Ukugqiba umsebenzi: Ukunika amalaphu “amandla amakhulu”

I-PEIsisithako esibalulekileyo ekuvelisweni kweempahla ezisebenzayo, ingakumbi xa zingasebenzi kakuhle.

1.Ukusebenza kakuhle kakhulu kokukhanya kwelangatye

Ityebile kwi-nitrogen,I-PEIisetyenziswa rhoqo njengomthombo wekhabhoni okanye igesi kwiinkqubo zokurhoxisa umlilo ezingaphakathi, isebenza ngokubambisana nezinye izinto zokurhoxisa umlilo ezine-phosphorus kunye ne-silicon.

Amalaphu ekotoni: Xa edityaniswe nezinto ezithintela ilangatye ezisekelwe kwibhayoloji ezifana ne-phytic acid (PA), kunye nokutshintshiselana kwee-ion okanye ukufakelwa ngee-agents ezidibanisayo, izinto ezithintela ilangatye ezisebenza kakuhle kakhulu zinokwakhiwa.

2. Amalaphu e-viscose

I-Phosphate-esterified PEI, njenge-flame retardant, inokunyusa i-limiting oxygen index (LOI) yamalaphu ukuya kwi-28.9%, ikwazi ukuzicima ngokwayo xa isuswa ilangatye.

3. I-PA56, i-PAN, kunye nezinye iifayibha zokwenziwa

Ngokusebenzisa iteknoloji yokuzihlanganisa okanye yokuzihlanganisa ngokwamaleko, iinethiwekhi ezidityanisiweyo zinokwenziwa, zifezekise ukulibaziseka komlilo okuhlala ixesha elide. Umzekelo, ilaphu le-PAN eliphathwe nge-PA/PEI/APTES libonisa ukwanda kwe-oxygen index (LOI) ukusuka kwi-17.4% ukuya kwi-27.5%, kwaye libonisa iimpawu ezintle zokuthintela umsi.

4. Iimpawu ze-antibacterial kunye ne-antioxidant

I-PEI ngokwayo kunye neekhompawundi zayo zokudibanisa isinyithi (ezifana ne-PEI-Cu) zineempawu zokulwa nentsholongwane. Amalaphu ekotoni aphathwe nge-PEI abonise zombini iipropati ze-antibacterial ezingama-83.33% kunye ne-antioxidant ezingama-74.2% kwizicelo ze-triboelectric nanogenerator (T-TENG).

5. Ukuqhuba Okuphuculweyo kunye neempawu ezichasene nokungashukumi:

Ukukhusela i-Electromagnetic: Intambo ye-polyamide (PA) eguqulwe yi-PEI iyomeleza kakhulu ukunamathela kwengubo ye-graphene oxide (GO). Intambo eqhubayo ephumayo igcina ukukhupha okuphezulu kwe-4.7 × 10³ S/m emva kokugoba kwe-10,000, ifikelela ekusebenzeni kokukhusela i-electromagnetic ukuya kuthi ga kwi-66.7 dB.

6. Iimpawu zokungashukumi

I-PEIkuphucula ukunamathela kwamanzi kwilaphu, kunciphisa ukwakheka kombane ongashukumiyo.

7. Uboya obuchasene nokugquma

Inkqubo eqhubekayo yokugqiba i-anti-felting esebenzisa i-potassium persulfate (PMS)-PEI kwinkqubo enamanyathelo amabini yinkqubo engena-chlorine kwaye inobuhlobo nokusingqongileyo.

8. Ukuphucula Ukufuma Nokunamathela Kwamanzi

I-PEIunyango luphucula kakhulu ukufuma kweefayibha ezingafuni manzi ezifana noboya, kwaye i-PEI enobunzima obuphezulu ibonisa iziphumo ezingcono.

III. Ukuguqulwa komphezulu: Ukwakha "ibhulorho" esebenzayo

I-PEIingasetyenziselwa "njengomaleko wokudibanisa" okanye "njengearhente yokuncamathelisa" yokuguqula ifayibha enzulu.

1. Ukuphucula Amandla Okugquma

Njengengubo esisiseko, i-PEI inokuphucula kakhulu amandla okulayisha kunye nokubopha kwezinto ezisebenzayo (ezifana ne-MXene (Ti₃C₂Tₓ) kunye ne-graphene oxide (GO)) kumphezulu wefayibha.

2. Ukulungiswa kweeComposites ezisebenzayo

Ingasetyenziselwa ukulungiselela izinto ezidityanisiweyo ezifana nee-aerogels ze-PEI@PLA kwizicelo ezifana nokufunxwa kwedayi.

3. I-Catalytic Chemical Plating

Njenge-agent ye-cationizing, ingasetyenziselwa ukunyanga imicu yekotoni, ivumela i-catalytic chemical plating ye-copper sulfide (CuS) kumphezulu wayo, ngaloo ndlela ifezekisa ukuhanjiswa kwamandla.

Ⅳ. Isishwankathelo

I-Polyethyleneimine (PEI)Ixabiseke kakhulu kushishino lwempahla yelaphu kuzo zonke izigaba, ukusuka ekudayweni nasekugqityweni kokusebenza kakuhle ukuya ekulungisweni kwezinto ezidityanisiweyo ezisebenza kakuhle. Ayisiyo "inkxaso" yokuphucula ukusebenza kakuhle kunye nobuhlobo nokusingqongileyo kwempahla yemveli (umqhaphu, uboya, isilika), kodwa ikwayeyona nto iphambili ekuphuhliseni impahla yelaphu yanamhlanje ekrelekrele, ekhuselayo, nesebenza kakuhle.

Kufuneka kuqatshelwe ukuba isiphumo sokusetyenziswa kweI-PEIinxulumene ngokusondeleyo neeparameter zayo zesakhiwo ezifana nobunzima beemolekyuli kunye nobungakanani bokuhluma. Kwizicelo ezisebenzayo, kuyimfuneko ukuyikhetha nokuyiphucula ngokwenkqubo ethile.
