Inkqubo ye-Plasma ye-polymerization ngqo

Inkqubo ye-Plasma polymerization ilula kakhulu kuzo zombini izixhobo ze-polymerization yangaphakathi ye-electrode kunye nezixhobo zangaphandle ze-polymerization ye-electrode, kodwa ukukhethwa kweparameter kubaluleke kakhulu kwi-Plasma polymerization, kuba iiparitha zinempembelelo enkulu kwisakhiwo kunye nokusebenza kweefilimu zepolymer ngexesha le-Plasma polymerization.

Amanyathelo okusebenza kwi-polymerization yeplasma ethe ngqo ngala alandelayo:

(1) Ukucoca

I-vacuum yangasemva ye-polymerization phantsi kweemeko ze-vacuum kufuneka ifakwe kwi-1.3 × 10-1Pa. Kwiimpendulo zepolymerization ezifuna iimfuno ezikhethekileyo zokulawula ioksijini okanye umxholo wenitrogen, imfuno yokucoca yangasemva iphezulu nangakumbi.

(2) Intlawulo yokuphendula i-monomer okanye igesi edibeneyo yegesi ye-carrier kunye ne-monomer

Idigri yevacuum yi-13-130Pa. Kwi-Plasma polymerization edinga umsebenzi, indlela efanelekileyo yokulawula ukuhamba kunye nesantya sokuhamba kuya kukhethwa, ngokubanzi i-10.100mL / min. Kwiplasma, iimolekyuli ze-monomer zi-ionized kwaye zahlulwa ngokuqhushumba kwamasuntswana anamandla, okukhokelela kumasuntswana asebenzayo afana neeyoni kunye nofuzo olusebenzayo. Amasuntswana asebenzayo avulwe yiplasma anokungena kwiPlasma polymerization kwi-interface yesigaba segesi kunye nesigaba esiqinileyo. I-monomer ngumthombo we-precursor ye-Plasma polymerization, kunye negesi yokusabela kwegalelo kunye ne-monomer iya kuba nobunyulu obuthile.

(3) Ukukhethwa konikezelo lwamandla okuvuselelayo

I-Plasma inokuveliswa kusetyenziswa i-DC, i-high-frequency, i-RF, okanye imithombo yamandla ye-microwave ukubonelela ngemekobume ye-plasma ye-polymerization. Ukukhethwa kokunikezelwa kwamandla kunqunywe ngokusekelwe kwiimfuno zesakhiwo kunye nokusebenza kwepolymer.

(4) Ukukhethwa kwendlela yokukhupha

Kwiimfuno zepolymer, i-Plasma polymerization ingakhetha iindlela ezimbini zokukhupha: ukukhutshwa okuqhubekayo okanye ukukhutshwa kwe-pulse.

(5) Ukukhethwa kweeparamitha zokukhupha

Xa uqhuba i-Plasma polymerization, iiparamitha zokukhupha kufuneka ziqwalaselwe kwiiparamitha zeplasma, iipropati zepolymer kunye neemfuno zesakhiwo. Ubungakanani bamandla asetyenzisiweyo ngexesha le-polymerization lichongwa ngumthamo wegumbi le-vacuum, ubungakanani be-electrode, izinga lokuhamba kwe-monomer kunye nesakhiwo, izinga le-polymerization, kunye nesakhiwo se-polymer kunye nokusebenza. Ngokomzekelo, ukuba umthamo wegumbi lokuphendula ngu-1L kunye ne-RF Plasma polymerization yamkelwa, amandla okukhutshwa aya kuba kuluhlu lwe-10 ~ 30W. Phantsi kweemeko ezinjalo, iplasma eyenziweyo inokudityaniswa yenze ifilimu ebhityileyo kumphezulu womsebenzi. Izinga lokukhula kwefilimu ye-Plasma polymerization iyahluka ngokubonelelwa kwamandla, uhlobo lwe-monomer kunye nesantya sokuhamba, kunye neemeko zenkqubo. Ngokuqhelekileyo, izinga lokukhula yi-100nm/min~1um/min.

(6) Umlinganiselo weParameter kwi-Plasma polymerization

Iiparamitha zeplasma kunye neeparitha zenkqubo eziza kulinganiswa kwi-polymerization ye-Plasma zibandakanya: i-voltage yokukhupha, i-excharge current, i-discharge frequency, i-Electron yokushisa, ubuninzi, uhlobo lweqela lokuphendula kunye nokugxila, njl.
