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 ukhetho lweparameter lubaluleke 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.I-Plasma polymerization ifuna 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 ne-ion kunye nofuzo olusebenzayo.Amasuntswana asebenzayo asebenze ngeplasma angafumana i-Plasma polymerization kwi-interface yesigaba segesi kunye nesigaba esiqinileyo.I-monomer ngumthombo we-precursor ye-Plasma polymerization, kunye negesi yokuphendula igalelo 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 ziquka: i-voltage yokukhupha, i-excharge current, i-discharge frequency, i-Electron yokushisa, ubuninzi, uhlobo lweqela lokuphendula kunye nokugxininiswa, njl.
