Inkqubo yokwenza i-Plasma direct polymerization

Inkqubo ye-Plasma polymerization ilula kakhulu kwizixhobo ze-electrode polymerization zangaphakathi kunye nezixhobo ze-electrode polymerization zangaphandle, kodwa ukukhethwa kweeparameter kubaluleke ngakumbi kwi-Plasma polymerization, kuba iiparameter zinempembelelo enkulu kwisakhiwo kunye nokusebenza kweefilimu ze-polymer ngexesha le-Plasma polymerization.

Amanyathelo okusebenza kwe-polymerization ye-plasma ngqo ngala alandelayo:

(1) Ukucoca ngomatshini wokucoca inkunkuma

I-vacuum yangasemva ye-polymerization phantsi kweemeko ze-vacuum kufuneka ipompelwe kwi-1.3 × 10-1Pa. Kwiimpendulo ze-polymerization ezifuna iimfuno ezikhethekileyo zokulawula umxholo we-oksijini okanye we-nitrogen, imfuneko ye-vacuum yangasemva iphezulu nangakumbi.

(2) I-monomer ye-Charge reaction okanye igesi exutyiweyo yegesi ethwala kunye ne-monomer

Iqondo le-vacuum yi-13-130Pa. Kwi-Plasma polymerization efuna umsebenzi, kufuneka kukhethwe indlela efanelekileyo yokulawula ukuhamba kwamanzi kunye nesantya sokuhamba kwamanzi, ngokubanzi yi-10.100mL/min. Kwi-plasma, iimolekyuli ze-monomer ziyahlulwahlulwa kwaye zahlulwe ngokuqhushumba kwee-particles ezinamandla, nto leyo ebangela ii-particles ezisebenzayo ezifana nee-ions kunye nee-genes ezisebenzayo. Ii-particles ezisebenzayo ezivuselelwa yi-plasma zinokudlula kwi-Plasma polymerization kwindawo ephakathi kwe-gas phase kunye ne-solid phase. I-monomer ngumthombo we-precursor ye-Plasma polymerization, kwaye i-input reaction gas kunye ne-monomer kufuneka zibe nobunyulu obuthile.

(3) Ukukhethwa kombane ovuselelayo

I-plasma inokwenziwa kusetyenziswa imithombo yamandla ye-DC, i-high-frequency, i-RF, okanye i-microwave ukubonelela ngendawo ye-plasma yokwenza i-polymerization. Ukukhethwa kombane kugqitywa ngokusekwe kwiimfuno zesakhiwo kunye nokusebenza kwe-polymer.

(4) Ukukhetha indlela yokukhupha

Kwiimfuno zepolymer, i-Plasma polymerization inokukhetha iindlela ezimbini zokukhupha: ukukhupha okuqhubekayo okanye ukukhupha nge-pulse.

(5) Ukukhethwa kweeparamitha zokukhupha

Xa kuqhutywa i-Plasma polymerization, iiparameter zokukhupha kufuneka ziqwalaselwe kwiiparameter ze-plasma, iipropati ze-polymer kunye neemfuno zesakhiwo. Ubungakanani bamandla asetyenziswayo ngexesha le-polymerization bumiselwa bubungakanani begumbi le-vacuum, ubungakanani be-electrode, izinga lokuhamba kwe-monomer kunye nesakhiwo, izinga le-polymerization, kunye nesakhiwo se-polymer kunye nokusebenza. Umzekelo, ukuba umthamo wegumbi lokusabela yi-1L kwaye i-RF Plasma polymerization yamkelwe, amandla okukhupha aya kuba kuluhlu lwe-10 ~ 30W. Phantsi kweemeko ezinjalo, i-plasma eveliswayo inokuhlangana ukuze yenze ifilimu encinci kumphezulu wesixhobo somsebenzi. Izinga lokukhula kwefilimu ye-Plasma polymerization liyahluka ngombane, uhlobo lwe-monomer kunye nezinga lokuhamba, kunye neemeko zenkqubo. Ngokubanzi, izinga lokukhula yi-100nm/min~1um/min.

(6) Ukulinganiswa kweparameter kwi-Plasma polymerization

Iiparamitha zeplasma kunye neeparamitha zenkqubo eziza kulinganiswa kwiPlasma polymerization ziquka: i-discharge voltage, i-discharge current, i-discharge frequency, i-Electron temperature, i-density, i-reaction group type kunye ne-concentration, njl.njl.
