Inqubo yokwenza i-Plasma direct polymerization

Inqubo yokwenza i-Plasma polymerization ilula kakhulu kokubili imishini yokwenza i-electrode polymerization yangaphakathi kanye nemishini yokwenza i-electrode polymerization yangaphandle, kodwa ukukhetha amapharamitha kubaluleke kakhulu ku-Plasma polymerization, ngoba amapharamitha anomthelela omkhulu esakhiweni nasekusebenzeni kwamafilimu e-polymer ngesikhathi se-Plasma polymerization.

Izinyathelo zokusebenza ze-polymerization ye-plasma eqondile yilezi ezilandelayo:

(1) Ukuhlanza ngomshini wokuhlanza

I-vacuum yangemuva ye-polymerization ngaphansi kwezimo ze-vacuum kufanele ipompelwe ku-1.3×10-1Pa. Ukuze uthole i-polymerization reactions edinga izidingo ezikhethekile zokulawula okuqukethwe yi-oxygen noma i-nitrogen, isidingo se-vacuum yangemuva siphakeme nakakhulu.

(2) I-monomer yokusabela kweshaja noma igesi exubile yegesi ethwala kanye ne-monomer

Izinga le-vacuum lingu-13-130Pa. Ukuze kusetshenziswe i-Plasma polymerization, imodi yokulawula ukugeleza efanele kanye nesilinganiso sokugeleza kufanele kukhethwe, ngokuvamile u-10.100mL/min. Ku-plasma, ama-molecule e-monomer ayahlukaniswa futhi ahlukaniswe ngokuqhuma kwezinhlayiya ezinamandla, okuholela ezinhlayiyeni ezisebenzayo ezifana nama-ion kanye nezakhi zofuzo ezisebenzayo. Izinhlayiya ezisebenzayo ezisebenza nge-plasma zingadlula ku-Plasma polymerization esibonakalayo sesigaba segesi kanye nesigaba esiqinile. I-monomer ingumthombo wesandulela se-Plasma polymerization, futhi igesi yokusabela kokufaka kanye ne-monomer kufanele ibe nobumsulwa obuthile.

(3) Ukukhethwa kokunikezwa kwamandla okuvuselela

I-plasma ingakhiqizwa kusetshenziswa imithombo yamandla ye-DC, imvamisa ephezulu, i-RF, noma i-microwave ukuze kuhlinzekwe indawo ye-plasma yokwenza i-polymerization. Ukukhethwa kokunikezwa kwamandla kunqunywa ngokusekelwe ezidingweni zesakhiwo kanye nokusebenza kwe-polymer.

(4) Ukukhetha imodi yokukhipha

Ngokwezidingo ze-polymer, i-Plasma polymerization ingakhetha izindlela ezimbili zokukhipha: ukukhishwa okuqhubekayo noma ukukhishwa kwe-pulse.

(5) Ukukhethwa kwamapharamitha okukhipha

Uma kwenziwa i-Plasma polymerization, amapharamitha okukhipha kudingeka acatshangelwe kusukela kumapharamitha e-plasma, izakhiwo ze-polymer kanye nezidingo zesakhiwo. Ubukhulu bamandla asetshenziswayo ngesikhathi se-polymerization bunqunywa yivolumu yegumbi le-vacuum, usayizi we-electrode, izinga lokugeleza kwe-monomer kanye nesakhiwo, izinga le-polymerization, kanye nesakhiwo se-polymer kanye nokusebenza. Isibonelo, uma ivolumu yegumbi lokusabela ingu-1L futhi kwamukelwa i-RF Plasma polymerization, amandla okukhipha azoba sebangeni elingu-10~30W. Ngaphansi kwezimo ezinjalo, i-plasma ekhiqizwayo ingahlangana ukuze yakhe ifilimu encane ebusweni bento yokusebenza. Izinga lokukhula lefilimu ye-Plasma polymerization liyahlukahluka ngokunikezwa kwamandla, uhlobo lwe-monomer kanye nezinga lokugeleza, kanye nezimo zenqubo. Ngokuvamile, izinga lokukhula lingu-100nm/min~1um/min.

(6) Ukulinganiswa kwepharamitha ku-Plasma polymerization

Amapharamitha e-plasma kanye namapharamitha enqubo okufanele alinganiswe ku-Plasma polymerization afaka: i-voltage yokukhipha, i-discharge current, i-discharge frequency, izinga lokushisa le-Electron, ubuningi, uhlobo lweqembu lokusabela kanye nokuhlushwa, njll.
