Plasma mwachindunji polymerization ndondomeko
Njira ya polymerization ya Plasma ndiyosavuta kwa zida zonse zamkati zama electrode polymerization ndi zida zakunja zama electrode polymerization, koma kusankha magawo ndikofunikira kwambiri mu polymerization ya Plasma, chifukwa magawo amakhudza kwambiri kapangidwe kake ndi kachitidwe ka mafilimu a polima panthawi ya polymerization ya Plasma.
Masitepe opangira ma polymerization a plasma ndi awa:
(1) Kupukuta
The maziko zingalowe wa polymerization pansi zingalowe mikhalidwe ayenera kupopa kwa 1.3 × 10-1Pa.Pamachitidwe a polymerization omwe amafunikira zofunikira zapadera zowongolera zomwe zili ndi mpweya kapena nayitrogeni, kufunikira kwa vacuum yakumbuyo ndikokwera kwambiri.
(2) Limbikitsani zochita monomer kapena mpweya wosakaniza wa chonyamulira mpweya ndi monoma
Digiri ya vacuum ndi 13-130Pa.Pa Plasma polymerization yomwe ikufuna ntchito, njira yoyenera yoyendetsera kayendetsedwe kake ndi kuchuluka kwamayendedwe azisankhidwa, nthawi zambiri 10.100mL/min.Mu plasma, mamolekyu a monomer amapangidwa ndi ionized ndipo amasiyanitsidwa ndi bombardment ya tinthu tating'onoting'ono, zomwe zimapangitsa kuti tinthu tating'onoting'ono monga ma ion ndi majini yogwira.The yogwira particles adamulowetsa ndi plasma akhoza kukumana Plasma polymerization pa mawonekedwe a gasi gawo ndi olimba gawo.The monomer ndiye gwero la kalambulabwalo kwa Plasma polymerization, ndi athandizira reaction gasi ndi monoma adzakhala ndi chiyero.
(3) Kusankhidwa kwa magetsi olimbikitsa
Madzi a m'magazi amatha kupangidwa pogwiritsa ntchito magetsi a DC, high-frequency, RF, kapena microwave kuti apereke chilengedwe cha plasma polima.Kusankhidwa kwa magetsi kumatsimikiziridwa malinga ndi zofunikira za mapangidwe ndi ntchito ya polima.
(4) Kusankha njira yotulutsira
Pazofunikira za polima, plasma polymerization imatha kusankha mitundu iwiri yotulutsa: kutulutsa kosalekeza kapena kutulutsa kugunda.
(5) Kusankhidwa kwa magawo otulutsa
Pochita ma polymerization a Plasma, magawo otulutsa amayenera kuganiziridwa kuchokera ku magawo a plasma, katundu wa polima ndi zofunikira zamapangidwe.Kukula kwa mphamvu yogwiritsidwa ntchito pa polymerization kumatsimikiziridwa ndi kuchuluka kwa chipinda chopumulira, kukula kwa elekitirodi, kuthamanga kwa monomer ndi kapangidwe kake, kuchuluka kwa polymerization, ndi kapangidwe ka polima ndi magwiridwe antchito.Mwachitsanzo, ngati kuchuluka kwa chipindacho ndi 1L ndipo RF Plasma polymerization imatengedwa, mphamvu yotulutsa idzakhala mu 10 ~ 30W.Pazifukwa zotere, plasma yopangidwa imatha kuphatikizika kuti ipange filimu yopyapyala pamwamba pa chogwiriracho.Kukula kwa filimu ya Plasma polymerization kumasiyanasiyana ndi magetsi, mtundu wa monomer ndi kuchuluka kwa kayendedwe kake, ndi momwe zimakhalira.Nthawi zambiri, kukula kwake ndi 100nm/min~1um/min.
(6) Muyezo wa Parameter mu Plasma polymerization
Magawo a plasma ndi magawo omwe amayezedwa mu Plasma polymerization ndi awa: voteji yotulutsa, kutulutsa kwapano, kutulutsa pafupipafupi, kutentha kwa Electron, kachulukidwe, mtundu wamagulu ndi kukhazikika, ndi zina zambiri.
