Maitiro ePlasma direct polymerization

Maitiro ePlasma direct polymerization

Maitiro ePlasma polymerization ari nyore kune ese ari maviri emidziyo ye electrode polymerization yemukati uye emidziyo ye electrode polymerization yekunze, asi kusarudza ma parameter kwakakosha muPlasma polymerization, nekuti ma parameter ane simba guru pachimiro uye mashandiro ema polymer films panguva yePlasma polymerization.

Matanho ekushanda kwe direct plasma polymerization ndeaya anotevera:

(1) Kuchenesa nekubvisa tsvina

Vacuum yekumashure yepolymerization pasi pemamiriro evacuum inofanira kupombwa kusvika ku1.3×10-1Pa. Kune polymerization reactions inoda zvinodiwa zvakakosha zvekudzora oxygen kana nitrogen, background vacuum inodiwa zvakanyanya.

(2) Monomer yekuchinja kwechaja kana gasi rakasanganiswa regasi rinotakura nemonomer

Dhigirii re vacuum i13-130Pa. PaPlasma polymerization inoda kushanda, nzira yakakodzera yekudzora kuyerera uye mwero wekuyerera kwemvura inofanira kusarudzwa, kazhinji 10.100mL/min. MuPlasma, mamorekuru emonomer anosanganiswa uye anoparadzaniswa nekuputirwa kwezvikamu zvine simba, zvichikonzera zvikamu zvinoshanda zvakaita semaion nemajini anoshanda. Zvikamu zvinoshanda zvinogadziriswa neplasma zvinogona kupinda muPlasma polymerization panzvimbo yegasi nechikamu chakasimba. Monomer ndiyo sosi yekutanga kwePlasma polymerization, uye gasi rekupinda reaction nemonomer zvinofanira kunge zvakachena.

(3) Kusarudzwa kwesimba rekufambisa

Plasma inogona kugadzirwa uchishandisa magetsi eDC, high-frequency, RF, kana microwave kuti ipe plasma environment yepolymerization. Kusarudzwa kwesimba remagetsi kunoenderana nezvinodiwa zvechimiro uye mashandiro epolymer.

(4) Kusarudzwa kwenzira yekuburitsa

Panyaya yezvinodiwa nepolymer, Plasma polymerization inogona kusarudza nzira mbiri dzekuburitsa: kuburitsa kunoenderera mberi kana kuburitsa kwepulse.

(5) Kusarudzwa kwezviyero zvekuburitsa

Pakuita polymerization yePlasma, maparamita ekuburitsa anofanirwa kutariswa kubva pamaparamita eplasma, hunhu hwepolymer uye zvinodiwa pachimiro. Hukuru hwesimba rinoshandiswa panguva yepolymerization hunotsanangurwa nehuwandu hwekamuri re vacuum, saizi yeelectrode, mwero wekuyerera kwemonomer uye chimiro, mwero wepolymerization, uye chimiro chepolymer uye mashandiro. Semuenzaniso, kana vhoriyamu yekamuri re reaction iri 1L uye RF Plasma polymerization yagamuchirwa, simba rekuburitsa richave riri pakati pe10~30W. Mumamiriro ezvinhu akadaro, plasma inogadzirwa inogona kuungana kuti igadzire firimu rakatetepa pamusoro pechinhu chebasa. Mwero wekukura kwePlasma polymerization film unosiyana zvichienderana nemagetsi, rudzi rwemonomer uye mwero wekuyerera, uye mamiriro ekushanda. Kazhinji, mwero wekukura i100nm/min~1um/min.

(6) Kuyerwa kweparameter muPlasma polymerization

Maparamita eplasma uye maparamita eprocess anofanira kuyerwa muPlasma polymerization anosanganisira: discharge voltage, discharge current, discharge frequency, Electron temperature, density, reaction group type uye concentration, nezvimwewo.
