Plasma yakananga polymerization maitiro

Maitiro ePlasma polymerization ari nyore kune ese emukati emagetsi epolymerization midziyo uye ekunze electrode polymerization midziyo, asi kusarudzwa kweparameter kunonyanya kukosha muPlasma polymerization, nekuti maparamendi ane simba guru pachimiro nekuita kwemafirimu epolymer panguva yePlasma polymerization.

Matanho ekushanda ekunangisa plasma polymerization ndeaya anotevera:

(1) Vacuuming

Iyo yekumashure vacuum ye polymerization pasi pevacuum mamiriro inofanira kupomba kune 1.3 × 10-1Pa.Kune mapolymerization maitiro ayo anoda zvakakosha zvinodiwa pakudzora okisijeni kana nitrogen yemukati, iyo yekumashure vacuum inodiwa yakatokwira.

(2) Charge reaction monomer kana gasi rakasanganiswa rekutakura gasi uye monomer

Iyo vacuum degree ndeye 13-130Pa.YePlasma polymerization inoda basa, yakakodzera kuyerera yekudzora modhi uye chiyero chekuyerera ichasarudzwa, kazhinji 10.100mL/min.Muplasma, mamorekuru emonomeri anoiswa ionized uye anoparadzaniswa nekubhomba kwezvimedu zvine simba, zvichikonzera zvidimbu zvinoshanda semaion uye majini anoshanda.Iwo anoshanda masisitimu akaiswa neplasma anogona kupinda muPlasma polymerization pane chinongedzo chegasi chikamu uye chakasimba chikamu.Iyo monomer ndiyo sosi yeprecursor yePlasma polymerization, uye iyo yekuisa reaction gasi uye monomer ichave nehumwe kuchena.

(3) Kusarudzwa kwekunakidzwa kwemagetsi

Plasma inogona kugadzirwa uchishandisa DC, yakakwirira-frequency, RF, kana microwave magetsi masosi kupa plasma nharaunda yepolymerization.Kusarudzwa kwesimba rekupa magetsi kunotemerwa zvichienderana nezvinodiwa zvechimiro uye kuita kwepolymer.

(4) Kusarudzwa kwekubuda kwemaitiro

Kune zvinodiwa zvepolymer, Plasma polymerization inogona kusarudza maviri ekuburitsa modhi: kuenderera kuburitsa kana pulse discharge.

(5) Kusarudzwa kwezviyereso zvekubuda

Paunenge uchiitisa Plasma polymerization, maparamita ekuburitsa anofanirwa kutariswa kubva kuplasma paramita, polymer zvivakwa uye chimiro chinodiwa.Hukuru hwesimba rinoshandiswa panguva yepolymerization inotarwa nehuwandu hwekamuri yekutsvaira, saizi ye electrode, monomer kuyerera uye chimiro, chiyero chepolymerization, uye chimiro chepolymer uye kuita.Semuenzaniso, kana iyo reaction chamber vhoriyamu iri 1L uye RF Plasma polymerization yakagamuchirwa, simba rekuburitsa rinenge riri muhuwandu hwe10 ~ 30W.Mumamiriro ezvinhu akadaro, iyo plasma inogadzirwa inogona kuungana kuti iite firimu rakatetepa pamusoro peiyo workpiece.Chiyero chekukura kwePlasma polymerization firimu inosiyana nemagetsi emagetsi, monomer mhando uye chiyero chekuyerera, uye maitiro ekugadzirisa.Kazhinji, chiyero chekukura chiri 100nm/min~1um/min.

(6) Parameter kuyerwa muPlasma polymerization

Iyo plasma paramita uye maitiro ekuita kuyerwa muPlasma polymerization anosanganisira: discharge voltage, discharge current, discharge frequency, Electron tembiricha, density, reaction group type uye concentration, etc.
