Plasma itaziguye

Inzira ya Plasma polymerisation iroroshye cyane kubikoresho byimbere ya electrode yimbere hamwe nibikoresho bya electrode yo hanze, ariko guhitamo ibipimo nibyingenzi muri Plasma polymerisation, kuko ibipimo bigira ingaruka zikomeye kumiterere no mumikorere ya firime ya polymer mugihe cya polymerisime.

Intambwe yimikorere ya plasma polymerisation itaziguye nuburyo bukurikira:

(1) Vacuuming

Icyuho cyinyuma cya polymerisiyasi mubihe bya vacuum bigomba kuvomerwa kuri 1.3 × 10-1Pa.Kubisubizo bya polymerisation bisaba ibisabwa byihariye mugucunga ogisijeni cyangwa azote, icyuho cya vacuum gisabwa ni kinini.

(2) Kwishyuza reaction ya monomer cyangwa gaze ivanze ya gaze itwara na monomer

Impamyabumenyi ya vacuum ni 13-130Pa.Kuri plasma polymerisation isaba akazi, uburyo bukwiye bwo kugenzura imigendekere nigipimo cyo gutemba bizatoranywa, muri rusange 10.100mL / min.Muri plasma, molekile ya monomer irahuzwa kandi igatandukanywa no guturika ibisasu bitera ingufu, bikavamo ibice bikora nka ion na gen zikora.Ibice bikora bikoreshwa na plasma birashobora gukorerwa Plasma polymerisiyasi mugice cya gaze nicyiciro gikomeye.Monomer niyo soko yabanjirije Plasma polymerisation, kandi gaze yinjiza gaze na monomer bigomba kugira ubuziranenge.

(3) Guhitamo amashanyarazi ashimishije

Plasma irashobora kubyara hakoreshejwe DC, inshuro nyinshi, RF, cyangwa ingufu za microwave kugirango itange plasma ya polymerisation.Guhitamo amashanyarazi bigenwa hashingiwe kubisabwa kugirango imiterere n'imikorere ya polymer.

(4) Guhitamo uburyo bwo gusohora

Kubisabwa na polymer, Plasma polymerisation irashobora guhitamo uburyo bubiri bwo gusohora: gusohora guhoraho cyangwa gusohora pulse.

(5) Guhitamo ibipimo byo gusohora

Mugihe ukora plasma polymerisation, ibipimo byo gusohora bigomba gusuzumwa uhereye kubintu bya plasma, imiterere ya polymer nibisabwa.Ubunini bwimbaraga zikoreshwa mugihe cya polymerizasiyo bigenwa nubunini bwicyumba cya vacuum, ingano ya electrode, umuvuduko wa monomer nuburyo, igipimo cya polymerisation, nuburyo bwa polymer nuburyo bukora.Kurugero, niba reaction ya chambre yububiko ari 1L na RF Plasma polymerisation yemewe, imbaraga zo gusohora zizaba ziri hagati ya 10 ~ 30W.Mubihe nkibi, plasma yakozwe irashobora kwegeranya kugirango ikore firime yoroheje hejuru yakazi.Iterambere ryubwiyongere bwa firime ya Plasma polymerisation iratandukanye hamwe nogutanga amashanyarazi, ubwoko bwa monomer nigipimo cyimbere, hamwe nuburyo ibintu bigenda.Mubisanzwe, umuvuduko wubwiyongere ni 100nm / min ~ 1um / min.

(6) Ibipimo bya Parameter muri Plasma polymerisation

Ibipimo bya plasma nibipimo bigomba gupimwa muri Plasma polymerisation harimo: gusohora voltage, gusohora amashanyarazi, inshuro zisohora, ubushyuhe bwa Electron, ubucucike, ubwoko bwa reaction hamwe nibitekerezo, nibindi.
