Plasma ncaj qha polymerization txheej txheem

Cov txheej txheem ntawm Plasma polymerization yog qhov yooj yim rau ob qho tib si hauv cov khoom siv hluav taws xob polymerization thiab cov khoom siv hluav taws xob sab nraud polymerization, tab sis kev xaiv qhov ntsuas yog qhov tseem ceeb dua hauv Plasma polymerization, vim tias qhov tsis muaj qhov cuam tshuam ntau dua rau cov qauv thiab kev ua haujlwm ntawm cov yeeb yaj kiab polymer thaum lub sij hawm Plasma polymerization.

Cov kauj ruam ua haujlwm rau plasma polymerization ncaj qha yog raws li hauv qab no:

(1) Vacuuming

Lub tshuab nqus tsev tom qab ntawm polymerization nyob rau hauv lub tshuab nqus tsev yuav tsum tau pumped rau 1.3 × 10-1Pa.Rau cov tshuaj tiv thaiv polymerization uas xav tau tshwj xeeb rau kev tswj cov pa oxygen lossis nitrogen cov ntsiab lus, qhov kev xav tau ntawm lub tshuab nqus tsev tom qab yog ntau dua.

(2) Them cov tshuaj tiv thaiv monomer los yog cov roj sib xyaw ntawm cov cab kuj roj thiab monomer

Lub tshuab nqus tsev kawm ntawv yog 13-130Pa.Rau Plasma polymerization yuav tsum tau ua hauj lwm, tsim nyog txaus tswj hom thiab txaus tus nqi yuav tsum tau xaiv, feem ntau 10.100mL / min.Hauv plasma, monomer molecules yog ionized thiab dissociated los ntawm bombardment ntawm lub zog hais, uas ua rau active hais xws li ions thiab active noob.Cov khoom nquag ua haujlwm los ntawm plasma tuaj yeem nkag mus rau Plasma polymerization ntawm qhov cuam tshuam ntawm cov roj theem thiab cov theem khoom.Lub monomer yog lub hauv paus ntawm precursor rau Plasma polymerization, thiab cov input tshuaj tiv thaiv roj thiab monomer yuav tsum muaj tej yam purity.

(3) Kev xaiv ntawm excitation fais fab mov

Plasma tuaj yeem tsim los siv DC, high-frequency, RF, lossis microwave fais fab qhov chaw los muab cov plasma ib puag ncig rau polymerization.Kev xaiv cov khoom siv hluav taws xob yog txiav txim siab raws li qhov yuav tsum tau ua rau cov qauv thiab kev ua haujlwm ntawm cov polymer.

(4) Xaiv hom kev tso tawm

Rau cov kev xav tau ntawm cov khoom siv polymer, Plasma polymerization tuaj yeem xaiv ob hom kev tso tawm: kev tawm mus tas li lossis cov mem tes tawm.

(5) Kev xaiv ntawm cov khoom pov tseg

Thaum ua cov txheej txheem plasma polymerization, cov khoom pov tseg yuav tsum tau txiav txim siab los ntawm cov txheej txheem plasma, cov khoom siv polymer thiab cov qauv tsim.Qhov loj ntawm lub zog siv thaum lub sij hawm polymerization yog txiav txim los ntawm lub ntim ntawm lub tshuab nqus tsev chamber, electrode loj, monomer txaus tus nqi thiab qauv, polymerization tus nqi, thiab polymer qauv thiab kev ua tau zoo.Piv txwv li, yog tias cov tshuaj tiv thaiv chamber ntim yog 1L thiab RF Plasma polymerization tau txais, lub zog tawm yuav nyob rau hauv thaj tsam ntawm 10 ~ 30W.Nyob rau hauv cov xwm txheej zoo li no, plasma generated tuaj yeem sib sau ua ib zaj duab xis nyias ntawm qhov chaw ua haujlwm.Txoj kev loj hlob ntawm Plasma polymerization zaj duab xis sib txawv nrog lub zog mov, hom monomer thiab ntws tus nqi, thiab cov txheej txheem txheej txheem.Feem ntau, qhov kev loj hlob yog 100nm / min ~ 1um / min.

(6) Parameter ntsuas hauv Plasma polymerization

Cov txheej txheem plasma thiab cov txheej txheem uas yuav tsum tau ntsuas hauv Plasma polymerization muaj xws li: qhov hluav taws xob tawm, tawm tam sim no, tawm zaus, hluav taws xob kub, qhov ntom ntom, cov tshuaj tiv thaiv pawg hom thiab concentration, thiab lwm yam.
