Cov txheej txheem polymerization ncaj qha ntawm cov ntshav

Cov txheej txheem ntawm Plasma polymerization yog qhov yooj yim rau ob qho tib si sab hauv electrode polymerization khoom siv thiab sab nraud electrode polymerization khoom siv, tab sis kev xaiv parameter tseem ceeb dua hauv Plasma polymerization, vim tias cov parameters muaj kev cuam tshuam ntau dua rau cov qauv thiab kev ua tau zoo ntawm cov yeeb yaj kiab polymer thaum lub sijhawm Plasma polymerization.

Cov kauj ruam ua haujlwm rau kev sib xyaw plasma ncaj qha yog raws li nram no:

(1) Siv lub tshuab nqus tsev

Lub tshuab nqus tsev keeb kwm yav dhau los ntawm polymerization nyob rau hauv lub tshuab nqus tsev yuav tsum tau pumped mus rau 1.3 × 10-1Pa. Rau cov tshuaj tiv thaiv polymerization uas xav tau cov kev cai tshwj xeeb rau kev tswj cov pa oxygen lossis nitrogen, qhov kev xav tau ntawm lub tshuab nqus tsev keeb kwm yav dhau los yog siab dua.

(2) Cov tshuaj tiv thaiv monomer lossis cov roj sib xyaw ntawm cov roj nqa thiab monomer

Qhov degree nqus tsev yog 13-130Pa. Rau Plasma polymerization uas xav tau kev ua haujlwm, yuav tsum xaiv hom kev tswj kev ntws thiab tus nqi ntws kom tsim nyog, feem ntau yog 10.100mL / min. Hauv plasma, cov monomer molecules yog ionized thiab dissociated los ntawm kev foob pob ntawm cov khoom siv zog, ua rau cov khoom siv nquag xws li ions thiab cov noob nquag. Cov khoom siv nquag uas plasma ua haujlwm tuaj yeem dhau los ntawm Plasma polymerization ntawm qhov sib txuas ntawm cov roj theem thiab cov khoom khov. Lub monomer yog qhov chaw ntawm precursor rau Plasma polymerization, thiab cov roj teb thiab monomer yuav tsum muaj qee qhov kev huv.

(3) Kev xaiv ntawm lub zog fais fab

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

(4) Kev xaiv hom kev tso tawm

Rau cov kev xav tau polymer, Plasma polymerization tuaj yeem xaiv ob hom kev tso tawm: kev tso tawm tas mus li lossis kev tso tawm ntawm lub zog.

(5) Kev xaiv cov kev tso tawm

Thaum ua Plasma polymerization, cov kev ntsuas tawm yuav tsum tau xav txog los ntawm cov kev ntsuas plasma, cov khoom polymer thiab cov qauv xav tau. Qhov loj ntawm lub zog siv thaum lub sijhawm polymerization yog txiav txim siab los ntawm qhov ntim ntawm lub chamber nqus tsev, qhov loj ntawm electrode, monomer flow rate thiab cov qauv, polymerization rate, thiab polymer qauv thiab kev ua tau zoo. Piv txwv li, yog tias qhov ntim ntawm lub chamber tshuaj tiv thaiv yog 1L thiab RF Plasma polymerization raug txais yuav, lub zog tawm yuav nyob rau hauv qhov ntau ntawm 10 ~ 30W. Nyob rau hauv cov xwm txheej zoo li no, cov plasma tsim tuaj yeem sib sau ua ke los ua ib zaj duab xis nyias nyias ntawm qhov chaw ua haujlwm. Qhov nrawm ntawm Plasma polymerization zaj duab xis sib txawv nrog lub zog muab hluav taws xob, hom monomer thiab flow rate, thiab cov txheej txheem. Feem ntau, qhov nrawm ntawm kev loj hlob yog 100nm / min ~ 1um / min.

(6) Kev ntsuas parameter hauv Plasma polymerization

Cov txheej txheem plasma thiab cov txheej txheem uas yuav tsum ntsuas hauv Plasma polymerization suav nrog: qhov hluav taws xob tawm, tam sim no tawm, zaus tawm, Qhov kub ntawm Electron, qhov ceev, hom pab pawg tshuaj tiv thaiv thiab kev sib sau ua ke, thiab lwm yam.
