Nkhaniyi ikunena za kugwiritsidwa ntchito kwa mpweya wothamanga wa plasma kuti upangitse kulumikiza kwa mankhwala a poly(ethylene glycol) methyl ether methacrylate (PEGMA) pa polystyrene (PS) ndi poly(methyl methacrylate) (PMMA) ndi cholinga chopeza adlayer conformation yomwe imagonjetsedwa ndi mapuloteni adsorption.Chithandizo cha plasma chidachitika pogwiritsa ntchito dielectric barrier discharge (DBD) riyakitala yokhala ndi PEGMA ya zolemera zamamolekyulu (MW) 1000 ndi 2000, PEGMA (1000) ndi PEGMA (2000), ndikumezetsanidwa munjira ziwiri: (1) magulu othandizira. amapangidwa pa polima pamwamba kutsatiridwa ndi (2) kwambiri kuwonjezera zochita ndi PEGMA.Kuphatikizika kwa chemistry, mgwirizano, ndi mawonekedwe a malo omwe adalumikizidwa ndi PEGMA adadziwika ndi X-ray photoelectron spectroscopy (XPS), nthawi ya kuwuluka yachiwiri ya ion mass spectrometry (ToF-SIMS), ndi ma atomic force microscopy (AFM), motsatana. .The kwambiri coherently kumtengowo PEGMA zigawo ankaona kwa 2000 MW PEGMA macromolecule, DBD kukonzedwa pa mphamvu mlingo wa 105.0 J/cm(2) monga momwe ToF-SIMS zithunzi.Zotsatira za chemisorbed PEGMA wosanjikiza pama protein adsorption adawunikidwa poyesa kuyankha kwa bovine serum albumin (BSA) pogwiritsa ntchito XPS.BSA idagwiritsidwa ntchito ngati puloteni yachitsanzo kudziwa kulumikizidwa kwa macromolecular a PEGMA wosanjikiza.Pomwe malo a PEGMA(1000) adawonetsa kudyerera kwa mapuloteni, malo a PEGMA(2000) adawoneka kuti amatenga mapuloteni osayezeka, zomwe zimatsimikizira kukhazikika kwapamwamba kwa malo osawonongeka.
