Ushbu tadqiqotda NIPS usullari yordamida polivinilxloridni PVX/polikarbonat PC aralashmasi membranalari tayyorlandi va Bovine Serum Albumin (BSA) eritmasining filtratsiyasi o’tgazilgan. Membrananing g'ovak o'lchamlari taqsimoti kichikroq teshiklar tomon siljidi, chunki membranalarda g;ovakning miqdori 50% gacha ko'tarildi va keyin kattaroq teshiklar tomon siljidi. Bundan tashqari, qorishma membranalarining gidrofilligi, valentlik kuchi va ishqalanishga chidamliligi yaxshilandi. Sof suv oqimi va BSAni rad etish, chunki membranalarning ishlash mezonlari PC mavjudligi tufayli yaxshilandi. Membranalarning antifouling xususiyatlari PC tarkibining ortishi bilan ortishi aniqlandi. Natijalar shuni ko'rsatdiki, PVX/PC aralashmasi membranalari toza PVX membranaga nisbatan yuqori samarali va ifloslanishga chidamli membranalardir.
