the key factor affecting pes membrane formation mechanism is the phase separation temperature of the lcst casting solutions.
عامل کلیدی موثر بر مکانیسم تشکیل غشاء pes دمای جداسازی فاز محلول های ریخته گری lcst است.

a new method was presented to prepare hydrophilic pes/spsf flat sheet membrane by a reverse thermally induced phase separation (rtips) method to enhance permeability and hydrophilicity. spsf was self made and was blended to improve the hydrophilicity of pes flat sheet membrane.
روش جدیدی برای تهیه غشای ورق تخت pes/spsf هیدروفیل به روش جداسازی فاز القایی حرارتی معکوس (rtips) برای افزایش قابلیت ترامدا و آب دوست بودن ارائه شد. spsf خود ساخته شده بود و برای بهبود هیدروفیلیته غشای ورق تخت pes مخلوط شد.

if we'd evolved in a vacuum, we would expect them to hit the ground simultaneously. if we were bacteria, constantly buffeted by thermal movements of molecules, it would be different, but we middle worlders are too big to notice brownian motion.
اگر ما در فضای تهی فرگشت می‌یافتیم ما انتظار می‌داشتیم که همزمان زمین بخورند. اگر باکتری بودیم، مرتب با حرکات گرمایی ملکول‌ها ضربه می‌خوردیم، در آن صورت باز هم به شکلی دیگر بود. ولی ما جهان میانه‌ای‌ها بسیار بزرگتر از آنیم که حرکت براونی را حس کنیم.

a novel slow–fast phase separation (sfps) process is proposed to fabricate the desirable ultrafiltrationdual-layer hollow fiber substrate for effective interfacial polymerization. by controlling the ratios of nonsolventsto volatile co-solvents in both the outer- and inner-layer dopes, the outer and inner layersundergo slow and fast coagulation, respectively, in the dry-jet wet-spinning co-extrusion process.the inner layer is highly porous for high solvent flux permeation, while the outer layer possesses asurface with nano-sized pores that have a sharp size distribution for effective thin film polymerization.the addition of polyvinylpyrrolidone in the outer dope further reduces the pore size, and enhancessurface hydrophilicity as well as mechanical strength. the substrate was cross-linked and subjected tointerfacial polymerization for fabricating thin-film composite (tfc) membranes. the effects of thesubstrate properties of various hollow fiber membranes from the sfps process on the tfc membranewere systematically investigated in terms of morphology and organic solvent nanofiltration (osn)performance. the membrane shows a 99.3% rejection of ramazol brilliant blue (mw: 626.54 g mol1)and a methanol flux of 14.4 l m2h1 at 16 bar.
