| چکیده | ||
| هدف از تحقیق حاضر، مدلسازی و بهینهسازی پارامترهای دستگاه الکتروریسی برای تولید غشاء نانوالیافی با کاربرد در سیستمهای غشایی از پلیمر پلیسولفون (PSF) با استفاده از روش سطح پاسخ میباشد. برای این منظور، تاثیر ولتاژ (18-12 کیلو ولت)، سرعت جریان محلول پلیمری (6/0–3/0 میلیلیتر در ساعت) و فاصله بین سوزن و جمع کننده (5/17-5/10 سانتیمتر) و اثر سورفکتانت غیر یونی Triton x-100 (TR-100) بر مورفولوژی و ساختار غشاء نانوالیافی مورد بررسی قرار گرفت. شرایط بهینه برای تولید نانوالیاف به این صورت میباشد: ولتاژ اعمال شده 31/16 کیلوولت، سرعت جریان محلول پلیمری 39/0 میلیلیتر در ساعت و فاصله الکتروریسی 45/15 سانتیمتر. تصاویر میکروسکوپ الکترونی روبشی (SEM) نشان داد با افزودن سورفکتانت، قطر نانوالیاف حدود 20 درصد کاهش یافته و خواص مورفولوژیکی نانوالیاف بهبود یافته و نانوالیاف یکدست و همگن تولید گردیده است. زاویه تماس غشاءهای نانوالیافی مورد ارزیابی قرار گرفت و نتایج بیانگر آبگریز بودن هر دو غشاء (PSF و PSF/TR-100) میباشد. | ||

| چکیده [English] | ||
| The scope of this research was to model and optimize the electrospun parameters for the production of nanofiber membrane from polysulfone (PSF) polymer using the response surface methodology (RSM) with application in membrane systems. For this purpose, the influence of applied voltage (12-18 KV), flow rate (0.3-0.6 mL/h), the distance between needle and collector (10.5-17.5 cm) and effect of non-ionic surfactant Triton x-100 (TR-100) on the morphology and structure of nanofibers membrane was investigated. The optimal conditions for the fabrication of nanofibers were found to be as follow: the voltage 16.31 kV, the flow rate 0.39 mL/h, and the spinning distance 15.45 cm. The results of SEM demonstrated that with the addition of the surfactant, the fiber diameter reduced about 20% and the morphological properties of PSF nanofiber improved and homogeneous nanofibers have been produced. The contact angle of the developed nanofibers demonstrated that their surfaces were hydrophobic (PSF and PSF/TR-100). | ||
