چکیده

بسپارهای متخلل امولسیونی عامل‌دار کاربردهای دارویی و صنعتی متعددی دارند و به‌عنوان مواد نوین برای جداسازی مورد توجه هستند. در این تحقیق ابتدا سنتز امولسیونی پلی (استایرن- دی وینیل بنزن) انجام شد، سپس اثر افزایش گروه عاملی سدیم استایرن سولفونیک اسید بر میزان آب‌دوستی سطح بسپار متخلخل امولسیونی پلی (استایرن- دی وینیل بنزن) بررسی شد. از میکروسکوپ الکترونی روبشی برای بررسی ریخت‌شناسی سطح و تعیین میزان توزیع اندازۀ قطر حفره‌های سطحی و آزمون طیف‌سنجی پراش انرژی پرتو ایکس برای بررسی وجود اتم‌های گوگرد و سدیم در سطح بسپار متخلخل عامل‌دارشده و از دستگاه اندازه‌گیری زاویۀ تماس با قابلیت عکس‌برداری از قطره و دارای نرم‌افزار سنجش زاویۀ تماس قطره با سطح برای بررسی میزان آب‌دوستی سطح بسپار متخلخل امولسیونی پلی (استایرن- دی وینیل بنزن) عامل‌دارشده، استفاده شد. افزایش سدیم استایرن سولفونیک اسید در شکل و اندازۀ حفره‌های تشکیل‌شده تأثیری ندارد؛ ولی میزان آب‌دوستی نمونه‌ها با افزایش عامل سولفونه در فاز آبی افزایش یافت و مقدار مناسب درصد سدیم استایرن سولفونیک اسید در فاز آبی به‌عنوان عامل سولفونه در حدود 2 درصد بود و با افزایش بیشتر از 2 درصد تغییرات افزایشی کمی در میزان آب‌دوستی سطح بسپار متخلخل امولسیونی پلی (استایرن- دی وینیل بنزن) عامل‌دارشده، به‌و‌جود آمد و تقریباً نمودار تغییرات خطی با شیب ناچیز شد.

چکیده [English]

Emulsifying porous polymers have many pharmaceutical and industrial applications and are considered as new materials for separation. In this research, first the emulsion synthesis of poly (styrene-di vinylbenzene) was performed and then the effect of increasing the functional group of sodium styrene sulfonic acid on the hydrophilicity of the emulsion porous polymer poly (styrene-divinylbenzene) was investigated. Scanning Electron Microscope to study surface morphology and determine the size distribution of surface cavities and Energy Dispersive X-ray analysis test to investigate the presence of sulfur and sodium atoms in the surface of functionalized porous polymer and contact angle measuring device with Coupled-Camera Devise(CCD) and with software for measuring the contact angle of droplet contact with the surface to evaluate
the hydrophilicity of the surface of polymerized emulsion polymer poly
(styrene-divinylbenzene) were used. Increasing sodium styrene sulfonic acid has no effect on the shape and size of the cavities formed, but the hydrophilicity of the samples increased with increasing sulfone factor in the aqueous phase and the appropriate percentage of sodium styrene sulfonic acid in the aqueous phase was about 2%. With an increase of more than 2%, a slight increase in the hydrophilicity of the surface of the emulsion porous polymer poly (styrene-divinylbenzene) was activated and the graph became almost flat with slope changes insignificant.
