چکیده

هدف این پژوهش، ساخت فیلترهای نانویی برای جذب ذرات معلق کوچک‌تر از 5/2 میکرون موجود در هوا با استفاده از نانوالیاف سلولز اصلاح‌شده با فتالیمید است. اصلاح نانوالیاف سلولز با فتالیمید در اسید استیک با نسبت نانوالیاف سلولز به فتالیمید 0:1، 1: 5/0، 1: 1 و 1: 5/1 درصد وزنی انجام گرفت. بررسی توسط آزمون میکروسکوپ الکترونی روبشی نشان داد که در اثر اصلاح هیچ تغییر معنی‌داری در ابعاد و ساختار نانوالیاف سلولز ایجاد نمی‌شود، اما با افزایش مقدار فتالیمید سطح ویژه افزایش می‌یابد، درحالی ‌که تخلخل و قطر منافذ کاهش می‌یابد. همچنین نتایج تأثیر درجۀ حرارت بر میزان جذب ذرات معلق نشان داد که بیشترین جذب ذرات معلق کمتر از 1/0 میکرون مربوط به نانوالیاف سلولزی اصلاح‌شده با فتالیمید 5/1 درصد و دمای 65 درجه سلسیوس (76 درصد) بود. اما جذب ذرات معلق بزرگ‌تر از 3/0 میکرون برای همۀ نانوفیلترهای حاصل از نانوالیاف سلولزی خالص و اصلاح‌شده به‌طور جزئی افزایش یافت.

چکیده [English]

The purpose of this study was to fabricate nano filters to adsorb particulate matters less than 2.5 μm using phthalimide modified cellulose nanofibers. Modification of cellulose nanoparticles with phthalimide was performed on acetic acid with the cellulose to phthalimide nanofiber ratios of 1:0, 1:0.5, 1:1 and 1:1.5 wt%. Modified cellulose nanofibers were evaluated by various techniques including SEM and ZP (zeta potential). Finally, cellulose nanofibers, both pure and unmodified, were evaluated for the adsorption of particulate matters and compared with the control filter (HEPA). SEM analysis showed no significant change in the size and structure of cellulose nanofibers due to modification, but with increasing phthalimide content, the specific surface area increased while porosity and pore diameter decreased. The results of the effect of temperature on the adsorption of particulate matters showed that the highest adsorption of particulate matters less than 0.1 μm was related to 1.5% phthalimide-modified cellulose nanofibers and 65°C (76%). However, the adsorption of particulate matter was above 0.3 μm for all purified and modified cellulose nanofibers.
