| DOR:98.1000/1735-0913.1397.33.531.65.4.32.1606 کاربردهای نانومواد تجدیدپذیر، مانند نانوالیاف سلولز(CNFs)، به دلیل خواص منحصر به فرد شامل: سطح ویژه بالا، ضریب لاغری بالا، زیست تخریپ‌پذیر، دسترسی آسان و گروه‌های هیدروکسیل واکنش‌پذیر موجود در سطح اخیراْ مورد توجه بسیاری قرارگرفته است. هدف از این پژوهش، ساخت فیلترهای نانویی تجدیدپذیر هوا با استفاده از CNFs اصلاح شده با فتالیمید می‌باشد. چون فتالیمید حاوی گروه‌های آمینی می‌باشد که برای جذب دی‌اکسید کربن لازم می‌باشد. در این تحقیق از روش خشک‌کن انجمادی برای حذف مستقیم آب از ژل CNFs خالص و اصلاح شده با فتالیمید استفاده شد همچنین خواص آئروژل‌های CNFsخالص و اصلاح شده با فتالیمید به منظور جذب دی اکسید کربن بررسی گردید. اصلاح CNFs با فتالیمید در اسید استیک با نسبت CNFs به فتالیمید 1: 0، 1: 0.5، 1: 1 و 1: 1.5درصد وزنی انجام شد. خصوصیات شیمیایی و مورفولوژیکی CNFs اصلاح شده با تکنیک‌های مختلفی شامل SEM، FTIR-ATR، XRD و TGA بررسی شد. بررسی انجام شده توسط SEM هیچ تغییری در ابعاد و ساختار CNFs اصلاح شده نشان نداد. حضور فتالیمید با ایجاد پیک‌های جدید NH2، C-N و استر (〖COO〗^-) بر روی CNFs اصلاح شده با استفاده از آزمون طیف سنجی ATR-FTIR تأیید شد. همچنین، نتایج TGA نشان داد که با افزایش مقدار فتالیمید، پایداری حرارتی کاهش می-یابد که نشان‌دهنده واکنش‌پذیری گروهای عاملی فتالیمید باCNFs است. به علاوه، بیشترین جذب دی اکسیدکربن مربوط به فتالیمید 1.5 درصد حدود 50 درصد بود | ||

| چکیده [English] | ||
| The applications of renewable nanomaterial’s, such as cellulose nanofibers (CNFs), have recently been of great interest due to their unique properties, including high surface area, high aspect ratio, biodegradable, easy access and reactive hydroxyl groups on the surface. The purpose of this study was to fabricate refined air nano filters using phthalimide- modified CNFs. Because phthalimide contains amine groups that are needed to adsorb carbon dioxide. In this study, a freeze drying method was used for direct removal of water from pure CNFs gel and phthalimide -modified. Also, the properties of pure CNFs aerogels and phthalimide-modified (containing amine groups) were investigated to adsorption carbon dioxide. Modification of CNFs with phthalimide in 4% (v/v) acetic acid, with ratios of CNFs to phthalimide 1: 0, 1: 0.5, 1: 1 and 1: 1.5 wt %. Chemical properties and morphology of modified CNFs were investigated using various techniques including SEM, FTIR-ATR, XRD and TGA. Based on the results, the SEM test did not show any change in the size and structure of the modified CNFs. The presence of phthalimide was confirmed by the creation of new pitches NH2, C-N and ester 〖COO〗^- on modified CNFs using the ATR-FTIR spectroscopy test. Also, the results of TGA indicated that increasing the amount of phthalimide reduces the thermal stability, indicating the reactivity of the functional groups of phthalimide with CNFs. In addition, the highest carbon dioxide adsorption of 1.5% phthalimide was about 50%. | ||
