| چکیده | ||
| این پژوهش با هدف ارزیابی تأثیر تیمار نانوالیاف سلولز بر تغییرات رنگی آثار کاغذی انجام شد. در این پژوهش دو نوع سوسپانسیون نانوالیاف سلولز با غلظت 1 درصد وزنی و درصد خشکی 4% با آب و همچنین اتانل تهیه شد. پس از تیماردهی، نمونههای آماده شده طبق استاندارد TAPPI T 544 sp-03 تحت پیرسازی حرارتی- رطوبتی قرار گرفتند و آزمونهای رنگسنجی، سنجش pH، طیفسنجیATR-FTIR و میکروسکوپ SEM قبل و پس از پیرسازی انجام شد. بررسـی طیـفهـایATR-FTIR به‌دست آمده از نمونهها، نشان داد که به‌کارگیری تیمار نانوالیاف سلولز باعـث تخریـب سـاختار کاغذ نمیشود. پس از کاربرد دو نوع تیمار با نانوالیاف سلولز رنگ نمونهها روشنتر شده است، اما پس از پیرسازی تسریعی میزان روشنی نمونهها کاهش یافته است. تیره شدن رنگ نمونهها به دلیل قرارگرفتن آنها در شـرایط پیرسـازی تسـریعی ایجاد شده و تیمار نانوالیاف سلولز عامـل تغییر رنگ نبوده است. pH نمونهها پس از کاربرد هر دو نوع تیمار نانوالیاف سلولز افزایش پیدا کرد اما بعـد از پیرسـازی تسریعی، pH مقداری کاهش یافت. | ||

| چکیده [English] | ||
| The aim of this study was to evaluate the effect of cellulose nanofiber treatment on discoloration of historical papers. In this study, two types of cellulose nanofiber suspensions with a concentration of 1% by weight with water and ethanol were prepared. After treatment, the prepared samples were subjected to moist-heat aging according to TAPPI T 544 sp-03 standard and colorimetric, pH, ATR-FTIR spectroscopy and SEM microscopy were performed before and after aging. Examination of ATR-FTIR spectra obtained from the samples showed that the application of cellulose nanofiber treatment does not cause damage to the paper structure. After application of two treatments with cellulose nanofibers, the color of the samples became brighter, but after accelerated aging, the brightness of the samples decreased.The darkening of the color of the samples was caused by their exposure to accelerated aging conditions and the treatment of cellulose nanofibers did not cause discoloration. The pH of the samples increased after application of both types of cellulose nanofiber treatments, but after accelerated aging, the pH decreased slightly. | ||
