摘要：One of the most important issues for treatment of paper works is use of long-lasting (endurable) materials. In this study, Mechanical properties of Bacterial cellulose Nanofibers (BCN) for preservation of paper works are investigated. For this purpose, Suspension of BCN in Klucel-G polymeric matrix with doses of 0.5, 1, and 2 Wt% of dry matter were prepared and were coated on the pure cellulose paper (filter paper) by hydro-soluble casting method, and then tensile strength (TS) and folding endurance (FE) mechanical tests were performed. Also, in order to evaluate durability properties (long-lasting) of the cellulose fiber bio-nanocomposite, accelerated aging test was conducted in moist heat conditions. After performing mechanical test, obtained results were investigated and it was observed that the presence of this nanofibers in Klucel-G matrix, although lowers the initial mechanical properties (before aging), but increases durability of bio-nanocomposite compared to pure Klucel-G polymer matrix, and hence, as protective coatings, results in prevention of early aging. As a result, this prepared nanocomposite would have applications as a new reinforcing and endurable polymeric coating for preservation of paper works and prevention from further loss of their strength, and also there would be less need for retreatment.
