Abstract

Background and Objectives: Mechanically isolated cellulose nanofibers (MCNF), Bacterial cellulose nano-fibers (BCNF) and chitin nanofibers (ChNF), as nano-polysaccharides, have attracted much attention of researchers during two past decades due to biocompatibility, good barrier (barrier properties against water vapor, oxygen, and etc. ), high mechanical properties as well as low cost of their raw materials. Non-thermal plasma treatment (Cold plasma) is an effective way to modify the surfaces of a wide variety of materials. In this study, the effect of Cold plasma on the physical and mechanical properties of three types of Nano-papers prepared with MCNF, BCNF and ChNF were studied. Materials and Methods: To study the effect of Cold plasma on mentioned Nano-papers, four plasma treatment times of 0, 3, 6, and 9 minutes have been selected as variables. WCNF, BCNF and ChNF in gel form were prepared from Nano Novin Polymer Co. (Iran). To produce Nano-paper from different nano-fibers, vacuum filtration method was used. Morphological properties of Nano-paper were determined by scanning electron microscopy (SEM). Water vapor permeability (WVP), solubility in water, surface color of papers, transparency and the mechanical properties of fabricated Nano-papers were investigated. Results: Scanning electron microscope (SEM) images showed that the average diameter of MCNF, BCNF, and ChNF Nano-papers were 35, 48, and 26 nm, respectively. Plasma treatment increased the whiteness of specimens. As the result of plasma treatment, WVP decreased at lower treatment time (3 min), while this property increased within treatment time over 3 min. Plasma did not have considerable effect of water solubility of specimens. The specimens treated with 3 min showed the highest transparency. All treated specimens showed less mechanical properties compared to the control one. Conclusion: In general, plasma could improve the properties of Nano-papers at lower treatment time while longer treatment times had negative effect on specimens’ characteristics.
