Preparation, Properties and Application of Miscanthus Nanocellulose as Coating Layer

Abstract

The data on the preparation of nanocellulose from organosolvent miscanthus pulp and its application as coating layer in the production of bag paper are reported. The influence of technological factors on the properties of nanocellulose films was determined. The obtained nanocellulose films had density up to 1.46 g/cm3, transparency up to 80%, crystallinity degree up to 77% and tensile strength up to 70 MPa. The properties of nanocellulose films studied by means of electron absorption spectra, XRD and AFM methods. The bag paper with consumption of nanocellulose of 5 g/m2 has mechanical properties of 12–68% higher and the elongation increases 2.9 times than paper without the use of surface treatment. The using of obtained nanocellulose as a coating layer exhibit great potential its application for improving fiber-based mechanical and barrier properties of paper and cardboard.
