Development of Multifunctional Paper Using Lignocellulosic Nanofiber-Reinforced Coatings

Abstract

Lignocellulosic nanofibers (LCNFs) have been recognized as promising candidates for multifunctional biological coatings. In this work, LCNFs were produced in a one-pot approach from high yield pulp (HYP) with different meshes using polymerizable deep eutectic solvent (DES) comprising choline chloride and acrylic acid. The DES-treatment did not alter the chemical properties of LCNFs, and employment of this LCNF/DES coating endowed the paper with improved hydrophobicity, tensile-strain, and electrical conductivity. Of particular interest is that the LCNF60/DES-coated paper presented outstanding fireresistant properties. This work contributes knowledge to develop an eco-friendly and inexpensive approach by using the most abundant bioresource, lignocellulosic biomass, to produce multifunctional paper and advance the development of the application of LCNFs.

Preparation and Properties of Modified Lignin/Triphenol Epoxy Composite Coatings for Superhydrophobicity and Corrosion Protection

“…In previous studies on lignin-based functional materials, researchers have mostly focused on the bacterial degradation of lignin and the application of lignin in wastewater treatment, energy storage, and renewable energy, which greatly limits its application in high value-added products. Therefore, based on the chemical properties of lignin, which is rich in aromatic rings, it is of great significance to utilize lignin and its derivatives to develop a variety of new functional materials, especially to construct UV-resistant , and superhydrophobic materials , with a variety of properties . Hammer et al prepared a novel organic–inorganic hybrid coating using a siloxane-gel method followed by the addition of lignin, which improved the mechanical strength, thermal stability, and hydrophobicity of the siloxane-PMMA coatings while maintaining the high anticorrosive properties of the coatings.…”
