Environment-friendly Bio-Based Epoxy Resin/cellulose Nanofiber Film for Triboelectric Nanogenerator Application

The petroleum-based derived materials are used in industrial applications due to their specific properties. However, they are increasing environmental concerns because they produce toxic gases when disposed of and burned [1, 2]. Thus, biomass-derived epoxy resins have gained significant attention due to their low-cost, easy synthetic route, and environmentally friendly. CNF can be a promising approach for the future generation to design all-green materials with bio-mass-derived resins for various applications [3, 4]. This research aims to explore the strategies for hydrophilic CNF film to make it useable for high-performance applications. In this regard, the bio-based vanillin-derived epoxy resin was proposed to improve hydrophobicity of CNF film, making them ideal for TENG applications.
