Biodegradable Nanoporous Polymer-based Composites for a Flexible Electronic Devices

Driven by escalating environmental concerns surrounding waste accumulation, biodegradable materials have gained widespread attention as sustainable alternatives. Among various biodegradable polymers, nanocellulose-based materials—including cellulose nanofibers, cellulose nanocrystals, and bacterial cellulose—possess outstanding physiochemical properties, such as a large specific surface area, exceptional mechanical strength, and inherent renewability. Consequently, they are being actively investigated for diverse high-value applications, including eco-friendly packaging, polymer composites, flexible electronic substrates, and biomedical devices. This review comprehensively examines the recent advancements in reinforcing the physical properties and tunability of biodegradability in nanocellulose-based systems. Furthermore, we highlight current research trends and outline future strategies for engineering sustainable, high-performance materials that seamlessly harmonize advanced functionality with environmental degradability.
