Preparation and Application of Cellulose-Based and Chitosan-Based Materials

This Reprint centers on the preparation and application of cellulose-based and chitosan-based materials, responding to the global imperative of carbon peak and carbon neutrality to address catastrophic climate change. Against the backdrop of pursuing sustainable development, renewable and biodegradable biomass resources, particularly abundant natural polymers including cellulose, lignin, chitin, and collagen, have garnered extensive and growing attention in recent decades. These biomass feedstocks serve as the foundation for a diverse array of high-performance biomass-based materials, which exhibit broad and promising applications across critical sectors such as sustainable packaging, energy storage, and biomedical engineering. This Reprint brings together cutting-edge original research, comprehensive reviews, and insightful communications from global experts, focusing on the core themes of advanced preparation technologies, structural design, functional modification, and practical application expansion of cellulose-based and chitosan-based materials. This Reprint aims to showcase the latest advances, emerging trends, and future perspectives in the field, providing valuable guidance for researchers, engineers, and industry practitioners dedicated to advancing biomass-based material innovation, promoting the sustainable bioeconomy, and supporting global carbon neutrality goals.
