The increasing utilization of petroleum-based plastics, which has significantly enhanced human convenience, has intensified the issue of plastic waste management. As a result, there has been a growing interest in biodegradable polymers. However, these polymers have high gas barrier issues, making them less suitable for food packaging films. To address this issue, cellulose nanofiber (CNF) is commonly used as a filler to enhance the gas barrier properties of biodegradable polymers, with higher CNF content leading to better gas barrier properties. However, CNFs exhibit strong intermolecular interactions due to extensive hydrogen bonding on their surfaces, making them difficult to coat onto biodegradable polymers. This study used a compatibilizer to reduce these strong interactions and optimize the conditions for maximizing the CNF content. This approach is expected to improve coating properties and form compelling gas barrier films for food packaging.
