| Abstract:As a novel bio-based material， nanocellulose exhibits distinctive attributes including renewability， degradabiility， high specific surface area， and exceptional mechanical performance. However， its surface contains abundant hydrophilic hydroxyl groups， which limits its application in hydrophobic-olephoic fields. Consequently， the hydrophobic-oleophobic functionalization modification of nanocellulose has progressively emerged as a research focus among scientists. In this paper， the principles， methodologies， and applications of hydrophobic-oleophobic functionalization modification of nanocellulose were systematically reviewed， while the characteristic features of products derived from distinct modification approaches were categorized. Applications of hydrophobic-oleophobic modified nanocellulose in food packaging， textile industries， and paper manufacturing were critically evaluated. Technical bottlenecks hindering the scaled application of these materials were analyzed， and future development directions were prospected to provide theoretical foundations for designing high-performance nanocellulose-based hydrophobic-oleophobic systems. |
