Abstract
Illustrative embodiments of cellulose nanocrystal modification for adsorbents and sensors are disclosed. In at least one illustrative embodiment, a method of modifying cellulose nanocrystals for use in water-based applications may include obtaining sulfated cellulose nanocrystals (CNCs). The method may also include modifying the CNCs with a silane such as an alkylsilane (e.g., an aminoalkyl silane such as 3-aminopropyl-triethoxysilane (APTES)) to obtain modified CNCs. The modified CNCs enable increased hydrolytic stability (e.g., in a resulting structure, such as a film, coating, gel, or fiber(s), formed from the modified CNCs as compared to a structure formed from the unmodified CNCs). Additionally, the method may include using the modified CNCs in a water-based application.
