Abstract: The present disclosure provides an adhesive composition including a silicone-based adhesive and cellulose nanocrystals dispersed in the silicone-based adhesive. The present disclosure also provides an article including a substrate and a layer of the adhesive composition adhered to the substrate. Further, the present disclosure provides a method of making an adhesive composition. The method comprises mixing cellulose nanocrystals in a silicone-based adhesive to disperse the cellulose nanocrystals. The present disclosure additionally provides a method of making an article including disposing a layer of the adhesive composition on a substrate. The presence of the cellulose nanocrystals advantageously increases the water uptake capacity of the silicone-based adhesive while maintaining acceptable adhesive performance.
