Researchers demonstrate plant-derived cellulose nanocrystals can be sustainable adhesive alternative

February 25, 2020 |

In Japan, in a study published in Advanced Materials, researchers at Aalto University, the University of Tokyo, Sichuan University, and the University of British Columbia have demonstrated that plant-derived cellulose nanocrystals (CNCs) can form an adhesive that fully integrates the concepts of sustainability, performance, and cost which are generally extremely challenging to achieve simultaneously.

Unlike Superglue, the new eco glue develops its full strength in a preferred direction, similar to “Peel and Stick” adhesives. When trying to separate the glued components along the principal plane of the bond, the strength is more than 70 times higher when compared to the direction perpendicular to that plane. All of this means that just a single drop of the “eco” glue has enough strength to hold up to 90kg weight but can still be easily removed by the touch of a finger, as needed.
