Aqueous Cellulose Solution Adhesive

In the context of sustainable development, research on a biomass-based adhesive without chemical modification as a substitute for petroleum-based adhesive is now crucial. It turns out to be challenging to guarantee a simple and sustainable method to produce high-quality adhesives and subsequently manufacture multifunctional composites. Herein, the inherent properties of cellulose were exploited to generate an adhesive based on a cellulose aqueous solution. The adhesion is simple to prepare structurally and functionally complex materials in a single process. Cellulose-based daily necessities including straws, bags, and cups were prepared by adhering cellulose films, and smart devices like actuators and supercapacitors assembled by adhering hydrogels were also demonstrated. In addition, the composite boards bonded with natural biomass wastes, such as wood chips, displayed significantly stronger mechanical properties than the natural wood or commercial composite boards. Cellulose aqueous adhesives provide a straightforward, feasible, renewable, and inventive bonding technique for material shaping and the creation of multipurpose devices.
