Carboxymethylated cellulose nanofiber (CM-CNF) was incorporated into the polyacrylamide (PAAm) to make composite hydrogel with high tensile strength. Cellulose is the most abundant renewable natural polymer. Especially, CNFs are promising filler for effective reinforcement of composites due to their large surface area, high aspect ratio, and high Young’s modulus. PAAm has been used in various fields due to its promising optical transparency but its mechanical properties need to be improved. The composite hydrogel of CM-CNF/PAAm showed the enhanced mechanical strength maintaining its adequate transparency. The CM-CNF/PAAm composite hydrogel can be used in biomedical engineering and soft electronics in the future.
