Abstract
Hydrogels contain a large amount of water; thus, they are jelly-like, soft, and fragile. Although hydrogels' stiffness and strength can be improved by introducing another network to form a double or interpenetrating network, these mechanical properties are still not enough as many applications demand even stiffer and stronger hydrogels. Different methods of reinforcing hydrogels have been proposed and published. In this research, cellulose microfiber isolated from pineapple leaf was used as the reinforcement for hydrogels. The reinforcing efficiency of the fiber was studied for both single and double networks through the compression test. Other properties such as morphology and swelling behavior of the reinforced hydrogels were also studied. A synergistic effect of the second network and the fiber on the reinforcement was observed. The improvement due to the effect of fiber loading of only 0.6 wt % was found to be as high as 150%. This is greater than that observed in some nanofiller systems. Thus, the fiber can be used as a green reinforcement for similar hydrogel systems.
