Investigation Of Swelling Ratio And Textures Analysis Of Acrylamide-Nanocellulose Corncobs Hydrogel

Corncobs have a high level of cellulose hence making it suitable to be used as the main ingredient in making hydrogels. Hydrogel are crosslinked polymers capable of absorbing water hundreds to thousands of times their dry weight, but are insoluble in water due to the three-dimensional structure of the polymer network. Hydrogel can be synthesized using corncobs cellulose and acrylate-acrylamide with chemical crosslinking methods. This study aims to determine the effect of adding corncobs cellulose and acrylate-acrylamide on hydrogel ability to swelling ratio, gel fraction and texture analysis. Nanohydrogel were synthesized by cellulose concentration by 5- 25% while acrylamide was varied 10,12 and 16 %. The treatment concentration ratio of nanocellulose solution to acrylamide also showed a significantly different effect at 5% level. The optimum hydrogel synthesis was the treatment of 10 % cellulose ratio and 16% acrylamide ratio which has a swelling ability of 15152.3% (g/g) and gel fraction 56.6%. The increasing the concentration of cellulose caused the hardness value to be higher but the springiness value tends to decrease. Morphology analysis showed the surface of hydrogels that are porous, has lumps and forms a three-dimensional tissue.
