Double network(DN) hydrogels are soft but possess high strength and toughness through interpenetration of two different network. In this study, we prepared first network consisting of cellulose, carboxymethylcellulose sodium salt (CMCNa) and 2-hydroxyethyl cellulose(HEC), using citric acid(CA) as a crosslinker. The second network of K-carrageenan(KC) was sequentially incorporated to the first network. The DN gel synthesized in this research is a bio-degradable and bio-compatible hydrogel. The influence on the mechanical properties of concentration of CA(%) and ratio of cellulose : KC was investigated by Universal Technical Machine and rheometer.
