In this study, we added m-CNF and SiO2 NPs to hydrogel adhesive to enhance mechanical and adhesive properties of it. After simply mixing all components, hydrogel adhesive was easily cured with UV polymerization. The result of PAA/m-CNF/SiO2 hydrogel was analyzed by Field Emission Scanning Electron Microscope (FE-SEM), Probe Tack Test, Peel Test, Universal Test Machine (UTM), Swelling Test. As the surface of m-CNF was replaced with carboxymethyl group, it could be dispersed without agglomeration in the polymer matrix. Since the hydroxyl groups of the SiO2 NPs and the carboxymethyl groups of m-CNF formed physical bonds, internal cohesion was increased. When SiO2 NPs are added, the viscosity of the solution can be controlled by mixing with m-CNF, which greatly contributed to the improvement of physical properties. |
