Ionogels are good candidate for smart materials with tunable thermal, mechanical and electrical properties. In our previous paper, we provided poly(N-isopropylacrylamide-co-N,N’-diethylacrylamide) (PNN) as a promising temperature-responsive ionogel, but the weakened mechanical durability has limited its application as stretchable materials. To overcome this drawback, we prepared the ionogel in double network structure by associating PNN with chitosan which plays a role as sacrificial network. By utilizing the sacrificial network that will form additional physical crosslinking of chain entanglement upon network breakage, we are able to enhance mechanical properties as well as preserving its thermal responsiveness. Furthermore, from the double network ionogels system, we attempted to load electroluminescent (EL) nanoparticles to make EL ionogels. Due to the ionic conductivity property of IL, prepared ionogels can show the luminescence when applied the alternating current.
