Porous double network gel with high toughness, high stretchability and fast solvent-absorption

Abstract

Using freeze-dry method, we fabricated porous double network gels with high toughness, high stretchability and fast solvent-absorption. When the freezing temperature was -20 °C and freezing time was 24 hours, pores with diameter around 300 μm could form in the gel. When the freezing temperature was lowered to −196 °C and freezing time was reduced to 10 minutes, monodisperse pores with diameter around 15 μm could form in the gel. We found out that both porous gels fabricated in different conditions can absorb solvent much more as well as much faster than nonporous gel. Furthermore, we found that the rupturing strain, stiffness and strength of the porous double network gels were all comparable to nonporous double network gel when containing the same amount of solvent. The unique combination of mechanical properties of porous double network gel may motivate new explorations of gels in practical applications.
