In this paper, polyvinyl alcohol/polyaniline/polypyrrole/TiO₂(PVA/PANI/PPy/TiO₂) hybrid hydrogels were synthesized by the combination of sol-gel technique, in-situ oxidation polymerization and freezing-thawing method with polyvinyl alcohol (PVA), aniline (ANI) and pyrrole (Py) and butyl titanate (TBOT) as raw materials. It is found that the hybrid hydrogel has excellent mechanical properties and electrical conductivity. When n(ANI):n(Py) is 8:2 and the volume of TBOT is 100 μL, the maximum compressive stress of the hybrid hydrogel is 2.45 MPa. Meanwhile, the hybrid hydrogel has good conductivity. Under the action of external electrical source, the bulb could be lighted. When n(ANI):n(Py) is 2:8 and the volume of TBOT is 150 μL, the hybrid hydrogel has the highest conductivity of 0.25 S/m. The hybrid hydrogel is expected to have wide applications in the fields of flexible wearable electronic devices, safe ion batteries, sensors and biological devices.
