Abstract Burns can cause severe damage to the skin due bacterial infection and inflammation. Although conductive hydrogels as electroactive burn‐wound dressings achieve remarkable effects on accelerating wound healing, issues such imbalance between their high conductivity mechanical properties, easy dehydration, low transparency must be addressed. Herein, a double‐network eutectogel is fabricated by integrating polymerizable deep eutectic solvents (PDESs)including acrylamide/choline chloride/glycerol (acrylamide‐polymerization crosslink) thiolated hyaluronic acid (disulfide‐bonding crosslink). The introduction of PDESs provides with (up 0.25 S·m −1 ) strength (tensile strain 59–77%) simulating those natural human skin, well satisfactory tissue adhesiveness, self‐healing ability, antibacterial properties. When combined exogenous electrical stimulation, exhibits ability reduce inflammation, stimulate cell proliferation migration, promote collagen deposition angiogenesis, facilitate remodeling. This shows great potential dressing for healing major burn wounds.
