Soft　nano　electronic　materials　based　on　conductive　hydrogels　have　attracted　considerable　attention　due　to　their　exceptional　properties.　Particle　deposition　and　poor　interface　compatibility　often　diminish　the　mechanical　strength　and　electron　transport　capabilities　of　the　conductive　hydrogel.　Mechanical　damage　can　severely　impact　the　performance　of　the　conductive　hydrogel　and　can　even　damage　electronic　devices　based　on　the　conductive　hydrogel.　In　the　current　study,　a　transparent　nano-silica　hydrogel　is　prepared　by　employing　an　extremely　easy-to-operate　method.　This　approach　can　preclude　the　deposition　of　particles　via　strong　mechanical　force.　In　addition,　controlling　the　concentration　of　the　reaction　interface　makes　the　hydrogel　grow　along　the　mechanical　force　in　the　direction　with　a　special　directional　hole　structure　formed.　The　hydrogel　is　transparent,　showing　excellent　self-healing　properties-it　can　self-heal　within　15　seconds.　Remarkably,　the　hydrogel　after　self-healing　maintains　its　performance.　Moreover,　it　has　excellent　mechanical　properties　and　can　be　stretched　in　length.　Up　to　1,200　%　of　the　original　length,　the　tensile　strength　of　the　gel　spline　can　reach　7　MPa.　The　viscosity　of　the　hydrogel　can　reach　1.67　x　10(8)　(MPs).　In　addition,　a　large　amount　of　Na+　in　this　hydrogel　endow　it　a　conductivity　of　389　mu　s/cm.　The　conductivity　of　this　hydrogel　is　adjustable　result　from　the　special　pore　structure.　Lastly,　the　difference　between　the　horizontal　and　vertical　conductivity　of　the　same　sample　can　reach　3-4　times,　thus　this　hydrogel　can　be　used　in　the　field　of　nano　conductive　materials.
