Recently, many reports show that highly stretchable circuits can be designed using conductive composites which show good conductivity at tens of strain range. Conductive fillers used in these systems are Ag NP, Ag NW and Au Ns. Rubbery block copolymers combined with these conductive materials retains metal networks so that helps conductivity to be preserved at large strains. Up to date, nanoscale mechanisms by direct observation in this aspect have not yet reported so far. So the fundamental origin of conductivity changes of conductive composite during highly strained range or numerous cycle test remains unsolved. But this aspect has been neglected in this field although this is one of the major factors maintaining nanomaterial networks and conductivity against the fracture. In this sense, we will discuss mechanodynamics of electrode materials network during deformation by in situ tensile experiment to complement undiscovered part of the percolation theory. |
