NOVELTY - Preparing stretchable graphene electrode material involves keeping graphene material in a vacuum reaction furnace heating area at 100-500 degrees C for 10-30 minutes and then annealing the heated material. The annealed material is heated at 900-1100 degrees C and then the heated material is added with carbon source. The obtained material is subjected to perform growing process for 5-180 minutes and then the obtained material is cooled to room temperature to obtain substrate. The graphene is deposited on the substrate and the obtained material is soaked in etching solution. USE - Method for preparing stretchable graphene electrode material (claimed). ADVANTAGE - The method enables to prepare stretchable graphene electrode material in cost-effective and controllable manner, with high conductivity. DETAILED DESCRIPTION - Preparing stretchable graphene electrode material involves keeping graphene material in a vacuum reaction furnace heating area at 100-500 degrees C for 10-30 minutes and then annealing the heated material. The annealed material is heated at 900-1100 degrees C and then the heated material is added with carbon source. The obtained material is subjected to perform growing process for 5-180 minutes and then the obtained material is cooled to room temperature to obtain substrate. The graphene is deposited on the substrate and the obtained material is soaked in etching solution. The obtained sponge graphene-metal particle mixed structure is cleaned with acetone, ethyl alcohol and deionized water. The stretchable elastic adhesive is applied on substrate and then the obtained material is dried. The prestretched elastic substrate is stretched slowly to recover its original length or area and to obtain the desired product.
