(Phys.org) —Using an ink containing tiny graphene flakes, scientists have inkjet-printed graphene patterns that can be used for printing finely detailed, highly conductive electrodes. Although inkjet-printed graphene has been previously demonstrated, the graphene patterns printed in the new study are about 250 times more conductive than previous patterns. The printed graphene ink is also highly tolerant to bending stresses, with the ability to withstand folding with only a slight decrease in conductivity.
