Applications of PDMS-COO-Zn polymer. a, b Various of 3D objects printed from the PDMS-COO-Zn polymer. c The irregular objects obtained by 3D printing. d An electrical circuit based on the PDMS-COO-Zn/graphene composite could be printed on paper, and the as-prepared device can be reshaped. e The effect of cure time and temperature upon lap shear adhesion with the PDMS-COO-Zn/graphene composite as conducting adhesive. Error bars are the s.d. from triplicate measurements. f A circuit that glued and conducted by PDMS-COO-Zn/graphene composite could sustain a weight of 800 g
