Abstract
A wellbore isolation device comprising: a nanolaminate, wherein the nanolaminate comprises two or more layers of a first material and two or more layers of a second material, wherein the first material and the second material form a galvanic couple, and wherein the first material is the anode and the second material is the cathode of the galvanic couple. A method of removing the wellbore isolation device comprises: contacting or allowing the wellbore isolation device to come in contact with an electrolyte; and causing or allowing at least a portion of the two or more layers of the first material to dissolve.
