1. A method comprising:
(a) selecting a first substrate having a first laser-induce material disposed on a first side of the first substrate, wherein
(i) the first substrate is a first graphene precursor material that can be formed in to the first laser-induced material, and
(ii) the first laser-induced material is selected from a group consisting of laser-induced graphene (LIG), laser-induced graphene scrolls (LIGS) materials, and combinations thereof (LIG/LIGS);
(b) selecting a second substrate having a first side and a second side, wherein
(i) the second substrate is a second graphene precursor material that can be formed in to a second laser-induced material, and
(ii) the second laser-induced material is selected from a group consisting of LIG, LIGS, and LIG/LIGS;
(c) contacting the first laser-induced material on the first side of the first substrate with the first side of the second substrate; and
(d) exposing the second side of the second substrate to a first laser source to form a layer of the second laser-induced material upon the first laser-induced material.
