Claim:
1. A method for manufacturing a thermal ground plane, the method comprising: providing a first planar substrate member, wherein the first planar substrate structure is flexible, and wherein the first planar substrate member comprises either or both a metal layer and a polymer layer; disposing a liquid channel on the first planar substrate member using photolithography; disposing a mesh structure on either or both the first planar substrate member and the liquid channel, wherein the mesh structure is flexible; applying a coating to the mesh structure, wherein the coating creates corrosion protection for the mesh structure; disposing a vapor core on at least one of the first planar substrate member, the liquid channel, and the mesh structure, such that the mesh structure separates the liquid channel from the vapor core; disposing a second planar substrate member on the first planar substrate member such that the second planar substrate member and the first planar substrate member enclose the liquid channel, the mesh structure, and the vapor core, wherein the second planar substrate structure is flexible, and wherein the second planar substrate member comprises either or both a metal layer and a polymer layer; sealing at least a portion of the first planar substrate member with a portion of the second planar substrate member; charging the thermal ground plane with a working fluid via a fill tube; and sealing the fill tube, wherein the working fluid is fully enclosed within the thermal ground plane; wherein the thermal ground plane has a thickness less than 1 mm.
