No, you could still do this with current-ish technology. The solar sail
would just be a large reflecting mirror, about 1 um thick (which implies
in-space film processing - perhaps take a heavy Mylar and then
chemically remove the polymer).

Can you vapor deposit Al on graphene?

next:
develop a process that creates wide, continuous graphene tape.
