What is currently known as the thinnest combination of material to hold 1 atm in space?

Note: must define what the composing materials are.

  • $\begingroup$ Ignore debris in LEO as well? It's best to explain things like that in the question itself since sometimes people don't read the comments. $\endgroup$

    $\begingroup$ Since the question is tagged [spacesuits], are we to assume that you want answers limited to that? $\endgroup$

    $\begingroup$ A spacesuit with a pressure of 1 bar in vacuum is useless anyway. The poor astronaut would not be able to move his arms and legs against the forces resulting from the high pressure. Spacesuits are used with a much lower pressure, about 0.3 bar. $\endgroup$

    $\begingroup$ The size and shape are important. A glass microballoon has a wall thickness in the tens of nanometers and would have no trouble holding 1 atm. Not a suitable material for spacesuits though. $\endgroup$ Commented Nov 15, 2018 at 19:54
