Ph 70, 2012 FA Shiyi “Teresa” Liu
Lighter than air?
Six Times Lighter than air!
Introducing Aerographite • Jet-‐black, non-‐transparent • Stable • Electrically conductive • Ductile • Density: 0.2 mg/cm3
Film
Aerographite attracted by polymer rod
Electrical ConducBvity
Lattice structure in graphite
Density Comparison
Aerographite (0.2 mg/cm3)
Water (1000 mg/cm3)
