Eraserhead: A reversible nanoporous antireflection coating can be fabricated by assembly of layered double hydroxide nanoparticles with polyanions using an electrostatic layer-by-layer method followed by calcination. Antireflection properties of the coating can be switched between the porous and non-porous state by alternating calcination and rehydration processes.
