Paper, White hairy layer on the Boehmeria nivea leaf—inspiration for reflective coatings
Boehmeria nivea, a tropical and subtropical plant, has a highly reflective layer on the lower surface of the leaf. Researchers found that this layers contains numerous wrinkled micro-filaments that form a disordered porous network that efficiently scatters visible light. This layers was also found to be hydrophobic and reflect incident light when exposed to high radiation. In trying to reflect this leaf and it’s properties, researches fabricated a porous polymeric membrane to demonstrate light-shielding and light-management abilities.
