Fabrication of biomimetic superhydrophobic surfaces inspired by lotus leaf and silver ragwort leaf

Jinyou Lin, Yu Cai, Xianfeng Wang, Bin Ding, Jianyong Yu and Moran Wang

Nanoscale, 2011, DOI: 10.1039/C0NR00812E, Paper

Inspired by the self-cleaning lotus leaf and silver ragwort leaf, the authors demonstrate the fabrication of biomimetic superhydrophobic fibrous mats via electrospinning polystyrene (PS) solution in the presence of silica nanoparticles. The  fibers they obtain present a fascinating structure with the combination of nano-protrusions and numerous grooves due to the rapid phase separation in electrospinning. The content of silica nanoparticles incorporated into the fibers proves to be the key factor affecting the fiber surface morphology and hydrophobicity. Read more
