The present invention provides nanocomposite materials comprising carbon nanotubes and oligo(p-phenylenevinylene) (OPV). Dispersion of CNT in the solution of solution of oligo(p-phenylenevinylene) (OPV) in organic solvent results in the formation of nanocomposite material. The π-π interaction between CNT and OPV molecule were shown by spectroscopic and microscopic techniques. The nanocomposite solution can be drop casted over glass or metallic surface for the preparation of superhydrophobic coating. The resultant composite surface shows superhydrophobic nature even with corrosive liquids and its contact angle is almost constant even after prolonged contact with water.
