摘　　要：Herein,self-assembled superhydrophobic composite coatings were successfully prepared using a one-step dip-coating method on different irregular parts.The fluorinated nano-SiO_(2) particles spread into a uniform layer owing to the viscosity of the composite resin.After the optimization of the process,the fabricated nanoporous-structured coating has low adhesion properties with chemical and high thermal stabilities.After baking at 250℃ for 2 h or soaking in a solution of pH=1 or pH=13 for 10 days,the coating could maintain its good superhydrophobicity.The self-ejecting effects of the condensed dewdrops and droplet bounce phenomenon indicate that the coatings can be well-distributed on components of different structures,and they have significant application prospects in irregular parts and industrial production in the near future.
