AB  - A superhydrophobic polymeric surface was prepared through a very simple bulk 
      photografting method. A thin layer of acrylic acid (AA), a highly hydrophilic 
      monomer, was sandwiched between two high-density polyethylene (HDPE) sheets, 
      followed by UV irradiation for a short time, and then the two sheets were pulled 
      apart and dried. The contact angles on the two grafted surfaces decreased very 
      quickly with irradiation time in the first several seconds, and then increased 
      with irradiation time to a level higher than that on pristine HDPE surface. When 
      using a scraped PE surface as the bottom one, it showed superhydrophobicity after 
      35 s irradiation. XPS investigations show that strong rearrangement of the 
      poly(acrylic acid) molecules has taken place on both surfaces, especially on the 
      bottom surface, which provides the low surface free energy. The scraping and the 
      grafting process led to the formation a unique micro- and nanostructure on the 
      surface. These two factors lead to the superhydrophobicity. The as-prepared 
      surface possesses superhydrophobic properties in a wide range of pH values, 
      stimuli-responsive properties and low or very high adhesion under different 
      situations.
