AB  - Clogging generally happens to the leachate piping system, which poses a risk to 
      the environment. A low surface energy nanocomposite is prepared to mitigate the 
      cloggings, by adding the fluorinated acrylate polymer and hydrophobically 
      modified nano-silica into high-density polyethylene (HDPE) substrate. The best 
      addition of the fluorinated acrylate polymer and the nano-silica is given as 15% 
      and 5%, to produce the composite with a low surface energy of 29.4 mJ/m(2). 
      Through the characterization of contact angle (CA), electrochemical corrosion, 
      scanning electron microscopy (SEM) with energy dispersive X-ray spectrometer 
      (EDS), atomic force microscope (AFM) and thermogravimetry (TG), the composite 
      shows low wettability, good corrosion resistance and thermal stability. The 
      surface hydrophobic property of the composite remains unchanged after being 
      immersed in an acidic (pH = 2) and an alkaline (pH = 12) solution, indicating 
      that the prepared composite has strong adaptability to the extreme environments. 
      In addition, the composite shows better anti-scaling performance than that of the 
      commercial high-density polyethylene (HDPE) and polyvinyl chloride (PVC) pipe 
      materials by application of a dispensing leachate immersion test. The results 
      provide insights into engineering practice for the design and manufacture of pipe 
      materials for leachate collection and transport.
