AB  - Asphaltene is often regarded as an undesirable by-product of petroleum 
      processing, possesses vast reserves with little market value. The typical routes 
      of consuming asphaltene, namely burning and landfilling, pose significant 
      environmental challenges. In this study, low-value asphaltene is converted into 
      high-value ethylated carbon clusters (ECC) using a supercritical ethanol 
      technique. The resulting ECC powder demonstrates promising properties for high 
      density polyethylene (HDPE) composite applications. The effects of incorporating 
      ECC on the mechanical, gas barrier, and anti-aging properties of the composite 
      are investigated. Results show that a 1 wt.% ECC led to a 4.2% and 43.5% increase 
      in tensile strength and elongation at break, a reduction of 45.8% and 30.7% in 
      oxygen and carbon dioxide permeability. Furthermore, ECC exhibits effective UV 
      spectrum absorption and conversion in the wavelength range of 400-600 nm, 
      providing protection against UV spectrum damage to HDPE. The incorporation of ECC 
      not only enhances the properties of polymer composites but also sequesters carbon 
      within the polymer matrix, enabling the valorization of asphaltene while 
      mitigating environmental impact.
