• نبذة عن البـراءة

  Polypropylene (PP) superhydrophobic sheets and a fabrication method using a stream of polypropylene from plastic waste thereof are provided. Superhydrophobic PP sheets of varying thickness, having a base layer and a top layer, may be fabricated using recycled or waste polypropylene, where the fabrication process uses 20% of total plastic waste to prepare said sheets, having contact angles ranging from 140 to 160 degrees. The polypropylene superhydrophobic sheets may impart protective water-repellent properties against the elements.
