They are both also classified asthermoplastics. Thermoplastics are polymers that can be melted and recast over and over again, retaining all of their core qualities. Plastics like polyethylene and polypropylene are not only easy to fabricate and cost-effective, but are also highly recyclable. Their ...

The solid superacid-catalyzed depolymerization−liquefaction (DL) reactions of high-density polyethylene (HDPE), isotactic polypropylene (PPR), and cis-polybutadiene (PB) samples were systematically investigated as a function of processing conditions, i.e., temperature (350−450 °C), time (0.5...
We then proceeded to remove high-density polyethylene and polypropylene microplastics from water by introducing oil at the microplastics-water interface, and we determined the removal efficiency of the modified cotton fabrics. Findings After achieving a superhydrophobic non-woven cotton fabric (159 ± 1...
