The steadily increasing interest in reducing industrial pollutants spurred by the growing world-wide energy demand has led to active research interest in biodegradable plastics. Nanoporous zeolites (NZs) were utilized to impart a biodegradable polymer film with superhydrophobicity, ethylene gas adsorption capability, and active antibacterial activity. Biodegradable polymer PBAT/PLA/PBS(87wt%/6.5wt%/6.5wt%) (PPP) were compounded using a twin-screw extruder. NZs were synthesized by using organic silanes vis a sol-gel method. They were then dispersed on a PPP film to enhance its mechanical properties and control water repellent. The film prepared by utilizing octadecyltriethoxysilane (ODTES) was superhydrophobic with a contact angle 142.6°. The porous structure of the PPP with attached ODTES-NZs impeded the release of accumulated charges generated through friction, yielding excellent antibacterial efficacy against externally introduced bacteria when the accumulated positive charges are provided.
