Synthesis of Poly(ethylene terephthalate) Reinforced with Zinc Oxide Nanoparticles via Solution Blending for Prosthetic Socket Material: Physicochemical and Antibacterial Studies

High Resolution Image Download MS PowerPoint Slide This work synthesized recycled poly(ethylene terephthalate) (PET) with zinc oxide nanoparticles (1.0, 3.0, 5.0, and 7.0 wt %) via solution blending, aimed at transforming postconsumer plastic waste into high-value antibacterial materials for prosthetic socket applications. The PET/ZnO composites demonstrated homogeneous dispersion, improved mechanical hardness, and effective antibacterial activity, particularly at 7.0 wt % ZnO. Enhanced surface hydrophilicity and acceptable roughness were also observed. This approach improves prosthetic performance and promotes sustainable healthcare materials by utilizing plastic waste.
