Preparation and Performance Evaluation of X-ray-Shielding Barium Sulfate Film for Medical Diagnosis Using PET Recycling and Multi-Carrier Principles

The use of disposable containers and packaging materials has increased due to the recent COVID-19 pandemic. Thus, generation plastic waste is also increasing, research on recycling such being actively conducted. In this study, an X-ray-shielding film for medical diagnosis was manufactured by mixing a radiation-shielding material waste-based polymer its effectiveness evaluated. film, which intended as fabric shielding garment, consists barium sulfate (BaSO4) nanoparticles embedded in matrix polyethylene terephthalate (PET), commonly available material. A particle-dispersing technology, can improve ratio between while maintaining tensile strength studied. Therefore, increase content used material, multi-carrier method—under particles are dispersed units time—was developed performance. Compared with lead (Pb) 3 mm study satisfies equivalent 0.150 mmPb when stacked two layers. successfully using resin sulfate, eco-friendly instead lead.
