Abstract

The aim of this study is to examine how gamma radiation affects the mechanical, physical, and morphological behaviours of ABS composite membranes Acrylonitrile Butadiene Styrene (ABS). The tensile strength and stiffness of pure ABS membranes increased at higher radiation doses (100 kGy) due to cross-linking, counteracting the severe ductility observed at lower doses. In contrast, the tensile strength of ABS-CuO composite membranes decreased with higher radiation. FTIR analysis revealed that gamma radiation altered the molecular structure of the membranes, affecting their infrared absorption and transmission. SEM imaging showed notable roughness and imperfections on the irradiated membranes. Overall, gamma radiation weakened the membranes, but with the right dosage could potentially provide benefits, especially in medical applications. The findings highlight the importance of carefully controlling radiation exposure to optimize the performance of ABS composite membranes.
