Abstract
AbstractThe increase of plastic waste in the marine environment raises several ecological, human, and biological problems. In this work, an accelerated artificial aging study was conducted in seawater after immersing samples of high‐density polyethylene bottles for several aging times and at three different temperatures. The deterioration of the mechanical properties of High density polyethylene (HDPE) under different aging conditions was investigated using tensile and compression tests. The absorption of seawater by the samples was analyzed using a gravimetric method and Fourier transform infrared spectrometry (FTIR). Further surface analysis of the samples during accelerated aging was performed using a scanning electron microscope. The results show that HDPE loses its ductility and rigidity. FTIR analysis confirms the increase in crystallinity during aging.
