Photo-mechanical synergy in plastic weathering: UV aging accelerates shear-driven nanoparticle release in water
{{output}}
This study examined the shear-driven fragmentation of the UV-aged (UV-A: 340 nm; 0.91 W·m-2 over 16 weeks; dose = 8.81 × 103 kJ·m-2) and unaged polyethylene microspheres (180-212 μm) in water. Scanning electron microscopy revealed that UV aging and shear m... ...
