Chemical composition of the green polyethylene before and after 120 d of exposure to sunlight.
Fig 1.
FTIR spectrum of the green polyethylene before (G0duv) and after 120 d of exposure to sunlight (G120duv).
The bands: 3000–2500 cm-1 –Bond carbon-hydrogen (CH2 or CH3); 1500–1400 cm-1—Bond carbon-hydrogen (CH) and 800–700 cm-1—Bond carbon-carbon (C-C).

Scanning electron micrography of green polyethylene surface before (G0duv) and after 30 d (G30duv), 60 d (G60duv), 90 d (G90duv) or 120 d (G120duv) of exposure to sunlight.
Note the absence of any expressive modification in the plastic surface due to sunlight exposure.
