| Abstract: |
| Polystyrene is one of the most popular plastic material. The modified polystyrene samples were exposed in outdoor at Lasa and Mohe natural environment test stations. The effects of natural environment on mechanics performance and weathering mechanism were studied by using ESEM and XPS. The impact strength of plastics sample has decreased by 41 percent after exposure test in Lasa natural environment test station for two years, and the apparent concentration (in atomic, Or/0 ) of oxygen was up t0 47.21%. |
