【Abstract】 The surface of polymer is direct exposure to environment, as a focus of weathering and weather resistance. The effect of weather on polymer surfaces are systematically reviewed in this paper. The applications of modern detecting techniques are evaluated in studying the phenomena and mechanism of weathering of polymer surfaces. It is emphasized that the modification of polymer surfaces is important to improve the weather resistance of polymer.更多还原
