In this paper,polystyrene-based monoliths with highly ordered macroporous structure were synthesized by using SiO_2 colloidal crystal as template.SEM observation shows that the macropores are highly ordered and are interconnected by small windows.The BET surface area of PS monolith is about 36.17 m~2/g.The polymer monoliths can resist 5 MPa pressure,showing high mechanical and compressive strength. In this paper, polystyrene-based monoliths with highly ordered macroporous structure were synthesized by using SiO 2 colloidal crystal as template. SEM observations shows that the macropores are highly ordered and are interconnected by small windows. The BET surface area of ​​PS monolith is about 36.17 m ~ 2 / g. The polymer monoliths can resist 5 MPa pressure, showing high mechanical and compressive strength.
