Preparation and characterization of polystyrene-based monolith with ordered macroporous structure

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~...

Description
Summary: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.
