Ordered porous polymer films via phase separation in humidity environment
چکیده انگلیسی
A transition of morphology from island-like structure to disordered and ordered holes on the surface of polystyrene (PS) and poly(2-vinylpyridine) (PVP) blend films were observed with the increase of humidity. At appropriate weight ratio of PS/PVP and PS molecular weight, when humidity reached to a critical value, the hexagonal arrays of holes formed for PS/PVP blend films due to 'breath figures' stabilized by PVP with its strong hygroscopic characteristics during phase separation.
