For example, no any change was observed when the irradiated film was immersed in DMF at 20 ℃ for 12 h, but the unirradiated film was destroyled completely when it was immersed in DMF at the same temperature for 20 min. The dramatically improvement for the stability of the film towards polar solvents should be attributed to the bond conversion of the layers from H bond to covalent bond under UV irradiation.展开更多
