| Abstract: | The amount of residual solvent in polymer blend membrane has a close relationship with the drying process,which influences the performance of the coating film.The drying process of polystyrene(PS)/polycarbonate(PC) blend solution in dichloromethane was investigated by using the quartz crystal microbalance(QCM) and self-made forced air convection drying device,where the blending ratio,hot airflow speed and temperature were varied.The experimental results were correlated by a creep transport model.The correla... |
