Abstract
Polybutylene adipatecoterephthalate PBAT films were prepared using 4 different preparation methods and the effects of the processing method on physical mechanical and structural properties of PBAT films were studied Films were characterized using UVvisible spectroscopy FTIR XRD and thermogravimetric analysis All films were white in color and exhibited high UVbarrier properties Films prepared using solvent casting SC were less transparent than other films No structural changed were observed among PBAT films but films prepared at high temperatures exhibited a higher degree of crystallinity Extrusioncast EC films exhibited highest tensile strength values while solventcast SC films had the lowest TS values The water vapor permeability and water contact angle were not affected by the processing method The degree of crystallinity of EC films was higher than for other films
