Ultrathin poly­(lactic acid) (PLA) films have been prepared by a melt-draw technique, and their structures and mechanical properties have been studied by atomic force microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and tensile test. It is found that the melt-dr...
