Ring-opening polymerization of ε-caprolactone (ε-CL) on the surface of hydroxylated biaxially oriented polypropylene (BOPP) film was initiated by aluminum isopropoxide in a sequential two-step method and in a one-step method. Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS)，and contact angle measurements confirmed that the grafting reaction occurred successfully in both cases, and that the one-step method was more effective than the sequential two-step method. SEM results show that a flat surface with a grafted layer covering could be obtained by the one-step method, whilst a surface with a distribution of small particles was obtained by the two-step method.
