compatibility, polycaprolactone, lovastatine, alginate, solution method


In this work, alginate (AG)/chitosan (CS)/lovastatine (LS) AG/CS/PCL/LS composite films using polycaprolactone (PCL)  are prepared by solution method with the ratio of AG/CS and LS content fixed at 4/1 and 10 wt.% (in comparison with the total weight of CS and AG), respectively.  The PCL content is used at 3, 5 and 10 wt.% (in compared with total weight of AG, CS and LS). The role of PCL as a compatibilizer in AG)/CS)/LS composites is considered by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM) and Differential Scanning Calorimetric (DSC) methods. Based on the change in FTIR spectra, morphology and thermal parameters of AG/CS/PCL/LS composites, it can be seen that PCL has effectiveness of compatibility for AG, CS, and LS as well as plasticity for the composites. Besides, the influence of PCL content on the swelling degree of the composites is also investigated.
