The CTS/PHBV blend films at various wt ratios (1:1, 2:1 and 3:1), as well as neat CTS and PHBV films were prepared from chitosan, PHBV and glacial acetic acid by solution blending, and thoroughly characterized by TG, FT-IR and XRD. The results show that the properties of the blend films are mainly influenced by PHBV during crystallization, while the crystal structure does not change at all. Increasing the CTS content can improve the thermal stability of the blend films. Moreover, studies on the swelling and hemolytic behaviors of all films confirm that the swelling ratio decreases with the increase of the PHBV content for the blend films. At an optimum CTS/PHBV ratio, the blend film can effectively improve the hemolytic performance, and reduce the damage to the blood cells.
