And the PLA/Chitosan/ACP barriers with additional 2 wt% chitosan still maintain 56.58 % antibacterial ability after eightieth day. The different composition of PLA/Chitosan/ACP composites was prepared by water washing solidification from NMP/water/lactic acid consolvent. After storing at room temperature for 48 hours and taking it out to obtain a shapable composites. To investigate the influence of ratio of composition with the shapable property of composites, it was analyzed by Rheometer, TGA, AFM, XRD. The result of the different APC content had different effect both water content and yield stress of composite materials. The yield stress decreased with ACP content while increases. It was derived that ions, released from ACP interact with amide groups of chitosan to form water-absorbing ionic clusters through chelating or electrostatic attraction.
