We study the effect of stirring duration on the synthesis of polyethylene glycolhydroxyapatite (PEG/HA) nanocomposites and their hardness and antibacterial characteristics. The HA was used from natural deposit calcite rock from Druju-Malang. In this study, PEG/HA composite with a composition ratio of 20:80 in %Wt was obtained through co-precipitation method with various stirring duration of 1, 2, 4, and 6 hrs. The results indicate that the variation of stirring duration of the PEG/HA composite promotes a change of functional bonds, grain size, and hardness value. The optimum hardness was achieved by stirring duration of 2 hrs. Furthermore, the PEG/HA composite exhibited a relatively consistent value of antibacterial zone in a variation of stirring duration, but it still showed an antibacterial performance. Our study would give a good understanding of the technique to improve mechanical and antibacterial properties in HA-based biomedical applications for bone regeneration. © Published under licence by IOP Publishing Ltd.
