Daftar Isi:
- Synthesis study ofmagnetic nanospheres involving wetting, emulsification using sonication and evaporation process have been done. Sonications time were varied for 3 minutes, 4 minutes, 5 minutes, 6 minutes and 7 minutes. Phase analysis result by X-Ray Diffractometer (XRD) showed that Poly Lactic Acid (PLA) tend to change to amorphous phase which become more significant with sonication time. There was no ferrofluid phase change. Size distribution analysis using Scanning Electron Microscope (SEM) showed for longer sonication time, size of nanospherewere decreasing and becomemore homogeneous. Hysteresis curve from measurement using Vibration Sample Magnetometer (VSM) showed increasing of magnetization value with decreasing of nanosphere size, which analized due to higher loading factor of ferrofluid within nanosphere. From these three characterization results, it can be concluded that sample with sonication time of 4 minutes give an optimum nanosphere with respect to its size, homogeneity and the magnetic properties.Keywords: Magnetic nanosphere, Ferrofluid, Poly Lactic Acid, Sonication.
