OBJECTIVE: To Prepare and characterize polybutylcyanoacrylate (PBCA) magnetic nanoparticles.
METHODS: The suspension of PBCA magnetic nanoparticles was prepared by emulsion polymerization method. The particle size, size distribution, polydispersity and other parameters were determined by photon correlation spectroscopy and transmission electron microscopy, and the iron content in the nanoparticles by ultraviolet spectroscopy.
RESULTS: The data of the particle size and size distribution of aqueous decanoic acid stabilized Fe3O4 magnetic fluids were acquired, and the influences of concentrations of butylcyanoacrylate (BCA) and Dextran-70 on the particle size and size distribution of PBCA magnetic nanoparticles were characterized.
CONCLUSION: We have for the first time successfully prepared stable suspension of PBCA magnetic nanoparticles by emulsion polymerization method at pH 6.3-6.4 in aqueous medium.
