Ding, Z. Sun, W. Zhang, Y. Peng, A. S. C. Chan, P. Li]  The average diameter, diameter distribution and surface morphology of Fe3O4/poly(styrene-co-N-isopropylacrylamide)[P(St-NIPAM)] particles were characterized by scanning electron microscopy. The copolymer structure was confirmed by IR spectroscopy, differential scanning calorimetry and elemental analysis. The content of Fe3O4 entrapped in the particles was determined by atomic absorption spectrometry. A coarse structure was observed on the surface of the Fe3O4/P(St-NIPAM) particles. The hydrodynamic diameter of the Fe3O4/P(St-NIPAM) particles was found to exhibit about a 15% decrease in diameter on changing the temperature from 25 to 40 °C. The results also showed that Fe3O4/P(St-NIPAM) an advantage of exploited magnetic separation.
