摘要
Acicular alpha-Fe nanoparticles were prepared by sodium borohydride reduction of ferrous chloride in the presence of the liquid crystalline system, C(12)EO(4)/water. The shape of the acicular particles was templated by the colloid and a magnetic field. The acicular particles obtained from the lamellar phase were 50 similar to 150 nanometers long and 5 nanometers wide. The product also included some spherical particles of 10 similar to 15 nanometers in diameter. The saturation magnetization was 94 emu/g and the coercivity was 420 Oe.
