实验研究了超声波分散时间、氨水的用量、脂肪酸链长及分散剂用量对所制备的磁流体的性质的影响。
1·Two water-based ferrofluids were prepared with peptization technique using dodecylamine and dodecanoic acid as dispersing agent.
以十二烷基胺和十二酸为分散剂，通过胶溶技术制备了两种水性铁磁流体。
2·The experimental results indicate that the surface tension of ferrofluids decreases with increasing temperature.
实验结果表明：铁磁流体的表面张力随温度的升高而减小。
