摘要

不同形态的氧化铝(Al2O3)由于其在催化、电池、太阳能转换、气体传感和场发射等技术领域的潜在应用而受到人们的极大关注。本文以乙二醇(EG)为分散剂和生长导向剂，采用固相法制备了纳米Al2O3。通过将这些纳米颗粒分散在乙二醇中获得纳米流体。采用特殊设计的带有两个不锈钢圆柱形电极的电池，在40 Hz和100 kHz的频率范围内测量了所得纳米流体的介电性能。al2o3基纳米流体的电导和电容随质量分数的增加而增大，且始终高于纯EG。

Dielectric properties of Alumina based nanofluids

The alumina (Al2O3) with different morphologies have great interest due to their potential use in various technological areas such as as-catalysis, batteries, solar energy conversion, gas sensing and field emission. In this work, nanostructured Al2O3 were prepared by a solution-phase method in the presence of ethylene glycol (EG) as a dispersant and growth-directing agent. Nanofluids were obtained by dispersing controlled amounts of these nanoparticles in ethylene glycol. The dielectric properties of the obtained nanofluids were measured in the frequency range 40 Hz and 100 kHz using a specially designed cell with two stainless steel cylindrical electrodes. The conductance and the capacitance of Al2O3-based nanofluid increase with the mass fraction and always stay higher than that of pure EG.
