Electrorheological (ER) fluids generate mechanical responses to applied electric field strength via changing their rheological properties from liquid to solid and vice-versa reversibly. As a result of this, ER fluids can be used in the industrial vibration damping systems. In order to increase applicability of ER fluids, it is necessary to understand electric field induced polarization and ER mechanism of different materials. Therefore, the aim of this study is to illuminate ER and vibration damping properties of polyanthracene (PAT), which is a new material for ER studies. PAT was synthesized from anthracene and characterized by several techniques namely: ATR-FTIR spectroscopy, particle size, SEM image, four-point probe conductivity, and magnetic susceptibility measurements. A series of PAT/silicone oil (SO) dispersions having various concentrations were prepared and subjected to dielectric and ER tests. Then, the colloidal stabilities of 20% PAT/SO and 20% PAT/SO/TritonX systems were determined. Dynamic viscoelastic data obtained by the oscillation tests showed that viscous behavior was dominant under zero electric field, whereas elastic behavior was prevailing under external electric field strength and highlighting the vibration damping characteristics of PAT/SO dispersion. In the creep-recovery measurements, the highest %recovery was recorded to be 62% indicating potential industrial use of PAT/SO dispersion.

电流变 (ER) 流体通过将其流变特性从液体变为固体，反之亦然，从而对施加的电场强度产生机械响应。因此，ER 流体可用于工业减振系统。为了提高缓释流体的适用性，有必要了解不同材料的电场诱导极化和缓释机制。因此，本研究的目的是阐明聚蒽 (PAT) 的 ER 和减振性能，这是一种用于 ER 研究的新材料。PAT 由蒽合成，并通过多种技术表征：ATR-FTIR 光谱、粒径、SEM 图像、四点探针电导率和磁化率测量。制备了一系列具有不同浓度的 PAT/硅油 (SO) 分散体并进行介电和 ER 测试。然后，确定了 20% PAT/SO 和 20% PAT/SO/TritonX 系统的胶体稳定性。通过振荡试验获得的动态粘弹性数据表明，在零电场下粘性行为占主导地位，而在外部电场强度下，弹性行为占主导地位，突出了 PAT/SO 分散的振动阻尼特性。在蠕变恢复测量中，最高百分比恢复记录为 62%，表明 PAT/SO 分散体的潜在工业用途。通过振荡试验获得的动态粘弹性数据表明，在零电场下粘性行为占主导地位，而在外部电场强度下，弹性行为占主导地位，突出了 PAT/SO 分散的振动阻尼特性。在蠕变恢复测量中，最高百分比恢复记录为 62%，表明 PAT/SO 分散体的潜在工业用途。通过振荡试验获得的动态粘弹性数据表明，在零电场下粘性行为占主导地位，而在外部电场强度下，弹性行为占主导地位，突出了 PAT/SO 分散的振动阻尼特性。在蠕变恢复测量中，最高百分比恢复记录为 62%，表明 PAT/SO 分散体的潜在工业用途。
