In this study, hollow poly (O-phenylenediamine-co-O-toluidine) (POPD-co-OT) was synthesized via oxidative polymerization reaction. The POPD-co-OT was decorated into polystyrene surface core spherical particles before removing the core to obtain the hollow particles. The chemical structure and morphology of the conducting POPD-co-OT were studied with FTIR spectroscopy, proton NMR, scanning electron microscopy, and TEM. The hollow particles were applied in the dispersion phase for the preparation of electrorheological fluid (ERF). The rheological properties were investigated with a rotational rheometer, whereas the chain formation inside the ERF was observed using OM. The experimental results indicated that the shear stress of ERF increased with increasing strength of the electric field and quickly responded by impacting the external electric field strength. The ERF system is quite stable for a long time up to 200 h.

在这项研究中，中空聚（O-苯二胺-co-O-甲苯胺）（POPD-co-OT）是通过氧化聚合反应合成的。在除去芯以获得空心颗粒之前，将POPD-co-OT装饰成聚苯乙烯表面芯球形颗粒。用FTIR光谱，质子NMR，扫描电子显微镜和TEM研究了导电的POPD-co-OT的化学结构和形态。将中空颗粒施加在分散相中以制备电流变流体（ERF）。用旋转流变仪研究流变性质，而使用OM观察ERF内部的链形成。实验结果表明，ERF的剪切应力随着电场强度的增加而增加，并通过影响外部电场强度而迅速响应。ERF系统在长达200小时的长时间内都非常稳定。
