添加表面活性剂是提高电流变液电流变效应的有效方法。然而,传统的制备方法制备表面活性剂改性的二氧化钛颗粒是复杂的。采用静电喷雾法制备了聚乙烯吡咯烷酮(PVP)修饰的二氧化钛纳米粒子。实验研究了PVP浓度、喷射速率和电喷雾场对粒子尺寸和形貌的影响。分别用水解法制备的TiO 2/PVP粒子和裸TiO 2粒子制备电流变液。TiO 2/PVP复合粒子具有单分散性和核壳结构。与TiO 2粒子基样品相比,TiO 2/PVP粒子基电流变液具有更显著的电流变性能、更稳定的剪切稳定性和更好的沉降稳定性。静电喷涂法具有大规模生产高性能电流变液的潜力。
ABSTRACT Adding surfactants is an effective method to promote the electrorheological (ER) effect of ER fluids. However, conventional fabrication method to prepare surfactants modified titanium oxide particles was complex. In this study, a facile electrostatic spraying (ES) method was used to prepare polyvinylpyrrolidone (PVP) modified TiO2 particles. The influence of PVP concentration, ejection rate, and ES field on particle size and morphology was investigated experimentally. ER fluids were fabricated with the TiO2/PVP particles and the bare TiO2 particles obtained by a hydrolysis method, respectively. The TiO2/PVP particles have monodispersed size and present core-shell structure. Compared with the TiO2 particles-based sample, the TiO2/PVP particles-based ER fluid presents more significant ER performance, more stable shear stability, and better sedimentation stability. The electrostatic spraying method has the potential for large-scale production of high-performance ER fluids.
