Polymer–inorganic semiconducting composite (MCTP–Fe₃O₄) particles were fabricated by loading nanosized Fe₃O₄ on the microporous covalent triazine-based polymer (MCTP) through a chemical coprecipitation method and then applied to an electrorheological (ER) material. The structural and morphological images of MCTP–Fe₃O₄ composite were examined by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. Their magnetic property was also investigated by vibrating sample magnetometry. The chain structure formation of MCTP–Fe₃O₄ dispersed in silicone oil under an external electric field was confirmed using an optical microscope. The ER fluid based on MCTP–Fe₃O₄ was processed by dispersing the composite particles in an oil medium, and for comparison, an ER fluid based on pure MCTP was also prepared by the same process. The ER performance of two different ER fluids was scrutinized by a rotational rheometer, which demonstrated that MCTP–Fe₃O₄ showed better ER characteristics than MCTP-based ER suspension.

电响应性聚合物-无机半导体复合材料（MCTP-Fe ₃ O ₄）颗粒及其流变学

聚合物-无机半导体复合材料（MCTP -铁₃ ö ₄）颗粒被装载纳米的Fe制成₃ Ò ₄在微孔基三嗪的共价聚合物（MCTP）通过化学共沉淀法，然后施加到电流变（ER）材料。通过扫描电子显微镜，透射电子显微镜和X射线衍射检查了MCTP-Fe ₃ O ₄复合材料的结构和形态图像。还通过振动样品磁力分析法研究了它们的磁性。MCTP–Fe ₃ O ₄的链结构形成使用光学显微镜确认在外部电场下分散在硅油中。通过将复合颗粒分散在油介质中来处理基于MCTP–Fe ₃ O ₄的ER流体，为进行比较，还通过相同的方法制备了基于纯MCTP的ER流体。通过旋转流变仪仔细检查了两种不同的ER流体的ER性能，这表明MCTP–Fe ₃ O ₄表现出比基于MCTP的ER悬浮液更好的ER特性。
