摘要: A novel core–shell-type electrorheological (ER) composite material was fabricated via using polyaniline as an insulating layer to the outer surface of core conductive metal–organic framework (MIL-125) with controlled size and morphology. MIL-125 firstly synthesized by a solvothermal method, then in polar solvent tight coating successfully achieved form MIL-125@PANI core–shell nanocomposite. This structure greatly enhances polarization ability dispersed particles, thereby improving their rheological properties. The morphology pure has been characterized transmission electron microscopy (TEM) scanning (SEM). Their X-ray powder diffraction. Moreover, ER activity MIL-125-based MIL-125@PANI-based fluids dispersing particles into silicone oil studied rotational rheometer. results show that have higher
