Preparation method of magnetic orientation nickel-cobalt alloy-carbon fiber cement-based sensing material
The invention discloses a preparation method of a magnetic orientation nickel-cobalt alloy-carbon fiber cement-based sensing material. The preparation method comprises the following steps: dispersing carbon fibers and then carrying out roughening treatment; carrying out micro-crystallization treatment on the surface of the coarsened carbon fiber; carrying out chemical plating treatment on the carbon fibers subjected to the micro-crystallization treatment to prepare cobalt-nickel alloy plating-carbon fibers; and compounding the cobalt-nickel alloy-plated carbon fiber with cement, and preparing the magnetic orientation nickel-cobalt alloy-carbon fiber cement-based sensing material under the induction of a magnetic field. The microcrystallization process is introduced, sensitization and activation processes are not needed, the cost can be greatly saved, the chemical plating efficiency is improved, and impurity ion introduction is reduced. According to the magnetic orientation nickel-cobalt alloy-carbon fiber cement-based sensing material, the cobalt-nickel alloy-carbon fiber is prepared through chemical plating by taking the carbon fiber as a carrier, the contact angle of the surface-metallized carbon fiber is greatly reduced, and the surface-metallized carbon fiber can be fully wetted by water and is uniformly dispersed in a cement matrix, so that the magnetic orientation nickel-cobalt alloy-carbon fiber cement-based sensing material shows good mechanical properties and sensing properties.
本发明公开了一种磁定向镍钴合金‑碳纤维水泥基传感材料的制备方法，包括以下步骤：将碳纤维分散后进行粗化处理；对粗化处理后的碳纤维表面进行微晶化处理；将微晶化处理后的碳纤维进行化学镀处理，制得镀钴镍合金‑碳纤维；将镀钴镍合金‑碳纤维与水泥复合，在磁场诱导下，制得磁定向镍钴合金‑碳纤维水泥基传感材料。本发明引入微晶化过程，无需进行敏化活化过程，可大大节约成本，提高化学镀效率以及减少杂质离子引入。以碳纤维作为载体，通过化学镀制备得到钴镍合金‑碳纤维，表面金属化的碳纤维接触角大大降低，可以充分被水湿润并且均匀分散在水泥基体中，使磁定向镍钴合金‑碳纤维水泥基传感材料表现出良好的力学性能与感知性能。
