碳酸钙/镍复合材料的原位合成及其抗静电性能

In Situ Preparation and Antistatic Research of Calcium Carbonate/Nickel Composite

利用胶棉膜作为活性模板,制备出方解石型碳酸钙组装球,在其表面上将镍进行原位还原反应,首次成功获得了碳酸钙/镍复合导电材料,通过TEM、XRD、FT-IR和TG-DTA等测试技术对产物结构及性能进行了表征,并将产物应用于抗静电领域,制备成的抗静电涂料与用纯镍粉制备的涂料具有同等抗静电性能(电阻率为1.2×106Ω.cm),并可以节省60%的镍。该复合材料在导电和抗静电等领域具有应用前景,能够节省对镍的消耗。

Calcium carbonate（CC） with calcite structure was efficiently synthesized using collodion membrane as an active template.Then,the CaCO3/Ni composite was obtained through in situ reaction on the CC surface.The morphologies,structures,and thermal stability of the composite were studied by TEM,XRD,FT-IR and TG-DTA,etc.The composite was added to the antistatic-coating system,which shows the same antistatic ability（electrical resitivity：1.2×106 Ω·cm） as that of Ni powders,and saves about 60% Ni.The composite can be applied in the fields of conductive,antistatic,etc.,to replace Ni materials.
