以硅烷偶联剂为改性剂,在气流粉碎机中对纳米氧化锌进行解团聚和表面改性,并借助SEM、XRD、FT-IR对改性前后的纳米氧化锌粉体进行结构表征。结果表明,与改性前相比,改性纳米氧化锌的二次粒径明显减小,解团聚效果明显;颗粒表面亲油疏水,在有机溶剂中有较好的分散性。

Industrial ZnO nanoparticles were modified with silane coupling agent by the integrated process of jet grinding and surface modification using fluidized-bed jet mill by batch operation.The deagglomeration and surface modification of ZnO nanoparticles were investigated.The products were characterized by SEM,XRD and FT-IR,etc.The results showed that the agglomeration of modified ZnO nanoparticles was reduced severely and the twice particles size became smaller compared with initial ZnO nanoparticles.In addition,modified ZnO nanoparticles had much better dispersibility in organic solvents due to the lipophilic and hydrophobic groups on the surface of ZnO nanoparticles.
