树形分子键合剂包覆AP及其相互作用研究

Study on Interaction between AP and Dendritic Bonding Agent

运用扫描电镜(SEM),X射线光电子能谱(XPS)和显微红外光谱(MIR)技术研究了树形分子键合剂(DBA)对AP晶体的包覆性能及其界面相互作用机理。实验表明,树形分子键合剂可以在高氯酸铵(AP)表面形成一层吸附层,具有良好的包覆性能,显微红外光谱的数据也表明键合剂与AP的N—H基团形成了氢键,从而证实了DBA作为AP键合剂的有效性。

A dendritic bonding agent (DBA) that can coat ammonium perchlorate (AP) filler successfully is reported. The coating properties are characterized by scanning electronic microscope (SEM), X-ray photoelectron spectroscopy (XPS) and Micro-infrared. DBA forms a viscous film on the surface of AP; the coating degree can be up to 47% from XPS analysis, the coating degree increases by increasing of CN group content. Micro-infrared analysis indicates that H-bond is formed between DBA and N—H groups, and it proves that DBA is available for coating AP.
