摘　　要：通过三聚氰胺(MEL)与植酸(PA)制备植酸铵(MEL-PA),并将其负载于层状二硫化钼(MoS_(2))表面,获得植酸铵包覆二硫化钼(MEL-PA@MoS_(2))杂化结构。分析了MEL-PA及MEL-PA@MoS_(2)的元素组成、结构形貌及热稳定性能。结果表明:经MEL-PA包覆改性后MoS_(2)表现出了-C=H-,P=O与P—O的特征吸收峰,MoS_(2)粒子表面出现了C、N、O、P等元素,且随着MEL-PA添加量的增加,MEL-PA@MoS_(2)表面的微粒物越显著,表面越粗糙,相应的元素含量也随之上升,上述结果表明,MEL-PA成功负载于改性后的MoS_(2)表面。Ammonium phytate(MEL-PA)was prepared from melamine(MEL)and phytic acid(PA),and loaded on the surface of layered molybdenum disulfide(MoS_(2))to obtain ammonium phytate coated molybdenum disulfide(MEL-PA@MoS_(2))hybrid structure.The elemental composition,structural morphology and thermal stability of MEL-PA and MEL-PA@MoS_(2)were analyzed.The results show that MoS_(2)after coating with MEL-PA appeares the characteristic absorption peaks of—C=N—,P=O and P—O.The element of C,N,O,P appears on the surface of MEL-PA@MoS_(2).With the increase of MEL-PA contents,more particulate matter appears on the surface of the MEL-PA@MoS_(2),and the surface also becomes rougher.The above results indicate that MEL-PA is successfully loaded on the modified MoS_(2)surface.
