原位合成纳米银/液晶复合材料及其表征

Synthesis and Characterization of nano Ag/liquid crystals composite material via the in-situ synthesized method

摘要:

针对纳米粒子易团聚的问题，采用原位合成法，以草酸银（Ag2C2O4）为原料，在热致液晶中原位热分解，制备出了纳米银/液晶复合材料。经X-射线衍射仪（XRD）、透射电镜（TEM）、X-光电子能谱仪（XPS）等表征，制得的纳米银粒径小于20纳米，在液晶中均匀分散，没有团聚现象。

Abstract:

To solve the problem of nanoparticles’ aggregation,the nano Ag/liquid crystals hybrid composite were prepared via in-situ synthesis method by thermo-decomposing Ag2C2O4 in thermotropic liquid crystals.The obtained composite of nano Ag/liquid crystals were characterized with X-ray diffraction (XRD),transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy(XPS).The results showed that the particle sizes of Ag were less than 20nm,which were mono-dispersed in liquid crystal, and no aggregation was observed.
