聚电解质原位生长CuS纳米粒子分子沉积膜的制备及表征
Synthesis and Characterization of In-situ Growth CuS Nanoparticles in Polyelectrolyte Molecular Deposition Films
摘 要
采用分子沉积技术制备了基础聚二烯丙基二甲基氯化铵/聚丙烯酸分子沉积(MD)膜,然后在基础MD膜中原位反应生长了CuS粒子;利用紫外-可见分光光度计、X射线光电子能谱仪及原子力显微镜对此膜进行了表征.结果表明:在膜中原位生长的CuS颗粒为纳米粒子,且纳米粒子在膜中分布均匀,无明显团聚现象;随着反应时间的增加,纳米粒子的粒径明显增大;随着循环反应次数的增加,除纳米粒子的粒径略有增大外,纳米粒子的数量也明显增多.

Abstract
The basal PDDA/PAA polyelectrolyte molecular deposition (MD) films were prepared first,and then CuS particles grew in the polyelectrolyte MD films in-situ.The films were characterized by ultraviolet-visible spectroscopy,XPS and atom force microscopy (AFM).The results show that the particles grown in the polyelectrolyte MD films were nano-sized CuS.The nanoparticles were distributed uniformly in the films and the agglomeration of nanoparticles was not obvious.The particle size increased apparently with the increase of synthesis time.And with the increase of synthesis cycle numbers,the particle size and the particle amount both increased.
