摘要

采用分子筛负载CdCl

再与Na

S反应获得负载纳米CdS的分子筛M-CdS，将其与聚乙烯复合得到具有特殊光性能的材料PE/M-CdS。通过紫外可见吸收光谱、荧光光谱和DSC等对复合材料的光性能和结晶性能进行了表征。结果表明：PE/M-CdS复合材料在540~550 nm波长范围呈现明显的荧光发射现象，并且随着M-CdS含量增加，荧光发射峰略微红移，荧光强度先增强后减弱。紫外光谱显示复合材料在280~325 nm有明显的吸收峰，且随着M-CdS含量的增加而增强。M-CdS对PE具有异相成核作用，复合材料结晶温度提高。随M-CdS含量增加，PE结晶生长受阻，熔融热焓下降，结晶度降低。

Abstract

The zeolite loading nano-CdS particles (M-CdS) were prepared by situ-reaction between CdCl

absorbed in zeolite and Na

S solutions

and then were used to modify PE in order to get functional polymer composites. The optical properties and crystallization behavior were characterized by UV-Vis

PL and DSC analyses

respectively. The results showed that PE/M-CdS composites exhibited an obviously fluorescence emission in 540~550 nm

the emission shifted to longer wavelength and the intensity improve first

and then became weak with the increase of M-CdS contents. But the absorption strength between 280 nm and 325 nm in UV-Vis spectra of PE/M-CdS composites increased with the increment of M-CdS contents

at the same time the crystallization degree and melt enthalpy decrease. M-CdS showed the heterogeneous nucleation effect on PP/M-CdS composites

which displayed a higher crystallization temperature than PP.
