摘要
通过反相细乳液聚合合成了含有硫酸镉(CdSO_4)的聚丙烯酰胺(PAM)乳胶粒子,并通过吸收硫化钠(Na_2S)细乳液制备了硫化镉-聚丙烯酰胺(CdS-PAM)纳米杂化粒子。研究了CdS-PAM杂化粒子形成过程中乳胶粒子吸收细乳液液滴吸收时间和温度的影响因素;考察了水合CdSO_4/Na_2S用量对乳胶粒子吸收液滴过程以及对CdS-PAM纳米杂化粒子的影响,并测定了CdS-PAM杂化粒子的光催化性能。结果表明:随着硫酸镉用量的增加,乳胶粒子吸收硫化钠细乳液液滴能力减弱。以0.100 g/0.094 g水合CdSO_4/Na_2S制备的CdS-PAM杂化粒子具有较好的光催化性能。至此,采用反相细乳液成功制备出了具有光降解性能的CdS-PAM纳米杂化粒子。
Cadmium sulfide-polyacrylamide(CdS-PAM)nano hybrid particles were prepared by absorbing miniemulsion droplets of sodium sulfide(Na2S)using PAM miniemulsion containing cadmium sulfate(CdSO4).Effects of absorption time,temperature and CdSO4/Na2S hydrate amounts on CdS-PAM hybrid particle formation were studied.The photocatalytic performance of the CdS-PAM hybrid particles was measured.The results show that latex particle absorption decreases with the increase of CdSO4 in PAM.The CdS-PAM hybrid particles prepared by CdSO4/Na2S mass ratio of 0.100 g/0.094 g show good photocatalytic properties.The results indicate that CdS-PAM nano hybrid particles with good photocatalytic properties are synthesized by inverse miniemulsion.
