| 摘 要： | 为扩展夜光粉的应用领域,以不同碳链长度的饱和脂肪酸(辛酸、月桂酸、硬脂酸)为有机功能配体制备了3种新型铝锆偶联剂(CA),并对夜光粉(SrMgAl4O8:Eu2+、Dy3+)进行了表面修饰,用ATR-FTIR和接触角表征了样品表面性质,用水中pH和电导率的变化测定其耐水性,用TG表征了不同CA、原样及改性样的热失质量行为,并以此首次提出计算不同CA在夜光粉表面包覆量的方法及其结构模型。结果表明:随着CA中饱和脂肪酸碳链长度的增加(由辛酸到硬脂酸),夜光粉表面包覆量由13.41%降为6.53%,月桂酸基铝锆CA改性样具有最佳的耐水性和相容性。 |

| Abstract: | To expand the application of the long afterglow phosphors,three saturated fatty acid(caprylic,lauric and stearic acid) based Al-Zr coupling agent(CA) were synthesized,which were used to modify the phosphors SrMgAl4O8:Eu2+,Dy3+.ATR-FTIR and contact angle were used to characterize their surface behavior.The pH value and electric conductivity in water were determined to evaluate their water resistance.TG Analysis was performed to characterize the thermal weight loss behaviors of CA,oringinal and modified sampl... |
