摘　　要：光敏热成像（PTG）材料是近几年得到迅速发展的一种新型信息记录材料。与传统卤化银成像材料相比具有设计独特、加工方法简便、无污染、能耗低、影像质量高等优点。已广泛应用于医疗成像领域，而且在高质量数据传真、航天拍摄、油田试掘记录等方面具有巨大的潜在应用价值。A new type of fibrous silver stearate （AgSt） was synthesized using double-jet method with KOH as pH regulator in water solution system. The structure, morphology and phase transiton behavior of the fibrous AgSt were characterized by FTIR, SEM, XRD and TG-DTA. SEM images showed that the diameter of the fibrous AgSt was about 150 nm and the length was 5-8 μm. XRD data indicated its layered structure and TG-DTA showed its high themal stability. In addition, the possible growth mechanism of the fibrous AgSt is also discussed.
