Synthesis and Properties of APTES Modified Fly Ash Floating Bead/Polyaniline

Keywords： fly ash floating bead , γ-amino propyl triethoxy silane , core/shell structure , polyaniline , composites

讨论了不同浓度γ-氨基丙基三乙氧基硅烷(APTES)甲苯溶液对粉煤灰漂珠(FAFB)硅烷化反应程度的影响,再以获得APTES修饰FAFB (FAFB-APTES)表面引入的氨基为反应点,与苯胺(An)发生聚合,制备出以FAFB-APTES为核、聚苯胺(PAn)为壳的核/壳结构复合材料(FAFB-APTES/PAn).采用化学元素分析、FTIR、XRD、SEM、TGA以及数字式四探针测试仪对复合材料结构及其性能进行分析.结果表明:APTES修饰FAFB的最佳修饰浓度为1.5 mol/L,且表面接枝率达到6.44％;SEM结果表明该种复合材料具有明显的核/壳结构;TGA分析可知引入FAFB后复合材料的热稳定性明显提高且PAn的包覆量达到28.2％;四探针技术分析可知复合材料FAFB-APTES/PAn的电导率达到5×l0-3S·cm-1,仍处于半导体的范围.
