摘　　要：在乙胺、丁胺和四丁基氢氧化铵剥离的α-磷酸锆(α-ZrP)中原位聚合苯胺(An),以过硫酸铵(APS)为氧化剂,在酸性介质中合成磷酸锆/聚苯胺(PANi)复合材料.用红外(FT-IR)、X-射线衍射(XRD)、四探针电导率仪、扫描电镜(SEM)对复合材料的结构和性能进行了研究,结果表明:剥离后的α-ZrP与PANi之间存在着一定的相互作用,不同剥离剂对α-ZrP/PANi复合材料的结构和电导率有明显的影响,剥离α-ZrP的层间距越大,越有助于电子在聚苯胺颗粒间的传导而使复合材料的电导率提高.During the process of in situ polymerization of Ani in the exfoliated α-zirconium phosphate, ethylamine, butylamine and tetrabutyl oxyammonia （TBA ^＋ OH^- ） were used to exfoliate α-ZrP, and ammonium ＇persulfate （APS） was oxidant. The composites of α-zirconium phosphate/polyaniline （α-ZrP/PANi） were synthesized in acidic aqueous solution. The structures and properties were studied by fourier transform infrared （FT-IR） spectra, X-ray diffraction （XRD）, the standard four probe technique, and scanning electron microscopy （SEM）. All of the results show that strong interactions exist between exfoliated α-ZrP and PANi molecule. Comparing with non-exfoliation α-ZrP/ PANi, their conductivity in- creased. With the different exfoliated agents loading, obvious variations on structures and conductivity of the composites were observed. Larger layer distance of exfoliated α-ZrP would result in improved conductivity of composites.
