基于蒙脱石层间域二维纳米空间厚度的可扩展性,采用有机插层、单体引入及原位聚合法,制备了聚苯胺/蒙脱石纳米复合材料,利用XRD、FT-IR、TG-DSC、SEM和四探针电阻率测量仪等研究了复合材料的结构、热性能和导电性能,并讨论了复合机理。结果表明,当m(OM)/m(An)<0.3时,苯胺单体原位聚合后,蒙脱石晶层被充分剥离,复合材料的热稳定性提高;当有机蒙脱石与苯胺的质量比为0.09时,所制得纳米复合材料的电导率最大达到2.34S/cm。
Based on the scalability of two-dimensional nanoshells in the intergranular layer of montmorillonite, polyaniline / montmorillonite nanocomposites were prepared by organic intercalation, monomer introduction and in-situ polymerization. XRD, FT-IR, TG-DSC, SEM and four-probe resistivity meter were used to study the structure, thermal and electrical conductivity of the composites. The complex mechanism was also discussed. The results showed that when m (OM) / m (An) <0.3, the montmorillonite layer was fully stripped after in situ polymerization of aniline monomer, and the thermal stability of the composites increased. When the molar ratio of organic montmorillonite to aniline The mass ratio of 0.09, the conductivity of the obtained nanocomposites up to 2.34S / cm.
