Fabrication of high yield and highly crystalline poly(2,5-dimethoxyanline) nanoplates using various organic sulfonic acids as the dopant agents and soft-templates

This paper demonstrates a simple and effective approach to fabricate highly crystalline poly(2,5-dimethoxyaniline) (PDMA) nanoplates using various organic sulfonic acids including Dodecyl benzenesulfonic acid (DBSA), Camphorsulfonic acid (CSA) and p -Toluenesulfonic Acid ( p -TSA) as the dopant agents. The structures and morphologies of PDMA nanoplates were characterized using Fourier transform infrared spectrometer, Raman spectrometer, X-ray diffraction, Atom force microscope and Electron microscope. The results show that the PDMA nanoplates possess high crystallinity and layered nanoplate aggregation structure. The estimated degree of crystallinity is higher than 95 %. With different organic sulfonic acids used, the aggregation structures of PDMA nanoplates vary from triclinic hexahedron to cuboid and rod shape. Through adjusting the dopant agent/monomer molar ratio, the yield of PDMA nanoplates can be as high as 53 %.
