Abstract
In this study, we synthesized UV-curable acrylates with carboxylic acid groups as substrate for self-assembly processing in producing conductive polyaniline. The conductive pattern by self assembly techniques was developed. Develop the optimum produce process.
Acrylic acid was used as monomer to blend with urethane acrylates in order to synthesize the UV-curable acrylates with carboxylic acid. The pattern with 5~100μm line-width was prepared by lithography technique. The aniline monomer was self-assembled to the carboxylic acid groups on the pattern by the molecular attraction to form complex. The “in-situ polymerization” to polymerize PANi was conducted further in the aqueous solution.
We used FT-IR to identify the structure of resins. And used GPC to analyze their molecular weight. The morphology of patterns were observed by OM and AFM. UV-Vis spectroscopy & ESCA were employed to identify the self-assembly results of PANi. In thermal properties, TGA and DSC were used to analyze our samples. Finally, we use the four-probes method to measure the sheet resistivity and use the UV-Vis spectroscopy to analyze their transparency.
The transparent conducting membrane with conductivity about 10 S/cm and mean transparency over 70% was obtained. The performance of the transparent conductive membrane can be improved further for the commercial applications.
