Abstract

Diacetylene (DA) is an amphiphilic structure and has been studied as a variety of PDA-based chemosensors. However, the prospect of using diacetylene (DA) as dopant of polyaniline (PANI) is yet to be reported. In this study, new amphiphilic PCDA-taurine and PCDA-pBzS dopants were synthesized by changing the primary functional group to a sulfonic group. These polymerizable dopants are photopolymerized by UV irradiation in PANI solution. Thereby we expect to enhance the thermal stability and sustain the conductivity of PANI. The polymerizable dopants were characterized by FT-IR, NMR, and GC-MS. PANI with polymerizable dopants was analyzed by resonance Raman spectroscopy (RRS). The thermal stability and conductivity of PANI were characterized by thermogravimetric analysis (TGA). Comparing the TGA results of PANI doped with general dopants with PANI doped with polymerizable dopants, we found that PANI with polymerizable dopants showed enhanced thermal stability.
