摘要

Polyaniline (PANI) stands out as a highly promising conductive polymer, finding extensive applications in optoelectronic and electronic fields due to its lightweight nature, flexibility, exceptional chemical and thermal stability, and impressive conductivity. Despite these advantages, PANI suffers from low transparency, primarily attributable to its opaque film and limited conductivity in neutral environments. This opacity not only reduces optical visibility but also adversely impacts the performance of PANI in transparent conductive sensors. To overcome these challenges, this study explores the influence of incorporating silver nanowires into PANI. PANI was synthesized with varying concentrations of silver nanowires (0%, 10%, 20%, and 30%) through in situ polymerization, using ammonium persulfate as the oxidizing agent. The composite materials were meticulously evaluated by measuring crystalline size, electrical conductivity, sensitivity, optical transparency, and sheet resistance. X-ray diffraction analysis confirmed the successful integration of silver nanowires into the PANI matrix, leading to notable enhancements in crystallinity, conductivity, stability, and sensitivity. The PANI containing 30% silver nanowires achieved an impressive crystalline size of 27 nm and demonstrated remarkable conductivity of 41 S/cm. Moreover, its sheet resistance decreased to an impressive 230 Ω/sq, while optical transparency soared to 63%. The sensitivity of the material also surged to 4.0, reflecting a staggering 400% improvement. The study discusses the trade-off between conductivity and transparency, revealing that the PANI/30% silver nanowire composite could provide balanced performance for transparent conductive sensor applications.
