This study attempts to produce polyaniline (PAni)/Alkyd films with short curing time, good adhesion on fluoride-doped tin oxide (FTO) glass and having high conductivity that can be apply in solar cell panel. Both palm stearin-based alkyd resins and PAni were synthesized via chemical reactions. Chemical structures of the palm oil-based alkyd and PAni were investigated by proton nuclear magnetic resonance (1H NMR), Fourier Transform Infrared (FTIR), and Ultraviolet-visible (UV-vis) spectrometers. Palm oil-based alkyds having three different acid number (AN) (5.66, 14.74, and 17.60 mg KOH/g) were blended with PAni at ratio of 1:0.5, 1:0.75, 1:1 for the preparation of PAni/Alkyd films via UV curing method. UV-vis spectrometer confirmed the chemical structure of PAni/Alkyd films. The adhesion of Pani/Alkyd films were tested following ASTM D3359 and conductivity study of PAni/Alkyd films was carried out using four point probe method. Best result was observed for PAni/ Alkyd at a ratio 1:0.5 with the palm oil-based alkyd having AN value of 5.56 mg KOH/g. The shortest curing time was 10 minutes, with strong adhesion of PAni/Alkyd films on FTO glass and conductivity of 2.56102 S/cm. By comparison the conductivity of the pure PAni was 1.31×103 S/cm.

This study attempts to improve the adhesion and conductivity of polyaniline (PAni) by incorporating an alkyd and titanium dioxide (TiO2), respectively. PAni with different TiO2 content (10, 20, and 40%) are synthesized through chemical oxidation method by using aniline (Ani) monomer, dioctyl sodium sulfosuccinate (AOT) dopant, and ammonium persulphate (APS) oxidant at 0 °C for 24 h. In order to improve the adhesion of PAni‐TiO2 on fluoride doped‐tin oxide (FTO) glass prior to its application as counter electrode (CE) in Dye‐Sensitized Solar Cell (DSSC), a palm oil‐based alkyd is added into PAni‐TiO2 composite. Chemical structures of PAni‐TiO2/Alkyd are confirmed by Fourier transform infrared spectrophotometer (FTIR) and ultraviolet‐visible (UV‐Vis) spectrophotometry analyses. Conductivity measurement is determined by using four point probe method and adhesion test is performed following ASTM D3599. Results showed that conductivity of PAni had significantly improved from 3.53 × 10−3 (without TiO2) to 8.16 × 10−3–6.59 × 10−2 S cm−1 (with TiO2). However, the conductivity of all PAni‐TiO2/Alkyd samples on FTO glass showed high conductivity (6.11–6.32 × 102 S cm−1) and better adhesion behavior on FTO glass except for the sample with 40% of TiO2. The plausible mechanisms between PAni‐TiO2/Alkyd and FTO glass are proposed in this study based on the FTIR and UV‐Vis analyses.
