Effect of Temperature on the Esterification of Polyaniline Cellulose Acetate Composites (PANi). Supervised by LELA MUKMILAH and RENI MULYANI. The development of battery stones as a storage area for energy from organic materials is increasingly being used at this time, including using natural composites. In this research, a PANi-cellulose acetate composite was made as a battery stone material. The conductive polyaniline (PANi) material is composited with cellulose using the esterification method in which cellulose is made into cellulose acetate in the presence of temperature differences. Cellulose was extracted from corn cobs using delignification method with NaOH and NaOCl solutions. The esterification reaction of cellulose using acetic acid was carried out at temperatures of 0-5 oC and 27 oC. These results are then composited with PANi which is made from aniline and potassium dichromate as the initiator of oxidative polymerization. Cellulose acetate-PANi composites were characterized using an FT-IR and SEM-EDX spectrometer, while the determination of the conductivity value used an LCR-meter. FT-IR spectra of cellulose acetate-PANi composites showed a wave number at 1373cm-1 which is the bending vibration for C-H from OCOCH3 and 3429cm-1 is the wave number for the hydroxy group (- OH) vibration. SEM-EDX results show that PANi in the form of granules has adhered to the surface of cellulose acetate, so it can be said that PANi-cellulose acetate composites have been successfully synthesized. The conductivity value of cellulose acetate-PANi composites made at 0-5 oC and room temperature (27oC) were 5.69802x10-5 S/cm and 8.86852x10-4 S/cm respectively, which were semiconducting.} }
