Abstract

Polypyrrole-poly ethylene glycol (Ppy-PEG) composites were synthesized by electrochemical method using r-toluene sulfonate as a dopant in aqueous medium. Polyethylene glycol was used as the insulating material in order to impart enhanced mechanical properties to the conducting polymer composite films. The composite films were synthesized with various percentages of PEG, and were characterized by FT-IR spectroscopy, conductivity measurement, optical microscopy (OP), X-ray diffraction (XRD) and dynamic mechanical analysis (DMA). The FT-IR result reveals the successful incorporation of PEG into the polypyrrole structure forming Ppy-PEG composite films. The conductivity of the composite films prepared from using 0.20% PEG was found to exhibit the highest conductivity (61.28 Scm-1) among all the prepared composite films measured at room temperature. The optical microscopy of Ppy-PEG shows the globular surface morphology. The XRD analysis of Ppy-PEG composite films shows that the composite films are amorphous. The enhanced mechanical properties of the Ppy-PEG composite films are the direct consequence of incorporating PEG in the polypyrrole structure.


Polipirol-polietilena glikol (Ppy-PEG) komposit telah disintesiskan secara elektrokimia memggunakan r-toluena sulfonat sebagai dopan dalam perantara akueus. Polietilena glikol digunakan sebagai bahan penebat untuk menguatkan sifat mekanik terhadap filem polimer pengalir. Filem polimer pengalir telah disediakan dengan pelbagai peratus PEG dan dicirikan dengan menggunakan spektroskopi FT-IR, pengukuran konduktiviti, mikroskopi optik (OP), pengimbasan analisis sinar-X dan analisis mekanikal dinamik (DMA). Kajian FT-IR ke atas filem komposit PPy -PEG nyata menunjukkan kemasukan PEG ke dalam struktur polipirol berkaitan dengan pembentukan filem komposit Ppy-PEG. Filem komposit Ppy-PEG dengan menggunakan 0.20% PEG telah memberi nilai konduktiviti tertinggi iaitu 61.28 Scm-berbanding dengan yang lain pada suhu bilik. Mikroskopi optik Ppy-PEG menunjukkan sifat morfologi permukaannya yang berbentuk sfera. Keputusan XRD menunjukkan bahawa filem komposit Ppy-PEG adalah bersifat amorfus. Peningkatan sifat mekanik untuk Ppy-PEG filem komposit adalah akibat daripada kemasukan PEG dalam struktur polipirol.
