Facial Synthesis and Characterization of Polypyrrole/zinc oxide (ZnO) Nanorode and Flower-like Shape Composites Authors: Nguyen, Xuan Sang Luu, Thi Lan Anh Tran, Thanh Thai Phan, Trung Nghia Vo, Thach Son Polypyrrole (PPy) nanocomposites reinforced with zinc oxide (ZnO) nanorod and nano flower were fabricated by chemical oxidative polymerization method using an ammonium per-sulphate (APS, (NH4)2S2O8) as an oxidizing agent. The polymer nanocomposite were characterized by X-ray diffractometer (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR). The results were compared with pure as-prepared PPy. The SEM images of the nanocomposites show homogeneous dispersion characteristics and different morphologies of ZnO structures such as rod and flower-like shapes. In the FTIR spectra, composite samples showed characteristic peaks of PPy shifted to higher positions confirmed the interfacial interactions between ZnO and PPy matrix... Link: http://repo
