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. | VNU Journal of Science: Mathematics – Physics, Vol 34, No. 1 (2018) 40-45 Facial Synthesis and Characterization of Polypyrrole/zinc oxide (ZnO) Nanorode and Flower-like Shape Composites Nguyen Xuan Sang1,*, Luu Thi Lan Anh2, Tran Thanh Thai3, Phan Trung Nghia4, Vo Thach Son2 1 Sai Gon University, 273 An Duong Vuong, Ward 3, District 5, Ho Chi Minh City School of Engineering Physics, Hanoi University of Science and Technology, Hanoi, Vietnam 3 Quy Nhon University, 170 An Duong Vuong, Quy Nhon, Binh Dinh, Vietnam 4 School of Chemical Engineering, Hanoi University of Science and Technology, Hanoi, Vietnam 2 Received 06 January 2018 Revised 21 January 2018; Accepted 05 February 2018 Abstract: Polypyrrole (PPy) nanocomposites reinforced with zinc oxide (ZnO) nanorod and nano flower are fabricated by chemical oxidative polymerization method using an ammonium persulphate (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. Keywords: PPy/ZnO nanocomposite, polymerization, FTIR, interconnection. 1. Introduction Recently, polymer nanocomposites have attracted great interest owing to their novel properties derived from the successful combination of the characteristics of parent constituents into a single material. The unparallel advantage such as cost-effective processability, lightweight and tunable mechanical, electrical and optical properties for the diverse applications such as microwave absorption, bio- and gas sensors, super capacitors [1- .
