Silver nanowires with one-dimensional structures have attracted much research interest due to their potential applications in several areas. It is well-known that their properties strongly depend on the size and morphology of the silver nanostructures. Therefore, in our work, silver nanostructures were prepared using a polyol process and the effects of synthesis conditions on the formation and morphology of silver nanowires were investigated. | Effects of synthesis conditions on the formation and morphology of silver nanowires Vietnam Journal of Science and Technology 56 (2A) (2018 ) 111-117 EFFECTS OF SYNTHESIS CONDITIONS ON THE FORMATION AND MORPHOLOGY OF SILVER NANOWIRES Nguyen Truong Xuan Minh1, Quang The Anh1, Bui Thi Minh Thu1, Le Phuong Dung1, Tran Anh Duy1, Luu Hoang Tam2, Nguyen Tuan Anh1, Huynh Ky Phuong Ha1, Nguyen Truong Son1, * 1 Department of Chemical Engineering, Ho Chi Minh City University of Technology, VNU-HCM, 268 Ly Thuong Kiet St., Dist. 10, Ho Chi Minh City, Viet Nam 2 Department of Materials Technology, Ho Chi Minh City University of Technology, VNU-HCM, 268 Ly Thuong Kiet St., Dist. 10, Ho Chi Minh City, Viet Nam * Email: ntson@ Received: 08 April 2018; Accepted for publication: 13 May 2018 ABSTRACT Silver nanowires with one-dimensional structures have attracted much research interest due to their potential applications in several areas. It is well-known that their properties strongly depend on the size and morphology of the silver nanostructures. Therefore, in our work, silver nanostructures were prepared using a polyol process and the effects of synthesis conditions on the formation and morphology of silver nanowires were investigated. The structure and morphology of the synthesized silver nanostructures were characterized using transmission electron microscopy (TEM) and X-ray powder diffraction (XRD). The results showed that the morphology of the silver nanowires can be effectively controlled via adjusting parameters of the synthesis process. Keywords: silver, nanowires, one-dimensional, morphology control, polyol process. 1. INTRODUCTION One-dimensional (1D) nanostructures have received much attention due to their different properties compared to bulk structures [1]. Due to the high electrical and thermal conductivity of silver (Ag) compared to other metals, their 1D structures attracted considerable
