Micro and Nano Silver-Graphene Composite Manufacturing via Horizontal Vapor Phase Growth (HVPG) Technique

Abstract

In this study, nanosilver-graphene composites were successfully manufactured via the horizontal vapor phase growth (HVPG) technique. A quartz tube loaded with the starting material, equal masses silver (Ag) powder and multi-layer graphene (Ge), was evacuated to ~10-6 Torr, sealed, and then baked at 1200°C for 6 hours, with its orientation such that a horizontal temperature gradient was generated across the tube. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) analysis revealed variations in the structure and composition of the nanomaterials deposited on different regions of the tube, and the diameter of the nanomaterials was found to decrease with decreasing temperature.
