Effect of Carbon Fibers’ Surface Modification on the In Situ Growth of Carbon Nanotubes

Article Preview

Surface modification of carbon fibers(CF) by physicochemical methods directs an attractive approach for improvement of metal uptake from solutions. We investigated pretreatment of carbon fibers by HNO3 with different time on absorption of catalysts, which is related to the coverage of carbon nanotubes (CNTs) grown on Carbon fibers. The effects of surface modifications on the properties of carbon fibers were studied by X-Ray photoelectron spectroscopy. The modifications bring about variation in the chemical properties. The modification increased a large number of surface functional groups such as hydroxyl and carbonyl. The HNO3 modification increases the catalysts absorption. The coverage of CNTs on CF increases with pretreatment time, which was studied by SEM.
