Processing and Applications of CNT Sheets in Advanced Composite Materials

Abstract The development of synthesis techniques such as chemical vapor deposition (CVD) and floating catalyst CVD (FCCVD) has transformed CNTs from being property enhancing fillers in composites to structural materials of the future. These advanced synthesis techniques allow for ease in manufacturing of CNT sheets and their composites with other materials such as polymers and metals. Multipurpose CNT sheet composites find application in a variety of fields such as aerospace and energy storage. This chapter provides an insight into the development of the various techniques for manufacturing and processing of CNT sheets based on a review in the literature combined with our own experience. The “role reversal” in the development of high-strength CNT/polymer sheet composites, where the CNT is the majority phase, is discussed. CNT sheets are also excellent candidates for application as flexible, freestanding electrodes.
