高密度超长碳纳米管的可控制备:进展与展望
Controlled synthesis of high-density ultralong carbon nanotubes:progress and prospects
摘要
Abstract
Carbon nanotubes(CNTs)have broad application prospects in many cutting-edge industrial applications,such as carbon-based integrated circuits,highly strong and tough fibers,mechanical energy storage,and flexible wearable devices due to their excellent mechanical,electrical,thermal and optical properties.The structures and morphologies(e.g.,length,degree of alignment,defect concentration,and degree of cleanliness)of CNTs have a significant impact on their fundamental physical properties.Among various kinds of CNTs,only ultralong CNTs with macroscale lengths,low defect concentrations,and high degrees of alignment can fully demonstrate their intrinsic performance,and meet the strict requirements of cutting-edge fields.The key to realizing the practical applications of ultralong CNTs is to realize their mass production.However,their yields can hardly satisfy the needs,indicating that the synthesis of ultralong CNTs with high densities and yields is still facing numerous challenges.This review discusses the growth mechanisms of ultralong CNTs,analyses the reasons for the low yield of ultralong CNTs,summarizes the methods for synthesizing high-density ultralong CNTs,and introduces the latest advances in the practical applications of ultralong CNTs.Besides,this review also summarizes the scientific and technological challenges and gives an in-depth discussion of the development directions in the synthesis of ultralong CNTs.关键词
