Dispersion et Filage continu par coagulation de nanotubes de carbone

Abstract : This thesis deals with an original continuous spinning process of carbon nanotubes by coagulation. It focuses on characterization of surface chemical functions, morphology and dimensions of carbon nanotubes at each stage of the process. We present a quantitative study about the effects and kinetics of nanotubes scission induced by ultrasound. We present also the development of a continuous wet-spinning line. We propose methods for in-situ mechanical characterization of gel fibers, which enable a better control of physico-chemical parameters of the process. We hope that these results will participate to a better global comprehension of the effects of treatments used to obtain homogeneous carbon nanotubes suspension and to the development of continuous spinning process of high performance textile fibers.
