Due to their promising electrical, chemical and mechanical properties, carbon nanotubes (CNT) have been studied for their potential to achieve practical applications in a wide range of areas. During the past decade there have been considerable efforts towards applications using vertically aligned CNT. Studies of the kinetics of the growth have not only made it possible to optimize the length and quality of the CNTs but have also given better understanding of the basic mechanisms involved in CNT growth. We have studied the initial kinetics of CNT growth using in-situ measurements of laser transmittance and followed growth for longer times by stopping at certain growth times and performed SEM, TEM and micro Raman characterization. Kinetics was obtained for different growth conditions by varying growth temperature, partial pressure of feedstock and composition of catalyst. |
