Surface functionalization and the
use of surfactant supported by sonication are general ways to solve
this problem [15–17]. Most of these methods have ineluctable
shortcomings, such as high cost, high risk and low efficiency. Furthermore,
fabrication of CNT/polymer composites with high CNT
content is also a difficult task. Therefore, developing a low-cost
and simple method to utilize CNTs in on a practicable scale is
always desirable.
