Abstract:The dispersion of carbon nanotubes in epoxy resin fabricated in different technological conditions was
macroscopical characterized by stewing oberservation, viscosity and fineness respectively. The results reveal that as
the dispersion of carbon nanotubes is good, the viscosity of epoxy is big, the fineness is low, and the conserving time
is long. There are three means could all characterize the dispersion uniformity of carbon nanotubes, viscosity and fine鄄
ness could characterize the dispersion of carbon nanotubes quickly, but the specific evaluation criterion should be
found before. In this paper, the dispersions of carbon nanotubes were characterized quickly by establishing the corre鄄
sponding relation of scraper fineness and the dispersion. This method is quick, direct, accurate and easily operated,
compared to conventional micro-characterization technique.
