4. Conclusions
Using a chemical blowing agent, PBS/CNFs nanocomposite foams
with a closed-cell structure and high blowing ratio was successfully
obtained. It was found that to produce the high performance-
nanocomposite foams, the optimal CNFs content was 2 wt%, and the
SOAM method was an effective way to disperse the CNFs in the PBS
matrix based on the enhancement of thermal and mechanical
properties for the nanocomposites. In foaming process, when the
decomposition of CBA occurred in a nanocomposite melt, well-
dispersed CNFs acted as the efficient nucleation sites in the PBS
matrix-CNFs interface. Nanocomposite foams exhibited the oval-shape
and the homogeneous closed-cell structures without any ruptures. A
high blowing ratio of about 12 was obtained at 170 ºC for 30 min, as
well as a uniform cell size distribution of nanocomposite foams
observed.
