Abstract:
|
Carbon nanofibre-reinforced polypropylene nanocomposites containing from 5 to 20
wt.% of carbon nanofibres and a chemical blowing agent were melt-compounded and later foamed
using compression-moulding. Alongside their foaming behaviour analysis and cellular
characterization, foams showing an increasingly finer isometric cellular structure with increasing
the amount of nanofibres, their thermal conductivity was determined using the Transient Plane
Source Method (TPS). Contrarily to the electrical conductivity, which has previously been shown to
rise with increasing the amount of carbon nanofibres [1], the addition of the nanofibres did not
significantly alter the thermal conductivity of the PP foams, their value being mainly affected by the
relative density, only slight differences being assessed for the higher expansion ratio PP-CNF foams |
