英语翻译
the average length of the dispersed clay particles,and
hence the aspect ratio.Fig.81 represents the
dependence of the tensile modulus E measured at
120 8C for exfoliated N6 nanocomposites with various
clay content,obtained by the in situ intercalative
polymerization of 1-caprolactam in the presence of
protonated aminododecanoic acid-modified MMT
and saponite.Moreover,the difference in the extent
of exfoliation,as observed for N6-based nanocomposites
synthesized by the in situ intercalative polymerization
of 1-caprolactam using Naþ-MMT and
various acids,strongly influenced the final modulus
of the nanocomposites.
Table 14 summarizes the tensile modulus of
1potNCH together with neat N6 and NCH prepared
via in situ intercalative ring-opening polymerization
of 1-caprolactam [135].The excellent modulus in the
case of 1potNCH is attributed to the uniformly
dispersed silicate layers.Furthermore,1potNCH has
improved mechanical properties when compared with
NCH.The polymer matrix in the nanocomposites
prepared by a one pot synthesis is the homopolymer of
N6,whereas in the case of NCH prepared via
intercalative ring-opening polymerization,the matrix
is a copolymer of N6 and a small amount of N12.The
presence of N12 may give rise to the lower modulus.
One can observe variations of the modulus of the
nanocomposites based on the various kinds of
acids used to catalyze the polymerization [135].
The WAXD peak intensity (Im; inversely related to
the exfoliation of clay particles) also depends on the
nature of the acid used to catalyze the polymerization
process.For an increase in the Im values,a parallel
decrease in the modulus is observed,indicating that
exfoliated layers are the main factor responsible for
the stiffness improvement.Intercalated particles,
having a less important aspect ratio,play a minor
role.These observations are further confirmed in
Fig.82,which presents the evolution of the tensile
modulus at room temperature of N6 nanocomposites
obtained by melt extrusion as a function of the filler
content [142]
