Nanocomposites Current Awareness
“Nanocomposites can be defined as multiphase solid materials where one of
the phases has a dimension of less than 100 nanometres (nm): structures having
nanometre scale dimensional repeat distances between the different phases that
make up the material. In the broadest sense this definition can include porous
media, colloids, gels and copolymers, but is more usually taken to mean the
solid combination of nano-dimensional phases differing in properties due to
dissimilarities in structure and chemistry. The mechanical, electrical, optical,
electrochemical, catalytic properties of the nanocomposite will differ markedly
from that of the component materials. Size limits for these effects have been
proposed, <5nm for catalytic activity, <20nm for making a hard magnetic material
soft, <50nm for refractive index changes, and <100nm for achieving
superparamagnetism, mechanical strengthening or restricting matrix dislocation
movement.”

Notes
“Nanocomposites are found in nature as for example in the structure of the
abalone shell and bone. The use of nanoparticle rich materials long predates the
understanding of the physical and chemical nature of these materials. Jose-Yacaman
et al investigated the origin of the depth of colour and the resistance
to acids and bio-corrosion of Maya blue paint, attributing it to a nanoparticle
mechanism. From the mid 1950s nanoscale organo-clays have been used to control
flow of polymer solutions (e.g. as paint viscosifiers) or the constitution of
gels (e.g. as a thickening substance in cosmetics, keeping the preparations in
homogeneous form). By the 1970s polymer/clay composites were the topic of
textbooks, although the term "nanocomposites" was not in common use.”

***********************************************
“In mechanical terms, nanocomposites differ from conventional composite
materials due to the exceptionally high surface to volume ratio of the
reinforcing phase. The reinforcing material can be made up of particles e.g.
exfoliated clay particles, short fibres e.g carbon nanotubes, or long fibres
e.g. electrospun fibres. The area of the interface between the matrix and
reinforcement phases is typically an order of magnitude greater than that in
conventional composite materials. The matrix material is significantly affected
by proximity to the reinforcement. Ajayan et al note that with polymer
nanocomposites, properties related to local chemistry, degree of thermoset cure,
polymer chain mobility, polymer chain conformation, polymer chain conformation,
degree of polymer chain ordering or crystallinity can all vary significantly and
continuously from being in contact with the reinforcement into the bulk of the
matrix. This large amount of reinforcement surface area means that the effect of
a relatively small amount of nanoscale reinforcement can have an observable
effect on the macroscale properties of the composite. For example, adding carbon
nanotubes improves the electrical and thermal conductivity. Other kinds of
nanoparticulates may result in enhanced optical properties, dielectric
properties or mechanical properties such as stiffness and strength. In general,
the nano reinforcement is dispersed into the matrix during processing. The
percentage by weight (called mass fraction) of the nanoparticulates
introduced can remain very low (on the order of 0.5% to 5%) due to the low
filler percolation threshold, especially for the most commonly used
non-spherical, high aspect ratio fillers (e.g. nanometer-thin platelets, such as
clays, or nanometer -diameter cylinders, such as carbon nanotubes).”
