“…Platelets can provide their restraint in two directions, when appropriately oriented, while fibers can only do so in one direction. Because of their shape differences, fibers can cause a greater reduction in the direction of their orientation than platelets can [166,170]. The CTE in the direction normal to the fibers or the platelet plane can actually increase when such fillers are added.…”

a b s t r a c tIn the large field of nanotechnology, polymer matrix based nanocomposites have become a prominent area of current research and development. Exfoliated clay-based nanocomposites have dominated the polymer literature but there are a large number of other significant areas of current and emerging interest. This review will detail the technology involved with exfoliated clay-based nanocomposites and also include other important areas including barrier properties, flammability resistance, biomedical applications, electrical/electronic/optoelectronic applications and fuel cell interests. The important question of the ''nano-effect'' of nanoparticle or fiber inclusion relative to their larger scale counterparts is addressed relative to crystallization and glass transition behavior. Of course, other polymer (and composite)-based properties derive benefits from nanoscale filler or fiber addition and these are addressed.

“…Several theoretical models are available for predicting the CTE of particulate composites [21][22][23][24][25], fiber-reinforced composites [26], and composites with aligned axisymmetric [27] and non-axisymmetric [28] ellipsoidal particles. Gunes et al [29] evaluated the effect of CTE on the shape memory performance of composites with different reinforcements and the experimental results were compared with theoretical models.…”

Ceramic particle-reinforced composites have better dimensional stability than the matrix polymer at high temperatures. In hollow-particle filled composites (syntactic foams), the coefficient of thermal expansion (CTE) can be controlled by two parameters simultaneously: wall thickness and volume fraction of particles, which are explored in this study. The CTE was experimentally measured to be up to 60.4 % lower than the matrix material with the addition of glass microballoons for the twelve compositions of syntactic foams characterized using a thermomechanical analyzer. The CTE values have a stronger dependence on particle volume fraction than the wall thickness within the range of parameters explored. The experimental trends are analyzed by using Turner's and Kerner's models modified for syntactic foams. The results from the modified Turner's model show close correlation with the experimental values with a maximum difference of ±15 %. Parametric studies show that syntactic foams of a wide range of densities can be tailored to obtain the same CTE value. The experimental and theoretical results are helpful in developing syntactic foams with desired properties for thermal applications.
