TL;DR: In this article, the authors examine the status of nanoparticle dispersion in high-technology applications requiring unique electrical, thermal, and optical properties, and develop manufacturing techniques enabling control of the nanoparticle arrangement and distribution.
Abstract: Polymer nanocomposites (PNCs), i.e. nanoparticles (spheres, rods, and plates) dispersed in a polymer matrix, have garnered substantial academic and industrial interest since their inception, ca. 1990. With respect to the neat matrix, nanoparticle dispersion has been shown to enhance physical (e.g., barrier, erosion resistance, and reduced flammability), thermomechanical (e.g., heat distortion temperature, thermal expansion coefficient, and stiffness), and processing (e.g., surface finish and melt strength) characteristics. Beyond maximization of the nanoparticle dispersion, however, the morphology of these materials is many times uncontrolled, yielding isotropic nanofilled systems, not necessarily spatially “engineered, designed and tailored” materials. To impact high-technology applications requiring unique electrical, thermal, and optical properties, manufacturing techniques enabling control of the nanoparticle arrangement and distribution must be developed. This paper will examine the status of approac...

TL;DR: The impact of CNT density on thermal conduction considering boundary resistances, increased defect concentrations, and the possibility of suppressed phonon modes in the CNTs is discussed.
Abstract: Nanostructured composites containing aligned carbon nanotubes (CNTs) are very promising as interface materials for electronic systems and thermoelectric power generators. We report the first data for the thermal conductivity of densified, aligned multiwall CNT nanocomposite films for a range of CNT volume fractions. A 1 vol % CNT composite more than doubles the thermal conductivity of the base polymer. Denser arrays (17 vol % CNTs) enhance the thermal conductivity by as much as a factor of 18 and there is a nonlinear trend with CNT volume fraction. This article discusses the impact of CNT density on thermal conduction considering boundary resistances, increased defect concentrations, and the possibility of suppressed phonon modes in the CNTs.

TL;DR: In this article, the ablative performance of poly(caprolactam) (nylon 6) nanocomposites is examined, and it is shown that a relatively tough, inorganic char forms during the ablation of these nanocom composites resulting in at least an order-of-magnitude decrease in the mass loss (erosion) rate relative to the neat polymer.

TL;DR: In this paper, the authors highlight the frontier scientific research in the development of polymer nanocomposites for electrical energy storage applications, including the increase of the dielectric permittivity using high-permittivity ceramic fillers and conductive dopants, preparation of uniform composite films based on surface-functionalized fillers, and utilization of the interfacial coupling effect.
Abstract: This review highlights the frontier scientific research in the development of polymer nanocomposites for electrical energy storage applications. Considerable progress has been made over the past several years in the enhancement of the energy densities of the polymer nanocomposites via tuning the chemical structures of ceramic fillers and polymer matrix and engineering the polymer–ceramic interfaces. This article summarizes a range of current approaches to dielectric polymer nanocomposites, including the ferroelectric polymer matrix, increase of the dielectric permittivity using high-permittivity ceramic fillers and conductive dopants, preparation of uniform composite films based on surface-functionalized fillers, and utilization of the interfacial coupling effect. Primary attentions have been paid to the dielectric properties at different electric fields and their correlation with film morphology, chemical structure, and filler concentration. This article concludes with a discussion of scientific issues that remain to be addressed as well as recommendations for future research. © 2011 Wiley Periodicals, Inc.
