Small but strong: A review of the mechanical properties of carbon nanotube–polymer composites

Carbon nanotube–polymer composites: Chemistry, processing, mechanical and electrical properties

Thermal conductivity of carbon nanotubes and their polymer nanocomposites: A review

Polymer/carbon nanotube (CNT) composites are expected to have good processability characteristics of the polymer and excellent functional properties of the CNTs. The critical challenge, however, is how to enhance dispersion and alignment of CNTs in the matrix. Here, we review recent progress and advances that have been made on: (a) dispersion of CNTs in a polymer matrix, including optimum blending, in situ polymerization and chemical functionalization; and (b) alignment of CNTs in the matrix enhanced by ex situ techniques, force and magnetic fields, electrospinning and liquid crystalline phase-induced methods. In addition, discussions on mechanical, thermal, electrical, electrochemical, optical and super-hydrophobic properties; and applications of polymer/CNT composites are included. Enhanced dispersion and alignment of CNTs in the polymer matrix will promote and extend the applications and developments of polymer/CNT nanocomposites.

Multicomponent blends based on polyamide 6 and styrenic polymers: morphology and melt rheology

The thermal behavior and morphology of multicomponent blends based on PA6, polyamide 6 (PA6)/styrene-acrylonitirle copolymer (SAN), PA6/acrylonitrile-butadiene-styrene terpolymer (ABS), and their compatibilized blends with styreneacrylonitrile-maleic anhydride copolymer (SANMA) were studied using DSC and SEM. The blends were prepared in a twin-screw extruder under similar processing conditions, keeping the PA6 content fixed at 50 wt %. It was found that, in all the blends, the second component had a nucleating effect and improved the overall degree and rate of crystallization of PA6, whereas addition of a compatibilizer slightly diminished these effects and resulted in significant changes in the blend morphology. The nucleating effect and consequent changes in the crystallization behavior was attributed to the presence of SAN, which is a common component in all the blends. The T g of PA6 in the blends with a cocontinuous morphology, due to the connectivity between the phases, is higher than in the blends with a disperse-type morphology. The compatibilized blends have a lower crystallization rate and nucleation ability with a cocontinuous morphology, whereas the uncompatibilized blends have a higher crystallization rate with a higher nucleation ability and a disperse and/or a coarse cocontinuous morphology.

A thermoplastic molding composition containing talc is disclosed. The composition wherein talc has a median particle size of less than 1000 nm further contains a polycarbonate and/or polyester-carbonate, and a graft polymer having as graft base a rubber having a glass transition temperature of below about 10° C. is suitable for preparing molded articles having improved mechanical properties, such as weld line strength, elongation at break and toughness at low temperatures.
