Dispersion and alignment of carbon nanotubes in polymer matrix: A review
TLDR
In this article, the authors 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 CNNs in the matrix enhanced by ex situ techniques, force and magnetic fields, electrospinning and liquid crystalline phase-induced methods.Abstract:
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.read more

Preparation and characterization of nematic polyazomethine/single-walled carbon nanotube composites prepared by in situ polymerization
TL;DR: In this paper, the synthesis and characterization of a series of nematic SWNT-polyazomethine composites are described. The composites were prepared by in situ polymerization in the presence of 1 wt % of chemically modified SWNTs in such a way that they were either dispersed or covalently bonded to the polymeric matrix.

Mapping viscoelastic and plastic properties of polymers and polymer-nanotube composites using instrumented indentation
Andrew J. Gayle,Robert F. Cook +1 more
TL;DR: Open-form solutions for indentation displacement under constant load and constant loading-rate are developed and used to determine and validate material properties and revealed considerable spatial heterogeneity in the slow viscoelastic and plastic responses in the composites, particularly in the material with a greater fraction of nanotubes.
