Dispersion and functionalization of carbon nanotubes for polymer-based nanocomposites: a review
TLDR
In this paper, a review of the current understanding of carbon nanotubes and CNT/polymer nanocomposites with two particular topics: (i) the principles and techniques for CNT dispersion and functionalization and (ii) the effects of CNT-based functionalization on the properties of polymers.Abstract:
Carbon nanotubes (CNTs) hold the promise of delivering exceptional mechanical properties and multi-functional characteristics. Ever-increasing interest in applying CNTs in many different fields has led to continued efforts to develop dispersion and functionalization techniques. To employ CNTs as effective reinforcement in polymer nanocomposites, proper dispersion and appropriate interfacial adhesion between the CNTs and polymer matrix have to be guaranteed. This paper reviews the current understanding of CNTs and CNT/polymer nanocomposites with two particular topics: (i) the principles and techniques for CNT dispersion and functionalization and (ii) the effects of CNT dispersion and functionalization on the properties of CNT/polymer nanocomposites. The fabrication techniques and potential applications of CNT/polymer nanocomposites are also highlighted.read more

Graphene-functionalized polymer composites for self-sensing of ultrasonic waves: An initiative towards “sensor-free” structural health monitoring
TL;DR: In this article, a built-in sensing network is formed with graphene nanoparticles, optimized and diffused in fibre-reinforced polymers, in which the quantum tunneling effect can be locally triggered when GUWs traverse the composites.

CNT aggregation mechanisms probed by electrical and dielectric measurements
TL;DR: In this paper, electrical and dielectric measurements of carbon nanotubes in silicone oil were used to measure the percolation thresholds with a great accuracy, showing that a progressive separation between fillers and matrices is evidenced at a long time, this also results from the liquid nature of the matrix.

Improvement on the tensile performance of buckypaper using a novel dispersant and functionalized carbon nanotubes
TL;DR: In this paper, high tensile performance buckypaper (BPs) were prepared by commercially functionalized multiwalled carbon nanotubes (MWCNTs) with the aid of a novel dispersant, polyvinylpyrrolidone (PVP), and the tensile strength and modulus of PVP-BP were 227% and 295% higher than those of Triton X-100-BP, due to strong interactions between MWCNT and PVP.

TL;DR: X-ray diffraction and electron microscopy showed that fullerene single-wall nanotubes (SWNTs) are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms.
