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

Surfactant-aided dispersion of carbon nanomaterials in aqueous solution
TL;DR: In this paper, a review of different surfactants and their characterization methods for stable dispersion of carbon-based nanomaterials has been examined, and the usefulness of noncovalent functionalization using surfactant is due to its ability to efficiently unbundle carbon nanometres and sustain homogeneity of the nanofluids without compromising the integrity of their structure.
