“…Firstly, the newly introduced preparation protocol results in a polyHIPE with dramatically increased pore interconnectivity, which inversely affects the structural integrity of the foam. Secondly, carbon black acts as strong radical scavenger, 31 which leads to the in situ grafting by the termination of growing polymer radicals, which enhances the stability of the carbon black suspension but it might also lead to the formation of a weak interface between the grafted particles and the surrounding crosslinked polymer matrix. If that is the case the carbon black particles will act as stress points within the pore walls causing the mechanical properties to decrease.…”

A series of carbon black filled polyHIPEs was synthesised following a new preparation protocol. 1 wt% carbon black was dispersed in the monomer mixture. In order to enhance the stability of the suspension, in situ polymer grafting of carbon black was performed by initiating the polymerisation prior to emulsifying the formulation. All of the carbon black filled polymer foams synthesised via the new preparation protocol have the characteristics usually observed for polyHIPEs. Carbon black particles are incorporated into the pore walls without affecting the pore structure of the polyHIPEs. The new preparation protocol positively influenced the properties of the resulting polyHIPEs namely the pore interconnectivity is increased and a water permeability of up to 2.3 D is achieved.

“…The grafting to method is quite simple and modular since the step involved is attachment of an end functionalized polymer to the surface. 241,242 However, there is a problem of strong steric repulsion between the attached chain and the diffusing chain. This factor hinders the grafting density.…”

Polyelectrolyte brushes: theory, modelling, synthesis and applications

et al. 2015

Polyelectrolyte (PE) brushes are a special class of polymer brushes (PBs) containing charges. Polymer chains attain "brush"-like configuration when they are grafted or get localized at an interface (solid-fluid or liquid-fluid) with sufficiently close proximity between two-adjacent grafted polymer chains - such a proximity triggers a particular nature of interaction between the adjacent polymer molecules forcing them to stretch orthogonally to the grafting interface, instead of random-coil arrangement. In this review, we discuss the theory, synthesis, and applications of PE brushes. The theoretical discussion starts with the standard scaling concepts for polymer and PE brushes; following that, we shed light on the state of the art in continuum modelling approaches for polymer and PE brushes directed towards analysis beyond the scaling calculations. A special emphasis is laid in pinpointing the cases for which the PE electrostatic effects can be de-coupled from the PE entropic and excluded volume effects; such de-coupling is necessary to appropriately probe the complicated electrostatic effects arising from pH-dependent charging of the PE brushes and the use of these effects for driving liquid and ion transport at the interfaces covered with PE brushes. We also discuss the atomistic simulation approaches for polymer and PE brushes. Next we provide a detailed review of the existing approaches for the synthesis of polymer and PE brushes on interfaces, nanoparticles, and nanochannels, including mixed brushes and patterned brushes. Finally, we discuss some of the possible applications and future developments of polymer and PE brushes grafted on a variety of interfaces.

“…The material shifted from insulating to conductive form. Yoshikawa et al 89 studied grafting of PS with controlled molecular weight and narrow molecular weight distribution on CB surface. Polymer radicals were formed by thermal dissociation of 2,2,6,6-tetramethyl-1-piperidinyloxy-terminated PS on CB surface.…”

This article appraises the contemporary reinforcement of carbon black in different polymer matrices. Essential features of polymer/carbon black composites are influenced by particle size, surface area, and surface chemistry of filler. Special emphasis is placed on recent research trends attained using polymer/carbon black composites. These materials have potential in fuel cells, sensors, detectors, supercapacitors, electromagnetic interference shielding, shape memory, dye-sensitized solar cells, and coatings. Various aspects, such as interfacial interaction, processing conditions, particle dispersion, and other physical properties, are highlighted for further exploration to discover hidden possibilities for these indispensable polymer composites.
