Self-assembled morphologies of polyelectrolyte-grafted nanoparticles directed by oppositely charged polymer matrices

Abstract

Self-assembled structure of polymer grafted nanoparticles is an interesting and growing subject in the field of hybrid electronics and high energy density materials.

From Ionic Nanoparticle Organic Hybrids to Ionic Nanocomposites: Structure, Dynamics, and Properties: A Review

“…Solvent-free ionic nanosilica particles were uniformly dispersed in an epoxy matrix. The addition of even the low loading of such ionic nanofillers greatly improved the tribological performance of the epoxy [ 56 , 57 ]. Furthermore, TEM images disclosed a good dispersion of surface-modified sulfonated nanosilicas, of up to 20% wt loading, in entangled imidazolium functionalized polyurethane (im-PU) matrices [ 58 ] and up to 5% wt loading, in an entangled rigid imidazolium terminated (im-PLA) and soft poly[ -caprolactone-co-D,Llactide] (im-P[CL-co-LA]) [ 59 ].…”

“…Ionic graphene/nanosilica organic hybrids were synthesized by attaching nanosilica (SiO of diameter 100 nm), which was functionalized by SIT, on graphene oxide (GO), and ionically tethered to Jeffamine M-2070 [ 106 ]. Such an ionic organic hybrid showed very good dispersion stability, as characterized by TEM [ 57 ]. Another graphene ionic nanoparticle organic hybrid was synthesized, that could also be dispersed in a variety of solvents, by taking a different approach using a non-covalent modifier, through the chemical reduction of graphene oxide (GO) using a fluorescent whitening agent, VBL, and interacting with electrostatic interaction with bulky Jeffamine M-2070, as can be seen in Figure 9 [ 107 ].…”
