Solid particles in an elastomer matrix: impact of colloid dispersion and polymer mobility modification on the mechanical properties
TL;DR: In this paper, a suitable silica-filled model elastomer is presented, where the authors characterize the silica dispersion by SANS in combination with reverse Monte-Carlo modeling, and the mobility modification of the polymer by low-field proton NMR spectroscopy.
Contrast variation SANS measurement of shell monomer density profiles of smart core-shell microgels

TL;DR: The radial density profile of deuterated poly(N,n-propyl acrylamide) shell monomers within core-shell microgels has been studied by small-angle neutron scattering in order to shed light on the origin of their linear thermally-induced swelling.
Swelling behaviour of core-shell microgels in H2O, analysed by temperature-dependent FTIR spectroscopy.
Lars Wiehemeier,Marian Cors,Marian Cors,Oliver Wrede,Julian Oberdisse,Thomas Hellweg,Tilman Kottke +6 more
TL;DR: Temperature-dependent FTIR spectroscopy is a convenient approach to elucidate the internal architecture of complex microgel particles in H2O and shows a broadening and shift of the respective phase transition temperatures of the core and shell indicating an interaction of thecore and shell polymers on a molecular level that extends far into the core.
Structure of interacting aggregates of silica nanoparticles in a polymer matrix: small-angle scattering and reverse Monte Carlo simulations
TL;DR: In this article, the three-dimensional structure of large aggregates of nanometric silica particles embedded in a soft polymeric matrix is determined by small angle neutron scattering, and the total signal is analyzed by means of a decomposition in a classical colloidal structure factor describing aggregate interaction and an aggregate form factor determined by a reverse Monte Carlo technique.
How Tuning Interfaces Impacts the Dynamics and Structure of Polymer Nanocomposites Simultaneously.

TL;DR: In this article , the effect of surface modification by alkyl methoxysilanes at different grafting densities has been studied in PNCs made of poly(2-vinylpyridine) and spherical 20 nm silica NPs.
