Nanoparticle assembly modulated by polymer chain conformation in composite materials

Abstract

<p>Nanoparticle aggregation in a nanocomposite can be physically modulated by the polymer conformational change into open fractal structures.</p>

Biobased foams for thermal insulation: material selection, processing, modelling, and performance

“…The growing push towards a more sustainable, circular economy has increased attention on biobased materials that are useful in many applications including coatings, adhesives, medical equipment and single use packaging. [1][2][3][4] Besides being more sustainable, multiple studies show that replacing petroleum-based materials with biobased alternatives signicantly reduces environmentally harmful emissions. [5][6][7][8][9][10] Additionally, biobased materials are oen biodegradable, thus reducing landll waste accumulation.…”

Biobased superhydrophobic coating enabled by nanoparticle assembly

“…In addition, polymer morphology and entropy (depletion force) may play important roles in modulating interparticle interactions. [27][28][29][30][31][32] To probe interparticle interactions and assembly mechanisms within biobased polymers, we adopt integrated advanced tools, including liquid-phase atomic force microscopy (AFM) and computational simulation. In in situ AFM, a uid environment can be used to replicate the wet condition, where adhesion is measured with a microscale colloidal probe mounted on the scanning tip.…”

Ionic Polymer Nanocomposites Subjected to Uniaxial Extension: A Nonequilibrium Molecular Dynamics Study

“…Our model systems are composed of spherical NPs and multibead-spring linear polymer chains (so-called Kremer-Grest polymers [44][45][46]), where each bead represents a number of monomers [47,48]. Adjacent beads within chains are connected by anharmonic springs, while the impenetrable NPs are modeled as rigid, mobile objects whose surfaces are covered by NP surface beads.…”
