Abstract

Binary polymer nanoparticle glasses offer opportunities to realize the facile assembly of disparate components, with control over nanoscale and mesoscale domains, for the development of functional materials. Our report demonstrates that tunable electrical percolation can be achieved through semiconducting/insulating polymer nanoparticle glasses by varying the relative percentages of equal-sized nanoparticle constituents of the binary assembly. Using time-of-flight charge carrier mobility measurements and conducting atomic force microscopy, we show that these systems exhibit power law scaling percolation behavior with percolation thresholds of ~24–30%. We develop a simple resistor network model, which can reproduce the experimental data, and can be used to predict percolation trends in binary polymer nanoparticle glasses. Finally, we analyze the cluster statistics of simulated binary nanoparticle glasses, and characterize them according to their predominant local motifs as (p_i, p_1-i)-connected networks that can be used as a supramolecular toolbox for rational material design based on polymer nanoparticles.

Polymer Nanoparticle Assemblies: A Versatile Route to Functional Mesostructures

Journal Article Renna, Lawrence A. ; Boyle, Connor J. ; Gehan, Timothy S. ; ... - Macromolecules

Fabricating macromolecular mesoscale assemblies containing disparate components with targeted molecular order for each of the components on the nanoscale and targeted assembly of the components in the mesoscale is a challenge. In this Perspective, we explore the self-assembly of polymer nanoparticles as a viable route to obtain tunable mesostructured materials. Here, we describe the state-of-the-art methods available for and the challenges to obtain spherical and nonspherical polymer nanoparticles. We discuss the predicted ordered assemblies and disordered assemblies of nanoparticles and the challenges to obtain these assemblies in polymer nanoparticles. We also comment on the rich and future opportunities in themore »« less

Programmable Anisotropy and Percolation in Supramolecular Patchy Particle Gels

Journal Article Song, Jake ; Rizvi, Mehedi H. ; Lynch, Brian B. ; ... - ACS Nano

Patchy particle interactions are predicted to facilitate the controlled self-assembly and arrest of particles into phase-stable and morphologically tunable "equilibrium" gels, which avoids the arrested phase separation and subsequent aging that is typically observed in traditional particle gels with isotropic interactions. Despite these promising traits of patchy particle interactions, such tunable equilibrium gels have yet to be realized in the laboratory due to experimental limitations associated with synthesizing patchy particles in high yield. Here, we introduce a supramolecular metal-coordination platform consisting of metallic nanoparticles linked by telechelic polymer chains, which validates the predictions associated with patchy particle interactions and facilitatesmore »« less

The influence of semiconductive binary Sb{sub 2}S{sub 3}–Yb{sub 3}S{sub 4} system on electrical conductivity property of epoxy composites

Journal Article Soydal, Ulku ; Ahmetli, Gulnare ; Kocaman, Suheyla - AIP Conference Proceedings

The purpose of this study is to develop the semiconductive composites. Semiconducting glass (SG) binary system Sb{sub 2}S{sub 3}–Yb{sub 3}S{sub 4} in mole ratio 1:1 was synthesized and was doped with I{sub 2}. Next, electrically conductive DGEBA-type epoxy resin (ER)/SG-filled composites and epoxy toluene oligomer (ETO) modified epoxy resin-SG filled composites were developed with 3–10 wt. % of fillers and characterized. As a result, the effects of the modifier and amount of semiconductive filler on the electrical properties of commercial epoxy resin were examined. Percolation concentration was 7 wt. % for all composites. For the SG-reinforced composites, the dispersion ofmore »« less

Quasicrystalline order in self-assembled binary nanoparticle superlattices.

Journal Article Shevchenko, E V ; Talapin, D V ; Bodnarchuk, M I ; ... - Nature

The discovery of quasicrystals in 1984 changed our view of ordered solids as periodic structures and introduced new long-range-ordered phases lacking any translational symmetry. Quasicrystals permit symmetry operations forbidden in classical crystallography, for example five-, eight-, ten- and 12-fold rotations, yet have sharp diffraction peaks. Intermetallic compounds have been observed to form both metastable and energetically stabilized quasicrystals; quasicrystalline order has also been reported for the tantalum telluride phase with an approximate Ta{sub 1.6}Te composition. Later, quasicrystals were discovered in soft matter, namely supramolecular structures of organic dendrimers and tri-block copolymers, and micrometre-sized colloidal spheres have been arranged into quasicrystallinemore »« less

Nickel(ii) complexes based on dithiolate–polyamine binary ligand systems: crystal structures, hirshfeld surface analysis, theoretical study, and catalytic activity study on photocatalytic hydrogen generation

Journal Article Adhikari, Suman ; Bhattacharjee, Tirtha ; Bhattacharjee, Sharmila ; ... - Dalton Transactions

To ascertain the influence of binary ligand systems [1,1-dicyanoethylene-2,2-dithiolate (i-mnt^-2) and polyamine {tetraen = tris(2-aminoethyl)amine, tren = diethylene triamine and opda = o-phenylenediamine}] on the coordination modes of the Ni(II) metal center and resulting supramolecular architectures, a series of nickel(II) thiolate complexes [Ni(tetraen)(i-mnt)](DMSO) (1), [Ni₂(tren)₂(i-mnt)₂] (2), and [Ni₂(i-mnt)₂(opda)₂]_n (3) have been synthesized in high yield in one step in water and structurally characterized by single crystal X-ray crystallography and spectroscopic techniques. X-ray diffraction studies disclose the diverse i-mnt^-2 coordination to the Ni⁺² center in the presence of active polyamine ligands, forming a slightly distorted octahedral geometry (NiN₄S₂) in 1, squaremore »« less
