Photoiniferter Synthesis of Cyclic Polymers from Vinyl Monomers Open
Cyclic polymers synthesized from vinyl monomers are somewhat rare in the chemical literature. Examples published to date often involve harsh reaction conditions and lack versatility toward the vinyl monomer type. Reported here is a photoin…

Polymer Spherulitic Growth Kinetics Mediated by Nanoparticle Assemblies Open
We systematically examine the role of the self-assembly state of polymer-grafted silica nanoparticles (GNPs) on the spherulitic growth kinetics of a poly(ethylene oxide) (PEO) matrix. The nanoparticles (NPs) are functionalized with either …

Surface and Particle Modification via the RAFT Process: Approach and Properties [Book Chapter] Open
The past decade has seen tremendous utility of reversible addition/fragmentation chain transfer (RAFT) polymerization to synthesize populations of polymers attached to surfaces (informally termed “brushes”). To date, many common RAFT agent…

Effects of Hairy Nanoparticles on Polymer Crystallization Kinetics Open
We previously showed that nanoparticles (NPs) could be ordered into structures by using the growth rate of polymer crystals as the control variable. In particular, for slow enough spherulitic growth fronts, the NPs grafted with amorphous p…

Nanoparticle Organization by Growing Polyethylene Crystal Fronts Open
We investigate the crystallization-induced ordering of C18 grafted 14 nm diameter spherical silica nanoparticles (NPs) in a short chain (Mw = 4 kDa, ĐM ≈ 2.3) polyethylene and a commercial high-density polyethylene (Mw = 152 kDa, ĐM ≈ 3.2)…

Postdoc perspective: Getting comfortable in a new lab Open
The most succinct way I can describe my experience as a postdoctoral researcher so far is to reference a quote I love by Gretchen Rubin: "The days are long, but the years are short." Since starting in my new lab last November, the first da…

Polyethylene Grafted Silica Nanoparticles Prepared via Surface-Initiated ROMP Open
Polyethylene and nanosilica represent the most ubiquitous commodity plastic and nanocomposite filler, respectively. Despite their potential utility, few examples exist in the literature of successfully combining these two materials to form…

Mechanical properties of polymer grafted nanoparticle composites Open
Polymer nanocomposites have improved mechanical, optical and thermal properties compared to traditional thermoplastics. To study the impact of grafted brush–matrix interactions on the mechanical properties of nanoparticle filled polymers, …

High-Capacity Poly(4-vinylpyridine) Grafted PolyHIPE Foams for Efficient Plutonium Separation and Purification Open
The use of anion-exchange resins to separate and purify plutonium from various sources represents a major bottleneck in the throughput that can be achieved when this step is part of a larger separation scheme. Slow sorption kinetics and br…
