The fabrication of well-defined, multifunctional polymer brushes under ambient conditions is described. This facile method uses light-mediated, metal-free atom-transfer radical polymerization (ATRP) to grow polymer brushes with only microliter volumes req

We designed, synthesized and characterized several novel hybrid inorganic/organic nanocomposite electrolytes that consist of poly(ethylene oxide) (PEO) based polymer grafted from silica nanoparticles. Poly(ethylene glycol)methyl ether methacrylate (PEGMA) was tailored on the silica surface through atom transfer radical polymerization (ATRP). A series of silica-polymers were synthesized with different lengths of PEO side chains. Electrolytes were prepared from the functionalized particles and low-molecular weight polyethylene glycol dimethyl ether (PEGDME) with the addition of LiI. Upon the introduction of particles, electrolytes became viscous and gel-like. With the increase of PEO side chains, the viscosity of the electrolytes increased dramatically, among which, silica-poly(PEGMA-1100) became solid-state. The room temperature conductivities of the hybrid silica-polymer electrolytes are in the range of 6 × 10-5to 1.2 × 10-4S cm-1. Silica-poly(PEGMA-475) and silica-poly(PEGMA-1100), with higher viscosity, exhibited better ionic conductivity. Surface-initiated copolymerization was also conducted to optimize the electrochemical performance of polymer coated silica nanoparticles. This journal is

In this work, a postpolymerization surface modification approach is reported that provides pendent thiol functionality along the polymer brush backbone using the photolabile protection chemistry of both o-nitrobenzyl and p-methoxyphenacyl thioethers. Poly

A facile approach to unique 3D, patterned polymer brushes is based on visible-light-mediated controlled radical polymerization. The temporal and spatial control of the polymerization allows the patterning of polymer brushes from a uniform initiating layer using a simple photomask (see picture). Furthermore, gradient polymer brushes, patterned block copolymers, and complex 3D structures can be obtained by modulating light intensity. Copyright

(Figure Presented) We demonstrate a facile method for fabricating novel 3D microfluidic channels by using two-photon-activated chemistry to locally switch the interior surface of a porous host from a hydrophobic state to a hydrophilic state. The 3D structures can be infilled selectively with water and/or hydrophobic oil with a minimum feature size of only a few micrometers. We envision that this approach may enable the fabrication of complex microfluidic structures that cannot be easily formed via current technologies.
