- Soft lithography microfabrication of functionalized thermoplastics by solvent casting
Eric L. Kendall, Jung Yeon Han, Michael S. Wiederoder, Alex Sposito, Andrew Wilson, Omid D. Rahmanian and Don L. DeVoe
Article first published online: 29 JUN 2015 | DOI: 10.1002/polb.23766
Functional thermoplastic microstructures are molded by solvent casting on a solvent permeable elastomer mold. The soft lithographic technique enables the fabrication of microscale thermoplastic structures with embedded functionality without the use of specialized equipment. Rapid gelation of supersaturated thermoplastic solutions allows the deposition of multiple patterned layers, enabling the fabrication of microfluidic devices with embedded sensors and conductive elements.
- Photo-hardenable and patternable PDMS/SU-8 hybrid functional material: A smart substrate for flexible systems

By simply mixing two commercial products widely used in micro- and nanotechnology, namely polydimethylsiloxane (PDMS) and a photoresist (SU-8), a photo-hardenable and photopatternable hybrid functional material compatible with ultraviolet photolithography is created. The stiffness can be locally increased by ∼35% whilst ∼5 μm deep features are demonstrated for micrometer size mask patterns. Such smart substrates, as demonstrated here, could have uses in flexible systems and electronics, micromolding and soft lithography, and microfluidics.
- Epoxy resin curing reaction studied by proton multiple-quantum NMR

1H Multiple Quantum (MQ)-NMR spectroscopy is a successful approach for characterizing the network structure and segmental dynamics, at the molecular level, of high dipolar-coupled thermosetting polymer networks. The most important structural factors that define the cured resins, for example, fraction of non-coupled segments/molecules, the cross-link density and the spatial distribution of cross-links, were studied. Additionally, the curing kinetics can be easily monitored in order to obtain parameters such as the induction and vitrification times, polymerization rate and activation energy.
- Modeling effect of ferroelectric nanofiller size on bipolar charge transport in nanocomposite film
Meng H. Lean and Wei-Ping L. Chu
Article first published online: 29 JUN 2015 | DOI: 10.1002/polb.23775
Ceramic nanofillers are incorporated within amorphous polymer binders to result in nanocomposite films for use in energy storage for rapid power cycling applications. Using a rapid 3D particle simulation algorithm, this work investigates bipolar charge injection, transport, attachment, and recombination (or electroluminescence) through nanocomposite films comprising ferroelectric BaTiO3 nanofillers in an amorphous PVDF polymer matrix for various polarizations and for a range of nanofiller sizes.
- Enhanced electrostriction based on plasticized relaxor ferroelectric P(VDF-TrFE-CFE/CTFE) blends
Jean-Fabien Capsal, Jeremy Galineau, Minh-Quyen Le, Fabrice Domingues Dos Santos and Pierre-Jean Cottinet
Article first published online: 29 JUN 2015 | DOI: 10.1002/polb.23776
Due to their large strain induced under electric field, low weight, good mechanical properties, and easy processability, electrostrictive organic materials show promising potential in various applications where electromechanical conversion is required, such as low frequency energy harvesting or actuation in micropumps and artificial muscles. In this work, plasticized effects as well as the influence of chlorofluoroethylene and chlorotrifluoroethylene defects on the electromechanical behavior the copolymer matrix poly(vinylidene fluoride-trifluoroethylene) are investigated.
