  1. On the stability of nanoparticles coated with polyelectrolytes in high salinity solutions

    Rikkert J. Nap, Sung Hyun Park and Igal Szleifer

    Article first published online: 21 OCT 2014 | DOI: 10.1002/polb.23613

    A molecular theory was used to investigate the interactions between polyelectrolyte coated nanoparticles in aqueous solutions containing high amounts of salt. Design criteria were identified to achieve dispersion stability of nanoparticles coated with either polyacrylic acid, poly acrylamido-2-methylpropane sulfonate, or an alternating copolymer under brine-like conditions. The effects of nanoparticle core size, molecular weight, density of the polyelectrolyte coating, and polymer chemistry were quantified.

    Recent developments in interfacial engineering of conjugated polymer-semiconductor nanocrystal (CP-NC) nanocomposites has enabled intimate contact between CPs and NCs, thereby facilitating charge separation between these two constituents. This Review seeks to highlight recent advances in CP-NC nanocomposites for hybrid solar cells. Several strategies for hybrid solar cells with potentially improved device performance are discussed. An outlook for future research directions in this rich field is also presented.

    Janus hybrid hairy nanoparticles

    Tian Zhou, Bin Dong, Hao Qi, Shan Mei and Christopher Y. Li

    Article first published online: 13 OCT 2014 | DOI: 10.1002/polb.23611

    Janus hairy nanoparticles (JHNPs) represent a new class of hybrid materials with a nanoparticle core and a layer of bicompartmentalized polymer brushes. The unique combination of amphiphilicity, processibility, and optical/electrical/mechanical properties of these systems makes them well suited for a wide range of applications. This review summarizes the recent progress in the field, including fabrication approaches and self- and directed assembly behaviors of such JHNPs.

  4. Stretchable and flexible resistive behavior of poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate) thin film on ultra-low modulus polydimethylsiloxane with trench-type roughness

    Syed Murtuza Mehdi, Jeongdai Jo, Yang Hoi Doh, Hyun Woo Dang and Kyung Hyun Choi

    Article first published online: 10 OCT 2014 | DOI: 10.1002/polb.23615

    Conductive polymer poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) is becoming important in the field of organic electronics. Its performance as a conductive polymer under the action of tensile and bending loads on rough ultra-low modulus polydimethylsiloxane substrates has been investigated. The results suggest that the trench-type roughness pattern has positive influence on the performance of the conductive films during mechanical loadings owing to which the fabricated polymer–polymer laminate can have potential applications in stretchable and flexible organic electronics.
