      Electroless deposition is a scalable, low-cost technique for coating textiles. In the work by Ligia Frunza, Nicoleta Preda, Elena Matei, Stefan Frunza, Constantin Paul Ganea, Aurel Mihai Vlaicu, Lucian Diamandescu, and Angela Dorogan on page on page 1427, polyester textiles are successfully coated with zinc oxide (ZnO) crystallites using an electroless deposition process, and results are compared to ZnO coated polyamide, poly(lactic acid), and hemp textiles. The fibers are homogeneously covered by ZnO hexagonal prisms having 20–500 nm in diameter and up to 1 lm in length. The resulting ZnO-coated polyester textiles are superhydrophobic with contact angles exceeding 150°.

      In a lamellar-forming block copolymer thin film, each lamellar thickness plays an important role in one-dimensional applications such as lithography techniques used to form line patterns. Here, binary blends of poly(styrene-b-methyl methacrylate) block copolymers where the lamellar thickness of one domain is controllable while preserving the thickness of the other domain were demonstrated in well-behaved, perpendicularly oriented thin films without microphase separation.

    1. Influence of the bridging atom in fluorene analogue low-bandgap polymers on photophysical and morphological properties of copper indium sulfide/polymer nanocomposite solar cells (pages 1400–1410)

      In the last decade organic photovoltaics have attracted considerable attention within the research community and industry due to their potential advantages over inorganic solar cells, including low cost, lightweight, and roll-to-roll processability on flexible substrates. As an alternative and promising technology for thin film photovoltaic applications, nanocomposite solar cells have emerged. Herein, detailed analyses of the interplay between polymer structure, nanomorphology, and device performance for copper indium sulfide/polymer nanocomposite solar cells are presented.

    2. Hairpin polymer unfolding in square nanochannels (pages 1411–1418)

      Chromosome bacteria segregation in biological nanopores is a fundamental process driven by entropic forces in confinement; it has been found that the unfolding dynamics of a hairpin DNA polymer in a solid-state nanochannel follow the same separation mechanisms. The confinement speeds up the unfolding process as reported in videomicroscopy experimental results; this trend is predicted by scaling theories and confirmed by using Brownian dyanamics simulations.

    3. Pattern replication in blends of semiconducting and insulating polymers casted by horizontal dipping (pages 1419–1426)

      Pattern replication in thin films made of mixtures of insulating and conjugated polymers might provide an alternative to other printing techniques for fabrication of polymer-based circuitries. Here, self-assembly of phase domains in a mixture of poly(3,3′′′-didodecyl quarter thiophene) and poly(styrene-co-4-bromostyrene), which was deposited by horizontal dipping on patterned substrates, shows that desired structures can be produced in a simple, high-throughput technological process. A variety of casting conditions for accomplishing pattern replication can be efficiently tested using variable thickness gradient samples.

      Thermally induced phase separation (TIPS) is a useful process to fabricate microporous polymer membranes with diverse morphologies. Different polymer diluents can lead to different porous structures for membranes composed of various crystalline forms of a semi-crystalline polymer, which determine the separation performance and mechanical strength of the membranes. In this work, the membrane morphology and phase separation mechanism of poly(vinylidene fluoride) (PVDF) membranes using cyclohexanone (CO) and propylene carbonate (PC) as diluents are studied.

    6. Polyaniline-tailored electromechanical responses of the silver/epoxy conductive adhesive composites (pages 1448–1455)

      Electrically conductive adhesives (ECAs) find extensive applications as interconnect materials for device assembly to meet the increasing demand of miniaturization of electronic products and portable devices. However, ECA bonds suffer from a relatively poor reliability in comparison with conventional soldering and wire bonding. In this work, polyaniline is investigated as a cofiller in silver-filled epoxy in both partially cured and fully cured states, providing insights into the establishment of a conductive network and the role of polyaniline in tailoring the electromechanical response of the ECAs.
