      Cover: The cover image shows a temperature-controlled, cross-linking reaction of Matrimid with a diamine, resulting in a homogeneous solventgel. The background of the figure is a scanning image resolution image of the aerogel that has been obtained from the solventgel by solvent extraction with supercritical CO2. Further details can be found in the article by S. Kuiper, A. Embrechts, H. A. Every, T. de Vries, and L. C. P. M. de Smet* on page 868.

      Novel characteristics of nanofibers and their updated achievements in medicine, chemistry, and electronics are analyzed. With their high-surface-to-volume ratio, nanofibers help to enhance the interactions between the substrates and targets such as cells (in medicine), chemicals (chemical processes) and electrons (in electronics).

    1. Matrimid Aerogels by Temperature-Controlled, Solution-Based Crosslinking (pages 868–875)

      Stefan Kuiper, Anika Embrechts, Hayley A. Every, Tjerk de Vries and Louis C. P. M. de Smet

      Version of Record online: 13 DEC 2012 | DOI: 10.1002/mame.201200335

      By adding a solution with a crosslinking agent (diamine) to a preheated Matrimid solution, a homogenous mixture is prepared. Crosslinking only starts once the temperature is reduced. The resulting gels are studied by FTIR and AFM. Aerogels have been prepared successfully by supercritical CO2 extraction of the solvent and are further characterized via nitrogen adsorption studies and SEM.

    2. Structure and Rheological Behavior of Thermoreversible Supramolecular Polymers with Weak Multiple Hydrogen Bonds (pages 876–887)

      Supramolecular OPA-SUs are assembled by randomly branched oligomers with multiple hydrogen-bonding from amide sulfonylurea groups. The materials have reversible physical network structures with high rubber plateaus at room temperature and are yield stress fluid at around 90 °C. Tensile recovery tests demonstrate the supramolecular polymers show delayed rubber-elastic behavior.

    3. Compressible Magnetorheological Fluids Based on Composite Polyurethane Microspheres (pages 888–895)

      Compressible magnetorheological fluids (CMRFs) are prepared and characterized. The surfaces of iron particles are coated with fluorostyrene to provide dispersion stability. The viscoelastic properties improve drastically when magnetic fields are applied. The microspheres composite with polyurethane show a high compatible interface, are thermally stable, and mechanically robust.

    4. Plasticizing and Reinforcing Features of Siloxane Domains in Amine-Cured Epoxy/Silica Hybrids (pages 896–909)

      Filomena Piscitelli, Marino Lavorgna, Giovanna G. Buonocore, Letizia Verdolotti, Jocelyne Galy and Leno Mascia

      Version of Record online: 24 SEP 2012 | DOI: 10.1002/mame.201200222

      The properties of hybrid materials comprising an amine-epoxide network and polysiloxane inclusions depend on the fine control of crosslinking the and formation and segregation of the inorganic phase. In the presence of a highly reactive amine hardener, siloxane precursors give rise to plasticizing siloxane-epoxy linear sequences and reinforcing nanosized silica/silsesquioxane structures.

    5. Structure/Property Relationships of Partially Crosslinked Poly(butylene succinate) (pages 910–918)

      Commercially obtained PBS is partially crosslinked by using DCP as an initiator. The crosslinked PBS remains easily processable due to its low gel fraction and crosslink density. The overall crystallization rate of PBS is significantly increased, and the mechanical properties of PBS are significantly improved by the partial crosslinking.

    6. Fractional Crystallization Kinetics of Poly(ethylene oxide) in Its Blends with Poly(butylene succinate): Molecular Weight Effects (pages 919–927)

      Pengju Pan, Li Zhao and Yoshio Inoue

      Version of Record online: 19 SEP 2012 | DOI: 10.1002/mame.201200185

      The effects of MW on the fractional crystallization and phase distribution of a binary crystalline PBS/PEO blend is studied. The MW of PEO influences its fractional crystallization kinetics considerably. A medium MW of PEO facilitates fractional crystallization under supercooling conditions, likely ascribed to the segregation of PEO into the interlamellar region of PBS.
