    A new concept for the design of organic ferroelectric diodes is explored based on combining the ferroelectric benzene-tricarboxamide (BTA) core with pyrrole groups, which can be polymerized to provide a semiconducting ferroelectric material. At high frequencies, the compound exhibits clear ferroelectric switching behavior, while at low frequencies, extremely high hysteretic charge density is measured, which is ascribed to electrochemical polymerization of pyrrole groups enabled by the presence of amide groups.

    Poly(vinyl butyral) serves as a powerful nucleating agent for a series of poly(butylene succinate-co-terephthalate) biopolyesters. The peak temperature of crystallization increases by 28 °C at 0.3 wt % PVB incorporated for PBST with 50 mol % terephthalic acid. The molecular structure of PVB is mainly responsible for this significant effect of nucleation, together with its chain mobility in crystallization.

  3. Tuning hydrophobicity of a fluorinated terpolymer in differently assembled thin films

    Thin films of fluorinated terpolymer of THV prepared by casting from good solvent yielded smooth morphology, versus films prepared by casting from mixed solvent and nonsolvent yielding spheres and dense layers. In comparison to casting from good solvent, hydrophobicity of THV increased by approximately 43% on the thin films cast with mixed solvent and non-solvent.

    Polymer strategies in perovskite solar cells

    Anna Isakova and Paul D. Topham

    Version of Record online: 7 FEB 2017 | DOI: 10.1002/polb.24301

    Perovskite solar cells have achieved remarkable efficiencies in only four years due to extensive employment of polymeric strategies, adopted from organic photovoltaic (OPV) and organic light-emitting diode (OLED) research. This review summarises various approaches of incorporating polymers in perovskite devices, from charge transport layers to templating agents for the perovskite layer, and how they serve to solve the problems of stability and J-V hysteresis.

  5. Phase separation kinetics in unentangled polymer solutions under high-rate extension

    Flow-induced phase separation in polymer solutions under high-rate extension is a hierarchical process involving multiple length and time scales. The process includes formation of protofibrils by anisotropic spinodal decomposition, development of long stiff fibrils forming a highly oriented network, and further microphase separation and lateral collapse of the network.
