Poly(3-hexylthiophene) (P3HT) nanowires are prepared by the whisker method. After thermal or solvent annealing, the crystallinities of the P3HT nanowires increase, as confirmed by differential scanning calorimetry and X-ray diffraction. The device performances of organic field-effect transistors based on the annealed nanowires are also examined, and the charge mobility increases by one order after annealing.

Polynorbornenes with an allyl acetate end group are prepared by Ru-catalyzed ring-opening metathesis polymerization. In the presence of a Pd-catalyst, the allyl acetate is replaced by a range of different nucleophiles. Polymer with the phosphonate end group is imobilized onto an indium tin oxide (ITO) electrode and the electrochemical properties of this modified electrode are perturbed.
- The Interaction Between Amphiphilic Polymer Materials and Guest Molecules: Selective Adsorption and Its Related Applications

Amphiphilic polymer materials possess selective adsorption to guest molecules, such as dyes, drugs, proteins, and other biomolecules, which is beneficial for their application in the separation, temporally controlled release, and patterning of guest molecules.
- Surface Morphology, Crystallinity, and Hydrophilicity of Poly(ε-caprolactone) Films Prepared Via Casting of Ethyl Lactate and Ethyl Acetate Solutions
Andrea Causa, Giovanni Filippone, Domenico Acierno, Concepción Domingo and Aurelio Salerno

Films of semicrystalline biodegradable poly(ε-caprolactone) (PCL) are fabricated by a fully biobased drop-casting route. It is reported that by the appropriate selection of polymer concentration and solvent type, it is possible to achieve a fine control over the film's morphology and texture and, ultimately, to tune the film hydrophilicity.
- From Old to New: Polymers from Mono-α-Alkylated N-vinylcaprolactam
Lisa Schönenberg and Helmut Ritter
Article first published online: 2 OCT 2014 | DOI: 10.1002/macp.201400376
A group of new N-vinylcaprolactam derivatives is synthesized via nucleophilic substitution at the α-carbon atom of the lactam ring. Homo- and copolymerization of those derivatives is performed by the free-radical mechanism and the basic characteristics of the obtained structures, such as molecular weight, glass-transition temperature, and copolymer composition, are investigated.
