- Borderline Particles: Approaching the Limit between Colloidal Stability and Instability during Heterophase Polymerization
Ran Yu, Eddie Peh, Liliia Mavliutova, Nancy Weber and Klaus Tauer
Article first published online: 5 FEB 2016 | DOI: 10.1002/macp.201500441
The experimental conditions for the formation of a new morphology of colloidal polymer particles by aqueous heterophase polymerization – multiple suspension particles– are reported. These particles consist of block copolymers which are arranged in form of a µm-sized poly(N-isopropyl acrylamide) physical network as scaffold containing nm-sized particles of hydrophobic polymers covalently attached.
- Tuning the Surface Properties of Polypyrrole Films for Modulating Bacterial Adhesion
Mohsen Golabi, Anthony P. F. Turner and Edwin W. H. Jager

Polypyrrole (PPy) is electrochemically synthesized under various conditions with different types of dopants to tune the surface properties of the film including roughness and hydrophobicity. The polymer surface properties show a significant effect on the bacterial adhesion to the surface. The results may guide choosing suitable polymer synthesis conditions to yield PPy with suitable surface properties for the intended application.
- Synthesis and Thermal Characterization of Precision Poly(p-cyclohexylene alkylene)s via Acyclic Diene Metathesis Polycondensation
Lucas Caire da Silva and Kenneth B. Wagener
Article first published online: 5 FEB 2016 | DOI: 10.1002/macp.201500508
Poly(p-cyclohexylene alkylene)s with 1,4-cyclohexylene units precisely placed at every 15th, 19th, and 21st chain carbon are synthesized via acyclic diene metathesis polycondensation. The fully saturated polymers show excellent thermal stability and enhanced thermal behavior conferred by the flexibility of the 1,4-cyclohexylene units.
- Aqueous Photoelectrochemical Reduction of Anthraquinone Disulfonate at Organic Polymer Films
Pankaj Chowdhury, Patrick Fortin, Graeme Suppes and Steven Holdcroft
Article first published online: 4 FEB 2016 | DOI: 10.1002/macp.201500440
Poly(3-hexylthiophene) (P3HT), an organic, p-type semiconductor, is widely studied in the organic field-effect transistors, organic light-emitting diodes, and organic photovoltaics; but little is known about its potential to harness visible light energy via photoelectrochemical processes. The energetics and photoreduction of an anthraquinone-based redox couple in aqueous solution are described.
- Design of Piperazine Organoiron Macromolecules with Antibacterial and Anticancer Activity
Alaa S. Abd-El-Aziz, Amani A. Abdelghani, Jason K. Pearson, Mohamed K. Awad, David P. Overy and Russell G. Kerr
Article first published online: 4 FEB 2016 | DOI: 10.1002/macp.201500489
Piperazine–organoiron macromolecules are prepared. These macromolecules exhibit good thermal stability as well as antibacterial and anticancer activity. The Merck molecular force field is used for molecular mechanics modeling of the series of complexes and all conformers show similar energies and flexible structures.
