- Anisotropic Lithium Ion Conductivity in Single-Ion Diblock Copolymer Electrolyte Thin Films
Karim Aissou, Muhammad Mumtaz, Özlem Usluer, Gilles Pécastaings, Giuseppe Portale, Guillaume Fleury, Eric Cloutet and Georges Hadziioannou
Article first published online: 30 NOV 2015 | DOI: 10.1002/marc.201500562
Conductivity anisotropy ratio up to 1000 has been achieved from single-ion PS-b-PSLiTFSI thin films by comparing Li-ion conductivities of out-of-plane (aligned) and inplane (antialigned) cylinder morphologies at 40 °C. Results are also compared with PSLiTFSI homopolymer homologues, which reveal that ionic conductivity is improved when thin films are nanostructured.
- Modification Pathways for Copoly(2-oxazoline)s Enabling Their Application as Antireflective Coatings in Photolithography

Bottom antireflective coatings based on anthracene-functionalized crosslinkable copoly(2-oxazoline)s significantly enhance the resolution attainable with commercially available photoresists. Films of copoly(2-oxazoline)s with an anthracene content of 35%, which lower the amplitude of the swing-curve of photoresists by more than 50%, can be prepared by a combination of the Huisgen cycloaddition (functionalization with the chromophore) and the thiol-ene click reaction (crosslinking reaction).
- Temperature-Dependent Evolution of Poly(3-Hexylthiophene) Type-II Phase in a Blended Thin Film
Si Woo Lee, Hee-Sung Keum, Han Seong Kim, Hyo Jung Kim, Kwangseok Ahn, Dong Ryeol Lee, Je Han Kim and Hyun Hwi Lee

Type-II (or type II-like) P3HT phase is formed in P3HT:PCBM films on a poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) substrate by cryogenic cooling to low temperature (−143 °C) followed by gradual heating to room temperature. The formation of type-II P3HT was largely enhanced by the presence of the upper Al electrode layer. Concomitant with the formation of the type-II phase, a 1:3 ordered P3HT type-II (1/3,0,0) superlattice peak emerges.
- Radical Chain Polymerization Catalyzed by Graphene Oxide and Cooperative Hydrogen Bonding
Zhongcheng Zhu, Shengjie Shi and Huiliang Wang
Article first published online: 25 NOV 2015 | DOI: 10.1002/marc.201500573
Graphene oxide (GO) can function as a catalyst to accelerate the radical chain polymerizations of acrylic acid (AA), as indicated by the much enhanced overall kinetic rate constants and lowered activation energies. The catalytic effect of GO for the polymerization of AA is due to the acidic nature of GO and the hydrogen bonding interactions between GO and monomer molecules and/or polymers.
- Single-Chain Folding of Synthetic Polymers: A Critical Update
Ozcan Altintas and Christopher Barner-Kowollik
Article first published online: 23 NOV 2015 | DOI: 10.1002/marc.201500547
The synthesis and characterization of single-chain nanoparticles based on well-defined functional linear synthetic macromolecules via selective point folding as well as repeat unit folding are critically discussed via selected recent examples.
