- Soluble reduced graphene oxide functionalized with conjugated polymer for heterojunction solar cells

Article first published online: 10 FEB 2012 | DOI: 10.1002/pola.25948
A solution-processable conjugated polymer PCTF-convalently grafted reduced graphene oxide (PCTF-RGO) was synthesized by the 1,3-dipolar cycloaddition of azomethine ylide. The short-circuit current density and power conversion efficiency of a photovoltaic device based on the spin-coated PCTF-RGO/[70]PCBM heterostructure reached 260 and 145 times higher than those of the device without [70]PCBM, respectively.

Article first published online: 10 FEB 2012 | DOI: 10.1002/pola.25947
The study investigates the degradation behavior of various high molecular weight acrylic polymers namely poly(methyl methacrylate) (PMMA), poly(n-butyl methacrylate) (PBMA), poly(n-butyl acrylate) (PBA) and poly(lauryl methacrylate) (PLMA) under extreme environmental conditions via X-ray photoelectron spectroscopy and high resolution FTIR microscopy imaging.
- Poly(ethylene glycol)–poly(L-lactide) star block copolymer hydrogels crosslinked by metal–ligand coordination
Sytze J. Buwalda, Pieter J. Dijkstra and Jan Feijen
Article first published online: 10 FEB 2012 | DOI: 10.1002/pola.25945
In aqueous solutions, pyridine-end-functionalized poly(ethylene glycol)–poly(L-lactide) star block copolymers self-assemble into micelles and micellar aggregates at low concentrations and form physically crosslinked, thermoreversible hydrogels above a critical gel concentration of 8% w/v. The presence of Mn(II) ions results in increased aggregate dimensions, a larger gel window, and increased in vitro stability due to the coordination of pyridine ligands around the metal centers, thereby introducing additional crosslinks. Importantly, the stabilizing effect of metal–ligand coordination is noticeable at very low, nontoxic metal ion concentrations.
