- Suppressing the environmental dependence of the open-circuit voltage in inverted polymer solar cells through a radical polymer anodic modifier
Lizbeth Rostro, Lucio Galicia and Bryan W. Boudouris
Article first published online: 25 NOV 2014 | DOI: 10.1002/polb.23640
The transparent radical polymer, poly(2,2,6,6-tetramethylpiperidinyloxy methacrylate) (PTMA), serves as the anodic modifier in inverted geometry organic photovoltaic (OPV) devices. The incorporation of this macromolecular modifying layer enhances the performance of the OPVs over those devices that did not have an anodic modifier. Importantly, devices fabricated with the PTMA interlayer remained stable over the entire course of multi-day testing after being exposed to ambient conditions.
- XPS and resistive studies on thin films of a copper(II)-based coordination polymer deposited on functionalized interdigital electrodes

Article first published online: 24 NOV 2014 | DOI: 10.1002/polb.23633
The preparation of self-assembled monolayers on the surface of a transducer is studied by XPS measurements. The selective deposition of a new organic molecule based on 2-mercaptopyrimidine on gold electrodes and the simultaneous coating of the silicon dioxide substrate with a 3-mercaptopropylsilane are described. Thin layers of a copper(II) based coordination polymer functionalizes the electrodes and sensor-like behavior is demonstrated by resistive measurements.
- Dynamics of cyclodimerization and viscoelasticity of photo-crosslinkable PVA
Huiyu Bai, Jing Xu, Yanxia Zhang, Xiaoya Liu and Orlando J. Rojas
Article first published online: 24 NOV 2014 | DOI: 10.1002/polb.23634
The extent and dynamics of poly(vinyl alcohol) carrying UV-crosslinkable pendant quaternized stilbazole (styrylpyridinium) cyclodimerization reactions and crosslinking induced by UV irradiation were monitored in situ and in real time by quartz crystal microgravimetry (QCM). The shifts in QCM frequency and energy dissipation upon PVA-SbQ cyclodimerization correlated with three photo-crosslinking phases involving soft-to-rigid transitions, namely, induction (initiation), main crosslinking (interaction), and termination. PVA-SbQ films crosslinked to different degrees were used as carrier of bovine serum albumin.
- Effect of dispersion and selective localization of carbon nanotubes on rheology and electrical conductivity of polyamide 6 (PA6), Polypropylene (PP), and PA6/PP nanocomposites

Addition of carbon nanotubes can improve the mechanical and electrical properties of polymers. In this study, rheologic and electrical properties of PA6, PP, and their co-continuous blends of 60/40 and 50/50 volume compositions were studied with a focus on the effect of dispersion, distribution, and localization of nanotubes. Because of the localization of carbon nanotubes in the PA6 phase and their higher effective concentration, blend nanocomposites had much higher electrical conductivity compared with that of neat PA6.
- Self-assembled graphene oxide–gelatin nanocomposite hydrogels: Characterization, formation mechanisms, and pH-sensitive drug release behavior
Yongzhe Piao and Biqiong Chen
Article first published online: 24 NOV 2014 | DOI: 10.1002/polb.23636
Physically crosslinked graphene oxide–gelatin nanocomposite hydrogels were synthesized by self-assembly without using a toxic organic crosslinker. The static and dynamic rheological properties of the hydrogels are investigated. The multiple crosslinking sites on each graphene oxide nanosheet and gelatin chain endow the hydrogels with high mechanical performance, with a storage modulus up to 114.5 kPa. The hydrogels are pH-sensitive, undergoing reversible sol–gel transitions, and exhibiting pH-controlled drug release behavior.
