- Effect of the C/O ratio in graphene oxide materials on the reinforcement of epoxy-based nanocomposites
Cristina Vallés, Fabian Beckert, Laura Burk, Rolf Mülhaupt, Robert J. Young and Ian A. Kinloch
Article first published online: 6 OCT 2015 | DOI: 10.1002/polb.23925
It has been demonstrated that both graphene oxide (GO) and thermally-reduced graphene oxide (TRGO) are found to reinforce epoxy-based nanocomposites. The Young's modulus of the GO in the nanocomposites was found to be around 170 GPa and this reduced to 120 GPa for the TRGO. The addition of GO to the polymer was not found to increase the viscosity of the epoxy significantly such that the resulting materials were found to have a good combination of processability and mechanical properties.
- Where the rubber meets the hand: Unlocking the sensing potential of dielectric elastomers

Article first published online: 6 OCT 2015 | DOI: 10.1002/polb.23926
Softer touch interfaces pave the way for a more natural contact with the human body. Dielectric elastomer (DE) sensors were constructed into a musical keyboard, demonstrating a new sensing method that is able to detect localized changes in the sensor's capacitance. This allows different regions of the DE to be used as independent sensors, achieving improved scalability and simplification for multidegree of freedom systems.
- The influence of short-chain branching on the morphology and structure of polyethylene single crystals

The effect of short chain branching on the morphology and structure of polyethylene single crystals is investigated. For the first time, the presence of chain defects is observed to cause curved (110) faces in single crystals in high molecular weight polyethylene. The curvature is explained within the Shcherbina and Ungar model for asymmetric growth faces, as a consequence of an increase in the initiation step propagation ratio of the crystallization process as the amount of chain defects increases.
- Focused laser-induced marangoni dewetting for patterning polymer thin films
Jonathan P. Singer, Steven E. Kooi and Edwin L. Thomas
Article first published online: 5 OCT 2015 | DOI: 10.1002/polb.23906
An investigation of the effect of various experimental parameters reveals that the focus laser spike (FLaSk)-induced thermocapillary dewetting of polymer thin films patterns lines whose profile shapes depend mainly on the high temperature melt mobility (related to molecular weight) and the film thickness (related to antireflection effects) of the polymer. This allows for generalized processing of multiple materials systems. In addition, bilayer mobility and use of solvent swelling lead to other profile variations, namely segmented and “flat-topped” line patterns.
- Dynamic rheology and relaxation time spectra of oil-based self-degradable gels
Oscar Vernáez, Sylvie Dagreou, Bruno Grassl and Alejandro J. Müller
Article first published online: 5 OCT 2015 | DOI: 10.1002/polb.23918
A self-degradable gel system designed to be used as a diverting agent in oil well operations has been characterized by oscillatory rheometry. Structural changes in the polymer network were visible within the relaxation time spectra. Rheological properties were evaluated as a function of peroxide, polymer, hydroperoxide, and a hydrogen donor concentration as well as a function of the temperature.
