- Nanocomposite hydrogels: Fracture toughness and energy dissipation mechanisms
Andrea Klein, Philip G. Whitten, Katharina Resch and Gerald Pinter
Article first published online: 8 OCT 2015 | DOI: 10.1002/polb.23912
The fracture energy of poly(N,N-dimethylacrylamide)-Laponite XLS nanocomposite hydrogels was quantified by the pure shear test to be up to 6800 J m−2, the second highest reported for a hydrogel. Crack tip blunting, plastic deformation, and viscoelastic dissipation cooperate to achieve extraordinary high fracture energies.
- Retardation of shape change of Au nanorods using photo-cross-linkable ligands

Article first published online: 8 OCT 2015 | DOI: 10.1002/polb.23929
The retardation of thermal reshaping of gold nanorods by grafting a diblock copolymer [P(S-b-S-N3)] containing an outer polystyrene (PS) brush and a short, inner photo-cross-linkable PS-azide block is reported. The P(S-b-S-N3)-Au NRs are dispersed in a PS thin film and reshaping is investigated using scanning electron microscopy and UV–Vis spectroscopy. By slowing down reshaping at elevated temperature, polymer thin film devices that heat during use can exhibit a longer lifetime.

Ion gels comprising ABA brush block copolymers and 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMI][TFSI]) are reported. Structure and conductivity measurements reveal trends in gel properties as a function of block volume fraction, polymer molar mass, and concentration. Conductivities near 1 mS/cm at 25 °C and normalized conductivities 0.2 to 0.8 highlight liquid-like dynamics in the matrix phase and potentially presage future applications.
- 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
Daniel Xu, Andreas Tairych and Iain A. Anderson
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.
