Polymer light-emitting electrochemical cells (PLEC) are photonic devices that function by in situ electrochemical doping for luminescent polymers. Doping in PLECs is achieved via electrically activated redox reactions in the presence of mobile counter-ions. In operation, p- and n- doping fronts form at the anode and the cathode. The fronts then propagate through the polymer film and form a p-n...

We study the electrical and mechanical properties of poly(ethylene oxide)/multiwalled carbon
nanotube (PEO/MWCNT) composites made by melt mixing and compression molding. The dielec-
tric properties of the PEO/MWCNT composites have been studied in the frequency range from
100 mHz to 1 MHz as a function of temperature and ?ller concentration. Dielectric relaxation
times and DC conductivity were...

Diblock copolymers are composed of two chemically distinct homopolymers, covalently bound end-to-end. One of the most notable features of block copolymers is their ability to self-assembly into a wide range of ordered periodic structures. There are many factors affecting the equilibrium morphology of diblock copolymers, one of which is polydispersity. The rich phase behaviour of polydispersed...

Invited Speaker / Conférencier invité

The ability of a feed-forward neural network to learn and classify different states of polymer configurations is systematically explored. Performing numerical experiments, we find that a simple network model can, after adequate training, recognize multiple structures, including gas-like coil, liquid-like globular, and crystalline anti-Mackay and Mackay structures produced from Monte Carlo...
