CONDUCTING HYDROGELS

On page 864, Holly Warren, Reece D. Gately, Patrick O’Brien, Robert Gorkin III, and Marc

in het Panhuis report the impedance method allows for percolation analysis, which

determines when the conducting hydrogels transition from transport dominated by

ions (due to the biopolymer) to electrons (due to carbon fillers).

POLYKETONES

Evaporating 1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) from a polyketone/HFIP solution

leads to a porous cast-film with a microparticle structure. This is due to the isotactic poly-

ketones adopting a helical conformation and to convection during evaporation of the

highly polar and volatile HFIP causing aggregation and rolling of the polymer molecules.

Plasticizer addition suppresses particle formation, improving the surface structure and

mechanical properties of the film. In particular, the dielectric properties of the film

improve significantly. This will enable polyketones, which are rigid insulating materials,

to be used as dielectric materials, thus broadening their range of applications.
