Coupling Mechanical and Electrical Properties in Spin Crossover Polymer Composites
Sylvain Rat,Mario Piedrahita-Bello,Lionel Salmon,Gábor Molnár,Philippe Demont,Azzedine Bousseksou +5 more
TL;DR: Analysis of mechanical and dielectric properties reveals that both strain and permittivity changes in the composite accompany the spin transition in the particles, giving direct evidence for strong electromechanical couplings between the components.
