Increased electromechanical sensitivity of polysiloxane elastomers by chemical modification with thioacetic groups

Yee Song Ko

Chemically cross-linked polydimethylsiloxane (PDMS) elastomers have gained importance as a dielectric in elastic capacitor actuators, which elongate when electrically charged. Common PDMS elastomers have a dielectric permittivity of only about 3 and thus e ...
