Periodic Reporting for period 2 - TRANS (Synthesis of novel stimuli responsive dielectric polymers and their use in powerful transducers)
Período documentado: 2022-11-01 hasta 2024-04-30
This ERC CoG will build a strong multidisciplinary group concentrating on synthesizing novel functional dielectric polymers that are printed into devices capable of converting one form of energy into another. Research spans from materials synthesis and optimization via device engineering to the exploration of manifold applications. TRANS develops novel high-dielectric permittivity and piezoelectric elastomers with unprecedented properties and uses them as active components in devices for emerging technologies. The devices are of high technological and scientific importance and exhibit substantial economic and societal impact. They reversibly change their shape in response to an electric field, generate electricity when mechanically stretched, cool while using little energy, convert thermal energy directly into electricity and, finally, store electricity in the form of batteries. The polymers developed in TRANS combine either unprecedentedly high dielectric permittivity with a high dielectric breakdown field or piezoelectric properties with high elasticity. They can potentially revolutionize different fields of applications, such as actuators, sensors, energy harvesting, artificial muscles, soft robotics, energy storage, stretchable electronics, and solid-state refrigeration. A particularly important aspect concerns the synthesis of scalable, environmentally friendly, easy-to-apply, and processed printable inks, which are the active ingredients of various devices.
Results achieved during this project were published in open-access journals. Additionally, the results were presented at different conferences.

While a limited number of light-emitting capacitive devices with electroluminescence similar to our materials have been reported, our devices demonstrate clear superiority in that the matrix is fluorine-free and thus environmentally friendly.
Polysiloxane functionalized with thiopropionitrile proved to be very useful in solid-state Li-ion batteries.
An unexpected outcome emerged with the self-segregation of bottlebrush polymers carrying PDMS side chains and a polar group on the polynorbornene backbone, resulting in free-standing films upon solution casting. We are excited about this discovery because it holds the potential for designing new dielectric materials with tunable properties.
After project termination, the group will expand the fundamental understanding of the relationship between structure and dielectric properties. It will be able to provide inks printed in prototype devices that are responsive to electricity, heat, or mechanical stress as well as a polymer solid electrolyte for Li-ion batteries.
