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.
