Flexible new polymer may replace toxic plastics in smart devices

Scientists at Case Western Reserve University have developed a novel fluorine-free ferroelectric polymer that promises to replace environmentally harmful plastics commonly used in electronics, such as poly(vinylidene fluoride) (PVDF), a persistent “forever chemical.” Led by Professor Lei Zhu, the team created a flexible, rubber-like material that generates electric properties without requiring crystallization, unlike traditional ferroelectric materials. This innovation offers tunable electrical characteristics, improved manufacturability into thin films or coatings, and acoustic compatibility with biological tissue, making it particularly suitable for wearable medical sensors, virtual and augmented reality devices, and other smart electronics. The new polymer addresses key limitations of existing ferroelectric materials, which are often brittle ceramics, by combining flexibility, lightness, and environmental safety. Although still in the development phase with small-scale synthesis underway, the material’s potential to reduce toxicity and waste in electronics is significant.
