Modulation of Thermal and Dielectric Properties in Poly(acrylonitrile‐co‐vinyl ether)s via Alkyl Side‐Chain Length Variation
The chemical structure of a polymer matrix fundamentally governs its macroscopic thermal, mechanical, and dielectric performance. High dielectric permittivity ( ε′$\varepsilon '$ ) polymers are essential for transducers, and introducing strongly polar nitrile groups effectively elevates ε′$\varepsilon '$ . However, sta...
