Abstract
AbstractIn this work, metallic ions are introduced to polyacrylates to break the mutual limitation between damping peak width and height. It is found that all the ion‐coordinated polymers exhibit two loss peaks. With the increase of concentration, coordination strength, and steric hindrance, the temperature gap between two damping peaks can be broadened significantly while the peak height is slightly decreased. We are surprised to find that the effective damping temperature region (peak height ≥0.3) for poly (butyl acrylate) ionomers with 100% neutralization and weak coordination strength can be more than 200 K. Moreover, the damping peak area also increases after the introduction of metallic ions. Our result provides a new strategy for developing novel damping materials with high performance.
