ionomer cluster
Ionic aggregate, in a polymer matrix of low @[email protected], formed through interactions of @[email protected] multiplets.
  1. The @[email protected] of the polymer segments surrounding the multiplets is reduced relative to that of bulk material. With increasing ion content, the @[email protected] of the @[email protected] multiplets increases, leading to overlapping of the restricted @[email protected] regions around the multiplets and the formation of clusters.
  2. Typically, an @[email protected] exhibits two @[email protected] temperatures (\(T_{\text{g}}\)), one for the non-polar matrix and the other for clusters.
