Abstract:Salt acts as a plasticizer in polyelectrolyte complexes
(PECs),
which impacts the physical, thermal, and mechanical properties, thus
having implications in applications, such as drug delivery, energy
storage, and smart coatings. Added salt disrupts polycation–polyanion
intrinsic ion pairs, lowering a hydrated PEC’s glass transition
temperature (T
g). However, the relative
influence of counterion type on the PEC’s T
g is not well understood. Here, the effect of anion type
(NaCl, NaBr, NaNO3, and NaI) on the T
g… Show more
