Poly(vinyl alcohol) cryogels: Effect size of polymer concentration, number of cycles and thawing rate on material properties and dermal drug delivery.

Poly(vinyl alcohol) (PVA) can be physically cross-linked by repeated freeze-thaw (F-T) cycles, resulting in a cryogel. Despite the growing prevalence of the cryogelation process in the scientific literature, its multivariable nature, particularly the…
