There are still several basic issues regarding PVA cryogels that deserve further
investigation, especially related to the complex dynamics of water molecules and
polymer chains. The identification of smart processing routes to obtain systems
with tailored pore size and pore size distribution, and with well-defined viscoelastic
properties, is critically dependent on fundamental study of the dynamics of these
systems, coupled with modeling.
