Morphology of Amphiphilic Diblock Copolypeptide Hydrogels Determined by Ultra-small Angle Neutron Scattering

摘要

Hydrogels are chemically or physically crosslinked networks of hydrophilic polymer chains that are able to absorb large volumes of water. The interactions of crosslink points within the polymer network create a materials that is porous on the nanoscale. Higher orders of porosity are added to hydrogels through various processing techniques including freeze-thaw and salt leaching.
