PAA/PVA IPN hydrogels were prepared by a sequential method by which acrylic acid firstly. polymerizes and cross-links in PVA/water solution with UV irradiation,then PVA physical cross-linked hydrogels are formed in cross-linked PAA networksby freezing-thawing. The orthogonal test design method was used to optimize theexperimental conditions based on the mechanical and swelling properties of thehydrogels. The effect of the PAA and crosslinking agent contents on the microscopicmorphology of the PAA/PVA IPN xerogel was investigated by transmission electronmicroscopy, and on the mechanical properties of the hydogels was studied bymeasurements of mechanical properties.
