“…3,5,[9][10][11][12][13] and also as materials of biomedical interest, e.g., gels for controlled drug release, covers on wounds and burns, artificial cartilages, components of model heart implants, phantoms for calibration of NMR tomographs, and ultrasound equipment. [1][2][3][4][5][14][15][16][17][18] Along with PVACGs originating simply from the polymer solutions without any additives, complex and filled (composite) PVA cryogels were prepared, investigated, and described. 3,5,12 The former contain various soluble compounds, both of low-and highmolecular weight, whereas the latter include such dispersed matter, as solid particles, semi-solid gel granules, microbial cells, air bubbles, etc., entrapped (immobilized) in the matrix of continuous phasemacroporous PVA cryogel.…”
