The SEM images in Figure , taken from the cross-sectional area of freeze-dried samples, provide a clear view of the microstructural impact of methacrylation on the hydrogels. Freezedrying removes water content to expose the polymer network, revealing differences in pore structure stability across methacrylation levels. In low and medium methacrylation hydrogels, the pore walls appear thin and collapsed, with indistinct and irregular boundaries. This structural weakness likely results from insufficient crosslinking, which fails to support the pore walls during the freeze-drying process, causing them to shrink and lose their form. The reduced wall thickness and partially collapsed pores indicate a less stable network with limited mechanical integrity. Conversely, hydrogels with higher methacrylation display a wellpreserved, open porous structure with defined, thick pore walls. This intact network reflects strong crosslinking, allowing the hydrogel to maintain its structure under freeze-drying conditions. The prominent pore walls and uniform porosity in the highly methacrylated samples indicate robust structural stability and integrity.
