With increasing blending time, particle size decreased, as observed with scale bars for 1 min and 2 min set at 500 µm, 3 min at 250 µm, and 4 min and 5 min at 200 µm. These images confirm that extended blending leads to finer microparticles, supporting the selection of optimal parameters for achieving the desired particle size for incorporation into composite hydrogels. Although there are some differences in pore size, the variation across compositions is subtle, indicating that changes in MPG ratios produce only minor adjustments in pore size. The MPG hydrogel, with larger average pore sizes between 50 µm and 100 µm, exhibits a loosely crosslinked network that supports high swelling capacity but may compromise mechanical integrity. In contrast, MFG hydrogels have smaller pore sizes (~60 µm), suggesting a more compact and densely crosslinked structure that limits swelling but enhances compressive strength. Composite hydrogels, such as those with 3:7 and 5:5 ratios, display intermediate pore sizes, but overall, no strong trend is observed, implying that the effect of MPG ratio on pore size is limited. These results suggest that while varying the MPG composition slightly affects pore size and porosity, the overall trend remains small, indicating a minor influence on microstructural features. Nevertheless, MPG-rich hydrogels with larger pores and higher porosity support increased water absorption, while MFG-rich hydrogels with smaller pores offer structural stability. These insights guide the design of hydrogels for specific biomedical applications, where the balance between swelling capacity and mechanical integrity is key, such as in tissue engineering scaffolds and drug delivery systems.
