2.2.2. Impacts of structure design
The impact of different surface structures on hydrogels can lead to
variations in heat absorption,[53] moisture
retention,[54] wear resistance, etc. For
mechanical or wearable devices, the overall shape of the hydrogel can be
molded according to the specific needs of the device, facilitating
effective heat dissipation. Furthermore, to achieve an optimal
morphology, the microstructure of hydrogels should be intentionally
designed based on actual requirements.[54–59]
