Hydrogels tend to swell in underwater environments,leading to the deterioration of mechanical and electrical conductivity properties.Hydrophobic microphase separation stabilizes hydrogel networks and suppresses swelling by inducing the aggregation of hydrophobic segments into nanodomains.This review summarized key construction strategies,including copolymerization with hydrophobic monomers,amphiphilic self-assembly,double-network design,surface hydrophobization,and nanocomposite formation,and highlighted recent progress and remaining challenges in underwater wearable motion sensing applications.
