Application

Poly(acrylic acid) partial sodium saltsolution(PAAPSS) can be used to fabricate humidity sensors as it is superhydrophilic in nature and allows the adsorption of the maximum number ofavailable water molecules onto the active layer. The addition of PAAPSSsignificantly increases sensitivity while maintaining stability.
