Designing Superabsorbent Polymers for Rapid Water Absorption through Microparticle Assembly after Inverse Suspension Polymerization: Examining Capillary Diffusion as a Driving Force.

ABSTRACT: Manufacturers employ inverse suspension polymerization to increase water absorption and absorption under the pressure of superabsorbent polymers (SAPs) used in personal hygiene products. Researchers have primarily focused on maximizing the water absorption capacity of SAPs when saturated, often by maximizing the swelling ratio. However, there is a scarcity of literature addressing the fast absorption properties necessary for user comfort and dryness in real-world applications. In this study, we assembled PAA-based SAP microparticles in two different sizes to produce a novel capillary diffusion effect, aimed at enhancing water retention capacity after 1 min of absorption (RCW-1), capable of absorbing more water before swelling. We prepared 30-40 μm SAP microparticles (SAP-1), showing high R
