Superabsorbent polymers (SAPs) are used in various fields due to their ability of absorbing and retain large volumes of water and aqueous solutions. However, gel blocking of SAP is disturbing its uses, and there have been continuous efforts to improve gel blocking of SAP. The most conventional approach is crosslinking of SAPs surface. In this study, we used poly(itaconic acid) based SAP particles as a core SAP and coated the core SAP with porous and hydrophobic silica aerogel to prevent the gel blocking of the core SAP particles. The process was affected by many processing parameters like concentration of silica aerogel, and amount of water, indicating all the variables need to be finely tuned to maximize the efficiency of the SAP. |
