A self-inflating hydrogel based on silk fibroin (SF) and poly(sodium acrylate) (PAAS) was synthesized by the free radical copolymerization. Furthermore, its potential as a tissue implant with minimally invasive treatment was investigated. The effects of the weight ratio of SF to AA (acrylic acid) on the structure, swelling properties and mechanical properties of the PAAS-SF semi-IPN hydrogels were investigated. In addition, the loading and release of amoxicillin of the PAAS-SF semi-IPN hydrogels were studied. With increasing SF content in the hydrogels, the swelling ratio and the rate of drug release increased, while the compressive strength decreased. It was observed that (83.4±0.9)% of the loaded drug was released within 120 h for the PAAS-SF20 semi-IPN hydrogels. The results revealed that the self-inflating PAAS-SF semi-IPN hydrogels with high swelling ratio and good drug releasing capabilities may have potential in the drug delivery or other implantable materials.
