Abstract

In this study, 3-methacryloxypropyltrimethoxysilane (MPS) was used to modify the surface of SiO₂ nanoparticles (SNPs) in order to obtain the vinyl-contained functionalized SNPs (F-SNPs). High strength poly (N-isopropylacrylamide) (PNIPA)/SiO₂ nanocomposite hydrogel (FS-NC gel) was prepared by in situ free radical polymerization of N-isopropyl acrylamide in the aqueous dispersion of F-SNPs. The results obtained from mechanical tests and swelling measurements indicate that the FS-NC gel displays significantly improved mechanical properties (the tensile and compressive strength of FS-NC gels are up to 205 kPa and 7.8 MPa, respectively) compared to hydrogels cross-linked with organic cross-linker or unmodified SNPs, and maintains the fast response rate and temperature-sensitivity of PNIPA nanocomposite hydrogels. Furthermore, FS-NC gel also shows water-induced shape memory behavior.
