摘要

In this work, inorganic nanoparticle reinforced glucuronoxylan-based hydrophobic association hydrogels were prepared. Nano-ZnO, nano-SiO2, nano-CuO, nano-Al2O3, and nano-TiO2 were used to improve the compressive strength of the hydrogels. The FT-IR, SEM and XPS were used to investigate the properties of the hydrogels. The maximum compressive strength of the nano-ZnO, nano-SiO2, nano-CuO, nano-Al2O3, and nano-TiO2 reinforced hydrogels were 16.55 MPa, 19.48 MPa, 16.33 MPa, 20.58 MPa and 17.83 MPa. The addition of nanoparticles made the hydrogel have high degradation temperature (~ 230 °C). The species of nanoparticles have significant effects on compressive strength and swelling ratio (SR). Furthermore, the nanoscale of ZnO also have impacts on the properties of the hydrogels. With the decrease of ZnO particle sizes, the mechanical properties and antibacterial properties were all improved. The hydrogels with 30 nm nano-ZnO had the highest compressive strength (14.43–16.55 MPa) and the best antibacterial properties. In addition, almost all the cell viability values of nano-ZnO reinforced hydrogels were higher than 85%. These results suggested that the ZnO nanoparticles were non-toxic and the hydrogels could be safely used in biological medicine.
