Different concentrations of silver nanowires were absorbed into superabsorbent materials and the effect of silver nanowires concentration on swelling ratios, swelling rate and antibacterial behaviors were investigated in this study. In addition, comparison of antibacterial experiment of xerogel and wet gel and silver nanoparticles and silver nanowires were carried out and the results also showed that xerogels containing silver nanowires had better antibacterial effect, and silver nanoparticles had better antibacterial effect. The antibacterial behaviors of superabsorbent materials containing silver nanowires could also be proved by observation of surface distribution of silver nanowires via SEM. PART 2 Abstract In this study, aminophthalyl hydrazide (Luminol) was acrylated by acryloyl chloride to prepare acrylamidophthalyl hydrazide (acryl luminol, ALU) monomer, then poly(Acryl Luminol) (PALU) was prepared by free radical polymerization. The chemiluminescence intensity of the luminol monomer and PALU was compared. In addition, a series of copolymeric hydrogels were prepared from 2-hydroxyethyl methacrylate (HEMA) and ALU. Their optical behavior and physical properties were investigated. The results showed that chemiluminescence intensities of PALU and ALU are weaker than the original luminol. In addition, the water content and gel strength of the poly(HEMA-co-ALU) copolymeric hydrogel decrease with the increase of ALU content. The chemiluminescence intensities of the poly(HEMA-co-ALU) copolymeric hydrogels are not obvious.
