The development of hydrogels combining superior mechanical property attracts researchers' attention in recent years. Here, a novel nanocomposite hydrogel is prepared by one‐step photo‐polymerization acrylic acid (AA) and N,N‐dimethylacrylamide (DMAA) the presence hydroxyapatite nanoparticles (HAp NPs) aluminum hydroxide (Al(OH) 3 NPs). resulting transparent exhibits ultrahigh toughness 28.3 MJ m −3 , high strength 2.8 MPa, large elongation 1300%, excellent self‐recovery good...
Efficient up and down frequency conversions in Tm(3+) Ho(3+) doped LaOF tetragonal nanocrystals have been investigated. Bright fluorescence emissions are obtained co-doped Tm(3+)/Ho(3+):LaOF through UV infrared excitation. Green florescence from ions, which can be clearly seen with bared eyes, is when ion excited. Specific mechanism of the cross relaxation between ions explored spectroscopic measurements time domains. About 90% energy transfer efficiency weak radiative nonradiative...
A novel graphene oxide-polyvinyl alcohol/poly (N-isopropylacrylamide) hydrogel (GO-PVA/PNIPA hydrogel) with temperature sensitivity is prepared through in situ free-radical polymerization and freezing–thawing cyclic process. In this study, mechanical property sensitive of GO-PVA/PNIPA are investigated. The results show that the strength hydrogels enhanced increasing content GO also keeps good sensitivity. Graphene oxide acting as a multi-functional crosslinker between PVA PNIPA responsible...
