摘要： The present invention provides a class of magnetic hydrogels with tissue-mimetic mechanical properties and photothermal welding/healing capability. In these hydrogels, a hybrid network involving aramid nanofibers, functionalized Fe3O4 nanoparticles, and polyvinyl alcohol (PVA) is accomplished by a stepwise assembly of the functional components. The engineered interactions between nanoscale constituents enable facile materials processing and confer a combination of excellent mechanical properties, magnetism, water content and porosity.

摘要： A preparation method of a perfluoropolyether-based magnetic liquid includes dispersing magnetic nanoparticles coated with graphene oxide into a solution of N,N-dimethylformamide to obtain solution A; dispersing a surfactant into dichloromethane, and adding triethylamine as a cosolvent to obtain solution B; mixing the solution A and the solution B uniformly, heating them under reflux and stirring them for a modification reaction; and after the modification reaction is completed, washing and drying a reaction product to obtain the modified magnetic nanoparticles coated with the graphene oxide; dispersing the modified magnetic nanoparticles coated with the graphene oxide into a base carrier liquid to prepare the perfluoropolyether-based magnetic liquid. The surfactant is a perfluoroalkylamine. The base carrier liquid is a perfluoropolyether oil. The modification reaction is performed at a temperature of 50 to 120° C. for a time period of 20 to 50 hours.
