A TPC-OTBS n-hexane solution is added to a mixture of TPC-OSOF, DMF, and DBU and allowed to stand to produce a crosslinked solvent gel; the crosslinked solvent gel is added to methanol, stirred, and dried to produce the porous crosslinked material. The gel acquired can be prepared into a pore-rich solid porous organic polymer material by means of solvent exchange. SEM and TEM are used to characterize the surface and internal morphologies of the solid material, and the porous morphology thereof is discovered, with large pores being the majority. Infrared and nuclear magnetic resonance are used to characterize the structure of a crosslinked polysulfate; the complete reaction of a sulfuryl fluoride group is proven by means of solid-state fluorine nuclear magnetic resonance spectroscopy and XPS element analysis; and the porous structure of the crosslinked polysulfate allows same to be provided with improved application prospect in terms of adsorption.

Porous crosslinked material, preparation and application thereof

A perfluoro compound includes perfluorobutyl ethylene (PFBE) and a fluoroalkane. The perfluoro compound has an azeotropic point between 40 degrees Celsius and 60 degrees Celsius, inclusive.

Liquid cooling while preventing electronic damage

The present invention provides a magnetic FeOnanosphere with PNH surface modification and application thereof in water treatment. First, 2,2-bipyridyl-5,5'-dicarboxylic acid is reacted with thionyl chloride to obtain 2,2-bipyridyl-5,5&#x2032;-diacid chloride; then 2,2-bipyridyl-5,5&#x2032;-diacid chloride and 1,4,8,11-tetraazacyclotetradecane react in the presence of triethylamine to obtain a polynitrogen heterocyclic polymer; the polynitrogen heterocyclic polymer is added into an aqueous solution with iron salt to obtain a magnetic FeOnanosphere with PNH surface modification which has strong light absorption ability, which improves its ability to catalyze in degradation of tetracycline under visible light, so that the pollutants are removed from water.

Magnetic FeOnanospheres with PNH surface modification and application hereof in water treatment

The present invention provides an In&#x2014;NH/g-CNnanocomposites with visible-light photocatalytic activity and application thereof, which can effectively remove organic pollutants (such as tetracycline) in water. First, the graphite phase carbonitride carbon (g-CN) was obtained by thermal condensation, and g-CNnanosheet was prepared by thermal oxidative etching. Then, acicular MIL-68(In)&#x2014;NH(In&#x2014;NH) was grown in situ on the surface of g-CNnanosheet by solvothermal method. The In&#x2014;NH/g-CNnanocomposites with high visible-light photocatalytic activity were obtained. The CNNS firstly was prepared in the present invention, which is beneficial to the needle-like In&#x2014;NHgrowing on the surface of CNNS and having close interfacial contact with each other, forming a heterojunction, promoting the separation of photogenerated electrons and holes pairs, and enhancing visible-light photocatalytic degradation of organic pollutants. The nanocomposites show high structural stability and reusability, which has great potential in the field of water remediation.
