The methods and compounds disclosed herein relate to the surface modification of UHMWPs by means of a catalytic C—H bond insertion catalyst using a rhodium catalysts in conjunction with carbene-generating diazo compounds. The catalytic treatment imparts covalently added functionality to the UHMWPE surface. This functionality acts as an excellent grafting mechanism for grafting, bonding, or adhering further materials to the UHMWPs surface.

Disclosed are a water-repellent fabric and a preparation method therefor. A short carbon chain fluoroalkyl alcohol with different fluorine atom numbers used as a starter is firstly treated with an acylation reagent to generate a short carbon chain fluoroalkyl bromoacetate, and is then synthesized with N,N-bis(p-toluenesulfonyl) hydrazine to form a short carbon chain fluoroalkyl diazoacetate monomer, a fabric is respectively treated with an acylation reagent and N,N″-dimethylbenzenesulfonyl hydrazide in sequence to prepare a diazotized fabric having grafting sites on the surface thereof, and finally, a fluorine-containing polymer having a single carbon repeating unit is grafted to the surface of the fabric via a covalent bond by means of carbene polymerization, and thus a hydrophobic modified fabric is prepared. The entire reaction is carried out at a low temperature/room temperature, the operation is simple, and the process is environmentally friendly.

Disclosed is a carbon-based fiber sheet and a lithium-sulfur battery including the same. The carbon-based fiber sheet for the lithium-sulfur battery is doped with a high concentration of nitrogen and thus plays a role of preventing diffusion by adsorbing lithium polysulfide eluted from a positive electrode during charging and discharging, thereby suppressing a shuttle reaction and thus improving capacity and lifecycle properties of the lithium-sulfur battery.
