This disclosure provides a method for preparing a current collector. The method includes: (1) anchoring vinyl groups onto the surface of textiles through the silanization between hydroxyl groups and coupling agents; (2) synthesizing polyelectrolyte brushes through in-situ radical polymerization; and (3) obtaining catalyst ions on the polyelectrolyte brushes through ion-exchange and obtaining metal-coated layers through subsequent electroless deposition). The current collector according to the present disclosure has high electrical conductivity and excellent mechanical flexibility, and thus the lithium ion battery including the same is suitable for portable and wearable electronic devices.

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 are an aniline anhydride, a preparation method therefor, and a polyaminoacid graft chain. In the presence of an acid binding agent, an addition-elimination reaction is carried out between N-phenyl amino acid and Boc anhydride to obtain N-phenyl-Boc-glycine; and under a nitrogen atmosphere, the N-phenyl-Boc-glycine is subject to cyclization to obtain the aniline anhydride. The polyaminoacid graft chain can be obtained using the aniline anhydride disclosed by means of chemical grafting and thus be covalently bonded with fiber. The fastness is high, the wearability of fabric is not affected, and the problem of low fastness of water-repellent fabric obtained by coating is solved. The polyaminoacid graft chain is biocompatible, naturally degradable and environmentally friendly, and is consistent with the current trend of developing green chemicals.
