The main target of the present research work is fabrication of low-cost poly(styrene) based membrane towards water filtration purpose. A zwitter ion functionalized poly(styrene) based random co-polymer was synthesized by one pot method. Acid and amine functionalized styrene-based co-polymer was synthesized by a free radical solution polymerization method in the presence of dicumylperoxide as a lone chemical initiator by one pot method under N2 atmosphere with vigorous stirring. The zwitter ion functionalization of styrene monomer was carried out through Friedel-Crafts alkylation method. The synthesized random copolymer was characterized using FT-IR, 1 H-NMR spectra, DSC, TGA, SEM, EDX, GPC, XPS, WCA, POM and XRD techniques. The tensile strength of the copolymer was tested. The FT-IR spectrum showed a peak corresponding to C-N stretching and O-H stretching. The DSC showed the highest Tg of 96.9 o C for the styrene based random copolymer.

Reversible deactivation radical polymerization (RDRP) is a controllable technique for free radical polymerization to synthesize polymer brushes. Macroinitiators have the advantage of grafting polymer brushes with high density over small molecule initiators due to the multiple active units in one molecule. However, there are still some shortcomings in the control of catalytic activity and polymer structure due to the unique segmental motion of macromolecules. In this work, we prepared one‐dimensional styrene polymer brushes via the atom transfer radical polymerization (ATRP) method using chlorinated polybutadiene (Cl‐LBR) as a macroinitiator and cuprous chloride (CuCl) as a catalyst. The effect of polymerization conditions on catalytic activity and polymer structure was investigated in detail. The ligands for CuCl including 2,2‐bipyridine (bpy) and pentamethyl‐diethylenetriamine (PMDETA) were also examined. Additionally, l‐ascorbic acid was adopted as a reducing agent to generate activator regenerated electron transfer (ARGET) ATRP in Cl‐LBR initiated system. In comparison with ATRP, ARGET ATRP can reduce the dosage of CuCl by 20 times. This work prepared one‐dimensional polystyrene polymer brushes with high polymerization rate and controllable structure through macromolecular initiators. This method provides a promising pathway for the preparation of one‐dimensional polymers with functional designs and demonstrates broad developmental potential in antifouling.

Developing solid‐state electrolyte with sufficient ionic conduction and flexible‐intimate interface is vital to advance fast‐charging solid‐state lithium batteries. Solid polymer electrolyte yields the promise of interfacial compatibility, yet its critical bottleneck is how to simultaneously achieve high ionic conductivity and lithium‐ion transference number. Herein, single‐ion conducting network polymer electrolyte (SICNP) enabling fast charging is proposed to positively realize fast lithium‐ion locomotion with both high ionic conductivity of 1.1 × 10−3 S cm−1 and lithium‐ion transference number of 0.92 at room temperature. Experimental characterization and theoretical simulations demonstrate that the construction of polymer network structure for single‐ion conductor not only facilitates fast hopping of lithium ions for boosting ionic kinetics, but also enables a high dissociation level of the negative charge for lithium‐ion transference number close to unity. As a result, the solid‐state lithium batteries constructed by coupling SICNP with lithium anodes and various cathodes (e.g., LiFePO4, sulfur, and LiCoO2) display impressive high‐rate cycling performance (e.g., 95% capacity retention at 5 C for 1000 cycles in LiFePO4|SICNP|lithium cell) and fast‐charging capability (e.g., being charged within 6 min and discharged over than 180 min in LiCoO2|SICNP|lithium cell). Our study provides a prospective direction for solid‐state electrolyte that meets the lithium‐ion dynamics for practical fast‐charging solid‐state lithium batteries.
