Abstract

In this study, new hyper-crosslinked polymers (HCPs) were synthesized by crosslinking polyaramids via the Friedel-Crafts (FC) method for the first time. Polyaramids were synthesized using p-phenylenediamine (PDA), 4-aminophenyl ether (APE), and 4-aminophenyl sulfone (APS) and crosslinked with 1,4-bis(chloromethyl)benzene (BCMB) to form HCPs. The synthesized HCPs were characterized using FT-IR, BET, SEM, and TGA. The surface areas of HCPs ranged from 442 to 582 m² g^-1, with pore volumes between 0.50 and 0.61 cm³ g^-1. CO₂ adsorption experiments demonstrated that HCPs exhibited significant adsorption capacities, with values of 2.25, 2.56, and 2.29 mmol g^-1 for HCP-TPC1, HCP-TPC2, and HCP-TPC3, respectively. Despite their moderate surface areas, these values indicated that functional groups within the polymer structures, including amides, amide-ethers, and amide-sulfones, played a critical role in CO₂ adsorption. This study presents a novel approach to synthesizing HCPs from polyaramids using the FC method, contributing to developing new efficient CO₂ adsorbents.
