“…34 Additionally, Ziemann et al effectively developed cross-linked PES membranes directly, which exhibited stability in N,Ndimethylformamide and trichloromethane (CHCl 3 ), achieved through the diazotization/dediazonization of a multidentate aromatic amine for cross-linking. 35 The aforementioned cross-linked membranes demonstrate commendable solvent resistance, thermal stability, and superior mechanical properties. Nevertheless, the cross-linking methods employed need severe postprocessing conditions, including high temperatures, organic solvent systems, and strong acids/bases.…”

An extensive amount of research has been devoted to the design and fabrication of solvent-resistant nanofiltration (SRNF) membranes. In the present research, a semi-interpenetrating polymer network (semi-IPN) system, which is based on poly(ether sulfone) (PES) and nitrogen-rich compounds, was utilized to fabricate SRNF membranes via click reactions. Specifically, the polymer N-rich-p (alkyne) and cyanuric triazide (CC-N 3 ) were synthesized from cyanuric chloride and subsequently integrated as cross-linking agents into the PES membrane matrix. The morphology and structure of the fabricated membranes were comprehensively examined with multiple methods such as attenuated-total-reflectance Fourier transform infrared, NMR, X-ray photoelectron spectroscopy, atomic force microscopy, and field-emission scanning electron microscopy. Thermal properties examined through thermogravimetric analysis and mechanical attributes including tensile strength showed a notable enhancement compared to the original membrane. The fabricated membranes demonstrated superior stability in solvents like methanol (MeOH), ethanol (EtOH), trichloromethane (CHCl 3 ), tetrahydrofuran (THF), and N,N-dimethylformamide (DMF). Performance evaluations, encompassing solvent permeance, contact angle, porosity assessment, and dye rejection tests, indicated that an increase in cross-linking agents led to improved resistance against organic solvents. Furthermore, the performances of the prepared cross-linked membranes in rejecting dyes Reactive Red, Methylene Blue,

“…Due to the amorphous nature of polyarylsulfone (PAS), both the particles and thin film products of PAS exhibit high transparency. This characteristic fulfills the fundamental criteria for the preparation and development of optical thin films [ 103 , 104 ]. In addition, similar to PAK materials, PAS does not contain amide or imide structures in its structure, so PAS offers significant benefits in terms of acid and alkali corrosion resistance and weather resistance [ 99 ].…”

SPECPs are electrochromic polymers that contain special engineering plastic structural characteristic groups (SPECPs). Due to their high thermal stability, mechanical properties, and weather resistance, they are also known as high-performance electrochromic polymer (HPEP or HPP). Meanwhile, due to the structural characteristics of their long polymer chains, these materials have natural advantages in the application of flexible electrochromic devices. According to the structure of special engineering plastic groups, SPECPs are divided into five categories: polyamide, polyimide, polyamide imide, polyarylsulfone, and polyarylketone. This article mainly introduces the latest research on SPECPs. The structural design, electrochromic properties, and applications of these materials are also introduced in this article, and the challenges and future development trends of SPECPs are prospected.
