“…108 As an alternative, alkynyl groups can be introduced into the polymer matrix and then reacted with organic azides to ensure safety. [109][110][111] Second, the commonly used polymer skeleton for AEMs prepared by click chemistry are poly (aryl ether)s, however, the C O bonds of aryl ether containing polymers are likely to be degraded under alkaline conditions. 65,112,113 Other ether-free polymers such as PS, are usually mixed with flexible polymers for AEM due to their strong rigidity and poor film-forming properties.…”

Click chemistry has attracted tremendous attention in polymer synthesis due to its high efficiency, considerable yield, and simple synthesis/work-up procedures. Among the various functional polymer materials prepared by click chemistry, anion exchange membrane (AEM) is a kind of polyelectrolyte which contains cations attached to the polymer skeleton. Click chemistry not only provides facile pathways for the preparation of AEMs but also generates diverse architectures of AEMs with robust performance. The commonly used click chemistry in AEMs consists of: (i) Diels-Alder reaction, (ii) thiol-ene, and (iii) Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC). This review will focus on the advance of click chemistry in the preparation of AEMs, especially synthetic approaches for different AEMs and their corresponding application in energy-related fields, such as fuel cells, redox flow battery, electrodialysis, and so on.

“…Thiol groups are known to be highly reactive functional groups that participate in a variety of efficient chemical reactions such as nucleophilic addition and substitution reactions. In recent years, the radical thiol–ene and nucleophilic Michael type conjugate addition have also emerged as a powerful “click” reaction in polymer modification. − Due to the high efficiency of “click” reaction based transformations under mild conditions, these transformations have been extensively employed for modification of polymers and polymeric materials. − Exploitation of such thiol-based chemistries has been recognized as a powerful tool to stabilize electrospun nanofibers. Thiol-containing functional groups can be installed on polymeric backbone, or thiol-containing cross-linkers can be used to react with complementary reactive units on the polymer.…”

Polymeric nanofibers are finding a growing number of applications in various areas of biomedical sciences such as diagnostics, therapeutic delivery, and tissue engineering. Since such applications entail interfacing these materials with the biological milieu, it is often necessary that these nanofibers are hydrophilic in nature, yet stable in an aqueous environment. To date, several approaches to impart stabilization to polymeric nanofibers obtained using electrospinning have been developed. Various strategies utilizing chemical cross-linking of polymers have been exploited to impart stabilization of functional nanofibers fabricated using polymers that are soluble in the aqueous environment. This review highlights the various approaches developed to date for providing stabilization to hydrophilic polymeric nanofibers, along with showcasing the utilization of hydrophilic polymeric nanofibers in several biomedical applications.

Plastic is one of the most demanded materials on the planet, and the increasing consumption of which contributes to the accumulation of significant amounts of waste based on it. For this reason, a new approach to the development of these materials has been formed: the production of polymers with constant operational characteristics during the period of consumption and capable of then being destroyed under the influence of environmental factors and being involved in the metabolic processes of natural biosystems. The paper outlines the prerequisites for the development of the field of creating biodegradable composite materials, as well as the main technical solutions for obtaining such polymeric materials. The main current solutions for reducing and regulating the degradation time of polymer materials are presented. The most promising ways of further development of the field of bioplastics production are described. Common types of polymers based on renewable raw materials, composites with their use, and modified materials from natural and synthetic polymers are considered.
