Thermochemical Recycling and Degradation Strategies of Halogenated Polymers (F−, Cl−, Br−): A Holistic Review Coupled with Mechanistic Insights

The Chemical Record, EarlyView.
This review aims to comprehensively address recent degradation techniques (physical, chemical and biological) of halogenated waste polymers with a prime focus on thermal degradation techniques. Exploiting various metal oxides during co‐pyrolysis is deemed a viable solution for recycling halogenated polymeric waste.

Chemical profiling and characterisation of anthraquinone‐based polyphenols as biocolourants from Cortinarius semisanguineus

Coloration Technology, EarlyView.
Abstract Anthraquinone dyes are known for their significant colour (brightness of shade in the red, blue and green areas) and light fastness properties compared with other synthetic dyes (such as azo‐based dyes). However, challenging multi‐step synthesis of anthraquinones and limited access to fewer substituents result in insufficient reactivity ...

Investigation into the aqueous and supercritical carbon dioxide dyeing of polyester and cellulose acetate: The influence of temperature and carriers on fabric coloration and dye levelling

Coloration Technology, EarlyView.
Abstract This paper investigated the effect of temperature and time on the dyeing of polyester and cellulose diacetate and demonstrated the benefits of supercritical carbon dioxide (SC‐CO2) dyeing. It was evident that the SC‐CO2 medium enabled effective coloration of polyester at lower temperatures, ca.

Rapid and high exhausted coloration technology: Dyeing of bovine hides under vacuum

Coloration Technology, EarlyView.
Abstract In the current study, the aim was to improve the dyeing properties of wet‐blue and crust leathers under vacuum conditions, increasing the dyestuff exhaustion, and thus obtaining environmental and economic gains. In this context, dyeing was performed using conventional dyestuff and water ratios in a vacuum environment with 20 kPa pressure, and ...

Biodegradable Sodium Alginate Films Enriched With Oils—A Review

Packaging Technology and Science, Volume 38, Issue 7, Page 587-609, July 2025.
The incorporation of oils into sodium alginate matrices has proven effective in enhancing their functional properties. Rich in bioactive compounds, such as natural antioxidants and antimicrobials, oils contribute to increasing the films' resistance to oxidation and their effectiveness in food preservation.

Preparation of Carbon Fiber–Reinforced Polymer Using Oxidatively Degradable Matrix Polymer: Recovery and Reuse of Carbon Fiber Sheet

Journal of Applied Polymer Science, Volume 142, Issue 23, June 15, 2025.
Carbon fiber–reinforced polymer (CFRP) was prepared from carbon fiber (CF) sheet with a diacylhydrazine‐crosslinked matrix polymer. The CF sheet was recovered without damage when the CFRP plate was treated with sodium hypochlorite NaClO solution.
