Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Exploring Microencapsulated Magnesium Tetraborate: A Promising Flame‐Retardant Additive for Polyurethane‐Based Composites

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
Flame‐retardant polyurethane composites were synthesized by in situ polymerization. Fire performance and thermal decomposition of boron‐bearing compounds in PU were examined. ABSTRACT Boron compounds exhibit low toxicity and diverse molecular structures, rendering them effective flame‐retardant additives in polymer‐based materials through various ...

Occupational Allergic Contact Dermatitis From Over‐Ear Headphones: Chemical Analysis Reveals Octylisothiazolinone and Other Potential Skin Sensitizers

open access: yesContact Dermatitis, EarlyView.
ABSTRACT Background Over‐ear headphones are a growing source of allergic contact dermatitis (ACD). Identifying well‐known and new culprit sensitizers in such products is challenging because of a lack of labelling and limited cooperation from manufacturers.

Contact Allergy to Textile Dye Mix in Italy: A SIDAPA Multicentre Observational Study

open access: yesContact Dermatitis, EarlyView.
From January 2020 to March 2025, 7633 patients (69.2% females) underwent patch test with textile dye mix 6.6%. 281 (3.7%, F 77.2%) resulted positive (59.8% relevant), mainly non‐occupational (89.9%). The observed prevalence (3.7%), even if with decreasing trend, exceeds that of previous Italian (1.5%) and European (2%–3%) studies.

Surface engineering of recycled high‐density polyethylene‐based wood–polymer composites via carbon black‐containing surface film coating

open access: yesColoration Technology, EarlyView.
Abstract This study evaluates carbon black nanoparticle (CB NP)‐reinforced surface films for improving the durability, thermal stability, fire performance and mechanical retention of recycled high‐density polyethylene (HDPE)‐based wood‐plastic composites (WPCs) after 12 months of natural weathering.
