High Flame Retardancy of Carbon Nanotubes Reinforced Polyelectrolyte Multilayered Nanocomposites

Journal of Applied Polymer Science, Год журнала: 2025, Номер unknown

Опубликована: Март 7, 2025

ABSTRACT In pursuit of multifunctional flame‐retardant coatings, a layer‐by‐layer (LbL) assembly was used to create hybrid nanocoatings by alternating the deposition positively charged chitosan (CH) and negatively sodium lignosulfonate (Lg). Carbon nanotubes (CNT), dispersed in an Lg solution, were incorporated as robust reinforcements polymer nanocomposites. Their high aspect ratio dense network within CH/CNT‐Lg layers resulted coatings that notably thicker heavier compared those constructed without CNT. horizontal flame tests, presence CNT led superior fire resistance. Cone calorimetry further demonstrated incorporating into single coating completely suppressed second peak heat release for polyurethane foam (PUF). Additionally, total smoke release, production, maximum average rate emission, effective combustion reduced 68.9%, 72.7%, 47.7%, 57.3%, respectively, uncoated PUF. These improvements retardancy are attributed enhanced thermal stability char yields provided Overall, given ease applying LbL assembly, this strategy offers promising halogen‐free approach improving safety both natural synthetic fibers.

Fibers, Год журнала: 2024, Номер 12(5), С. 44 - 44

Опубликована: Май 17, 2024

This study reports process optimization studies of silica and zinc oxide-based flame-retardant (FR) coatings on cotton fabric for protective clothing enhanced flammability properties. The experiments were designed by central composite design (CCD) using response surface methodology (RSM) to assess the synergistic effects oxide FR coating. These prepared sols coated fabrics a simple dip dry cure process. resulting FR-finished characterized SEM, mechanical properties, flame retardancy, air permeability. SEM results confirmed homogenous spreading particles fabrics. From TGA results, it was noticed that incorporation ZnO in nano-sols improved thermal stability sol–gel-treated showed excellent comfort which shows their suitability fire-retardant clothing. RSM analysis proved predicted values are good agreement with experimental since R2 time ignite, spread time, permeability greater than 0.90. optimized concentration found be 0.302% 0.353%, respectively, further confirmatory experiments. successfully coating nanoparticles properties
