Flame-Retardant Ionic Conductive Elastomers with Multiple Hydrogen Bonds: Synthesis, Characterization, and Strain Sensing Applications

Molecules, Год журнала: 2025, Номер 30(8), С. 1810 - 1810

Опубликована: Апрель 17, 2025

Flammability is a significant challenge in polymer-based strain sensing applications. In addition, the existing intrinsic flame retardant not elastic at room temperature, which may potentially damage flexible equipment. This study presents series of flame-retardant ionic conductive elastomers (ICEs) (denoted as PCAIPx) containing phosphorus from phytic acid (PA) and nitrogen choline chloride (ChCl) with multiple hydrogen bonds synthesized using simple efficient one-pot UV-initiated radical copolymerization polymerizable deep eutectic solvent (PDES). The limiting oxygen index (LOI) value increased 24.1% for pure PCAI without PA to 38.3% PCAIP7.5. SEM analysis residual char shows that formation dense continuous layer effectively worked shield, preventing further decomposition undecomposed polymer inside while hindering transmission heat mass isolating required combustion. bonds’ cross-linked structure phosphorus-containing elastomer demonstrate superior elasticity (elongation break up 2109%), durability, tear resistance excellent adhesive properties. Application PCAIPX sensors showed has cyclic stability exhibited repeatable stable change signals response repetitive bending motions wrist, fingers, elbow, knee. Consequently, this provides strategy development ICE can reduce fire hazards be applied other fire-risk fields such personal protection, firefighting, sports

Preparation and properties of alginate based flame-retardant epoxy resin materials

Journal of Fire Sciences, Год журнала: 2025, Номер unknown

Опубликована: Апрель 30, 2025

Copper alginate (CA) and manganese (MA) were prepared from the polysaccharide biomass sodium alginate, these two alginates introduced to epoxy resin (EP) improve flame retardancy. The limiting oxygen index (LOI), vertical combustion (UL-94), cone calorimetry (CCT), thermogravimetric analysis (TGA) have been employed analyze impacts of on retardancy, thermal stability, char formation characteristics EP. Compared pure EP, when 20 wt% CA or MA was added, LOI increased by 5.6% 6.7%, respectively, no melt drops appeared. Because having catalytic carbonization effects, residual EP composites containing significantly, 5.53% 9.56%, respectively. peak heat release rate (PHRR) total (THR) composite drastically reduced. PHRR is reduced 38.9% 33%, while THR decreased 27% 31%, In addition, smoke production approximately 17% 30%, scanning electron microscope (SEM) tests revealed that had a stronger charcoal-forming ability, their charcoal layers more homogeneous compact microstructures. Briefly, CA, can effectively promote matrix in condensed phase, flame-retardant properties are improved.
