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.

Introducing renewable compounds and dynamic covalent bonds into polymeric networks to achieve sustainability, self-healing, reprocessability is of great significance in reducing the carbon footprint materials. This study developed sustainable biomass adaptable (BCANs) using magnolol phenylborate. First, a prepolymer was obtained by phenolic hydroxyl group on diglycidyl ether for epoxy ring opening addition polymerization. Then, allyl used perform thiol–ene photochemical reaction with dithiol containing boronic ester; ultimately, magnolol-based BCANs were prepared. The dynamically reversible boron ester enable both recyclability self-healing properties, enhancing their application scope different scenarios. Additionally, confirms that after undergoing four man-made damages, BCANs' capability remained almost unchanged, even Young's modulus showed improvement. These demonstrate significant potential sustainability featuring monomer renewability, recyclability, characteristics are critically valuable replacing petroleum-based thermosets.
