• • SCSP-WA treatment yields a 6.04-fold increase in elongation at break, directly enhancing flexibility for bioelectronic substrates that must endure repeated mechanical deformation without fracture.
• • Leakage current is reduced by 98.5%, a critical improvement for electrical insulation in implantable or wearable devices where ionic leakage can cause signal noise or short circuits.
• • The process achieves simultaneous lightweighting and strengthening, with enhanced Young’s modulus and tensile strength, enabling thinner, more durable membranes for acoustic transducers and flexible sensors.
• • Supercritical CO2 is fully recyclable, reducing greenhouse gas emissions and aligning with carbon-neutral manufacturing mandates, offering a scalable, eco-friendly purification alternative to solvent-intensive processes.
