Summary: Phytic acid-assisted PANi/PVA hydrogel with self-reinforcing features is developed, showing enhanced mechanical performance. Phytic acid plays a crucial role in salinizing aniline and forming hydrogen bonds with PVA, resulting in conductive PANi and structure orientation. The hydrogel exhibits improved fracture strength, Young’s modulus, and toughness after repetitive stretching, attributed to the anisotropic structures fixed by hydrogen bonds. The PVA/PA/PANi hydrogel shows good mechanical durability and reusability, making it a reliable strain sensor.

Summary: The injection of CO2 into oil reservoirs for enhanced oil recovery is widely used, although reservoir fractures can cause gas channeling. This study developed a novel plugging gel with excellent mechanical properties, fatigue resistance, and self-healing abilities to shut off CO2 flow. The gel, made of grafted nanocellulose and polymer network crosslinked by Fe3+, exhibited a stress of 1.03 MPa, a strain of 1491%, and self-healed to 98% stress and 96% strain after rupture. The introduction of TOCNF/Fe3+ improved energy dissipation and self-healing through dynamic coordination bonds and hydrogen bonds. The gel showed great potential for plugging high-pressure CO2 flow, making it a promising method for CO2-EOR and carbon storage.
