Highly lubricative, self-healing, chemically degradable, anti-flaming and anti-irradiating magnetic gels simply prepared from binary mixtures of Fe3O4 nanoparticles and water

Magnetic gels are usually organic polymer–inorganic particle hybrids. We show that magnetic gels with high lubricity, self-healing, chemical degradability, and flame and irradiation resistances can be prepared solely with Fe 3 O 4 particles and water.
