Novel self-healing epoxy coating
Researchers have recently presented a aemi-intrinsic self-healing epoxy coating using ionic liquid and super absorbent polymer.
In recent years, there has been a growing interest in self-healing materials due to their capacity to mend micro to nano-scale damages, enhancing longevity and reducing maintenance costs associated with equipment repair. a new study introduces a self-healing epoxy-based polymeric coating achieved through the incorporation of a reversible ionic liquid (IL) network and a superabsorbent polymer (SAP) in a straightforward one-pot blending process. The reversible interaction between the hydroxyl groups of epoxy and ionic groups initiates the healing process under dry conditions.
Significant potential
The modified sample with 8 % weight of IL exhibited a 63 % higher elongation break compared to pure epoxy. It is believed that this straightforward one-pot composition holds significant potential for various applications, including the construction and automotive industries.
The study has been published in Progress in Organic Coatings, Volume 199, February 2025.
