Several poly(ethylene-co-methacrylic acid) copolymers have shown the unique ability to self-heal following projectile puncture, with the punctured site subsequently holding pressures in excess of 3 MPa. Four specific materials (ionomers and non-ionomer copolymers) were examined to determine if ionic interactions are responsible for puncture reversal. A range of novel experiments including peel, projectile, and quantitative post-puncture testing were used to determine that ionic content is not… 
SELF-HEALING OF POLY(ETHYLENE-CO- METHACRYLIC ACID) COPOLYMERS FOLLOWING BALLISTIC PUNCTURE
Poly(ethylene-co-methacrylic acid) (EMAA) copolymers and ionomers have been observed to self-heal following ballistic puncture. Contrary to the repair mechanism of other engineered systems, the
Thermal characteristics of the self-healing response in poly(ethylene-co-methacrylic acid) copolymers
TLDR
The results supported the defined healing model and provided additional information on the healing process in both its thermal dependence and general mechanism, and a new DSC method was developed for probing the thermal history of healed films which may lead to a more complete mechanistic model.
