Stimulus-responsive polyurethane-urea polymer for protective coating

A recent article reported the synthesis of polyurethane-urea coatings using 1-(2-aminoe ethyl) - Methane-2-Ketone (UDETA) units, showing self-healing caused by temperature and humidity.
recent years, internal self-healing coatings have received more and more attention. The self-healing coating that maintains its original appearance and stimulates the response of polyurethane-pyride polymers after damage to the protective coating properties are attractive for a wide range of

new article reports on the synthesis of polyurethane-urea coatings with 1-(2-aminoe) -2-ketones (UDETA) units, showing self-healing caused by temperature and humidity. Volume heat and spectral analysis provides an in-depth understanding of the mechanism of self-healing, showing that absorbed water can interfere with the molecular and in-molecule hydrogen bonds of the polymer chain and reduce the glass transition temperature of the polymer. Temperature-mediated self-healing can be performed at temperatures of 80 to 200 degrees C.
polyurethane-pyride polymer has been shown to be beneficial for damping applications
in addition to self-healing, the molecular dynamics of polyurethane-pyride polymers have been shown to be beneficial for damping applications, as demonstrated by dynamic dynamics analysis. As a result, polymer systems have properties that can be used in two different applications, namely coatings and wetting materials with self-healing and corrosion protection properties.
