Analysis of the Degradation of Thermochromic Sensors in Electrical Devices

Journal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
This study examines the degradation of microencapsulated leuco thermochromic pigments, both pure and embedded in epoxy, under thermal, cyclic, and QUV aging. UV radiation is the main factor causing irreversible loss of thermochromism due to microcapsule damage and solvent loss, while thermal exposure produces minor effects.
