Predictive Model for Epoxy‐Amine Polymerizations at Decreased Tc Using Variable Frequency Microwaves

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Two‐way interaction of basicity and entropy. ABSTRACT This study presents a predictive model for the thermo‐mechanical properties of epoxy polymers cured with Variable Frequency Microwave (VFM) processing. The model is based on properties derived from the structural features of the epoxide and amine precursors.

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.
