In this work, we used a stoichiometric mixture of bisphenol-A diglycidyl ether (BADGE) and amineterminated polyoxypropylene glycol (JeffAmine D-230) as a polyepoxy model confined between smooth alumina substrates as an inorganic substrate model, in combination with an SFA under different relative humidity environments. The SFA and alumina fabricated surfaces allowed us to conduct real-time surface imaging and refractive index changes of the confined polyepoxy using fringes of equal chromatic order (FECO) technique. Simultaneously, we monitored curing strains and stresses from prior to gel-point conversion to fully cured over 48 hrs.
