Naphthalene is a fungicide that can also be phase-change agent owing to its high crystallization enthalpy at about 80 °C. The relatively rapid evaporation of naphthalene as and shape instability after melting are problems solved in this work by placement into cured epoxy matrix. work's research materials included diglycidyl ether bisphenol A an resin, 4,4'-diaminodiphenyl sulfone hardener, or fungicide. Their miscibility was investigated laser interferometry, the rheological properties their blends before during curing rotational rheometry, thermophysical features process resulting differential scanning calorimetry, blends' morphologies transmission optical electron microscopies. resin were miscible when heated above This fact allowed obtaining highly concentrated mixtures containing up 60% high-temperature homogeneous with sulfone. initial solubility only 19% uncured but increased strongly upon heating, reducing viscosity reaction mixture, delaying gelation, slowing cross-linking. At 20-40% mass fraction naphthalene, it almost entirely retained dissolved state cross-linking metastable solution, causing plasticization polymer lowering glass transition temperature. half within polymer, while other formed coarse particles capable thermal energy storage. In summary, material stored 42.6 J/g 62-90 °C had temperature 46.4 maximum
