摘要: Thermoregulated rigid polyurethane foams containing silica shelled nanoencapsulated phase change materials (NanoPCMs) were fabricated. Chemical composition and morphology of the composite characterized by Fourier transform infrared (FT-IR) spectroscopy scanning electron microscopy (SEM), respectively. Thermal properties evaluated differential calorimetry (DSC), thermogravimetric analysis (TGA), dynamic mechanical thermal (DMTA) methods. The NanoPCMs are homogeneously dispersed in a matrix. Higher contents lead to slightly increased cell size, minor decrease glass transition temperature (Tg), higher enthalpies. exhibit good reliability, reasonable thermoregulation property, fairly high compressive properties. In addition, property-density relationship for agrees well with Gibson–Ashby’s power law.
