  A novel nanoencapsulated phase change material (PCM) based on an n-eicosane core and an inorganic silica shell was synthesized through sol-gel route by using tetraethyl-orthosilicate (TEOS) and sodium silicate as an inorganic silica-precursor at different conditions for enhanced thermal stability and phase change properties. Fourier transform infrared spectra confirm the chemical composition of synthesized nanocapsules. Scanning electronic microscopic images show that the nanocapsules consist of spherical morphology. Furthermore, nanocapsules present different particle size range between 250-550 nm with respect to their pH values; the optimum pH for n-eicosane/TEOS nanocapsules is 2.20, and 2.94 for n-eicosane/sodium silicate, respectively. In addition to this, capsules synthesized by using TEOS show small particle size distributions as compared to the ones integrated by using sodium .. Read More»
