Lauric　acid　(LA)/SiO2　shape-stabilized　phase　change　materials　(PCMs)　were　fabricated　by　a　facile　one-pot　method　involving　co-hydrolysis　and　co-condensation　process　of　tetraethylorthosilicate　(TEOS)　and　methyltriethoxysilane　(MTES).　With　increasing　the　volume　ratio　of　MTES　to　TEOS,　the　surface　of　LA/SiO2　PCMs　changed　from　hydrophilic　to　highly　hydrophobic,　and　the　melting　latent　heats　decreased　from　93.8　J/g　to　60.3　J/g.　These　composite　PCMs　exhibited　high　thermal　stability　and　effective　storage　of　the　latent　heat,　demonstrating　suitable　for　applications　in　regulation　and　maintenance　of　temperature.
