In this work,we report a simple microfluidic strategy for controllable fabricating SiO2 microparticles containing inorganic phase change material of Na2SO4·10H2O for thermo-regulation.With incorporation of sodium borate and distribution of Na2SO4·10H2O inside SiO2 matrix,the microparticles effectively solve the common problems of phase separation and super-cooling for Na2SO4·10H2O.Monodisperse microfluidic water-in-oil(W/O)emulsions are used as templates for fabricating the microparticles via hydrolysis and condensation reaction of tetraethyl silicate and 3-aminopropyltriethoxysilane at droplet interfaces.
