Abstract In this study we used an amphiphilic diblock copolymer, poly(ethylene- b -ethylene oxide) (PE- b -PEO), as an organic template for the synthesis of mesoporous silica through evaporation-induced self-assembly (EISA). Using transmission electron microscopy (TEM), small-angle X-ray scattering (SAXS), and nitrogen adsorption/desorption isotherms, we investigated the effects of the tetraethyl orthosilicate (TEOS) and hydrochloric acid (HCl) contents on the EISA process. At a constant HCl… CONTINUE READING
