摘要: We describe a convenient, one-step sol−gel route to composite polymeric organic−inorganic particles. The synthesis is based on performing the polycondensation within surfactant-stabilized emulsion of solution polymer polystyrene various molecular weights in tetraethoxysilane, with or without toluene, all dispersed basic ethanolic medium. parameters that dictate formation bicontinuous particles were explored and characterized by several methods including TEM, surface area porosity measurements, high-resolution XPS, TGA, DSC, UV, FTIR spectroscopies. are obtained monomodal distributions diameters range 200−500 nm, depending preparation conditions. phase extractable, when this extraction carried out porous silica obtained. Likewise, partial leads core−shell architecture. also found be good carriers for entrapped dye molecules no leac...
