Transmission electron microscopy of composite materials based on hypercrosslinked polystyrenes with nanodispersed inorganic compounds
Nanocomposite materials with magnetic and catalytic properties based on hypercrosslinked polystyrenes (HLP) and inorganic compounds introduced into a polymer by means of chemical precipitation were investigated. Transmission electron microscopy (TEM) revealed that when ferric oxides are precipitated in hypercrosslinked gel-type polystyrene, nanodispersed particles 8 ± 2 nm in size are formed, and when the ferric oxides are precipitated in hypercrosslinked biporous polystyrene, larger nanoparticles (∼16 nm in size) are formed.
