Аннотация:Atomicforce microscopy (AFM) has been applied in a fluid environment to determine the size
distribution function of nanoparticle aggregates in an aqueous magnetic fluid with magnetite particles coated by polyacrylic acid for stabilization. It is proposed to use an external magnetic field to anchor aggregates on the substrate. The data are compared with the AFM data for dried precipitates of the system under consider ation, formed during evaporation of the liquid carrier under different conditions, as well as with the particle size distribution in the initial system obtained from smallangle Xray scattering data.
