Purpose: The purposes of this study explore the possibility of total control the agglomeration of nanoborates powders. The great potential of PDLCs can be enhanced by using dye-doped or nanoparticles-doped materials, such as borates [1]. It is important to know how to prepare nanoparticles in order to obtain a high level of dispersion in the composites. Otherwise, even small an agglomeration does not give a possibility on the appropriate characteristic of properties and interpretation of the results. The deagglomeration methods applied until now give the decrease of agglomeration to a lesser extent than our method. Characteristic size and shape of particles made with sol-gel process is difficult to perform. Design/methodology/approach: Nanopowders samples of YAB and LCBO were prepared with sol-gel method. Deagglomeration process was carried out using acetic acid. The morphology and size of nanopowders were investigated by scanning electron microscopy (SEM). The crystallite sizes were determinated with IPS UA method. Findings: It was confirmed that the acetic acid influence on the decrease of agglomeration. It was also determined of conditions for preparation borates nanopowders samples (concentration acetic acind time and temperature of drying prepared samples). We have proved that a reagent used for deagglomeration process does not affect the structure of the investigated nanoborates used in an experimental. Research limitations/implications: The results can be used to the prepared of nanocompades of borates to observe a morphology and reliable assessment of nanocrystalline size. Originality/value: Our study shows how to prepare a sample of particles to observe morphology and measure the size of nanograins. In our study we found excellent solution, the medium, which not influence the inorganic nanomaterial structure. Result seems to be excellent and very perspective. We have showed as that measurement type influence the results of particles size.
