In response to the burgeoning interest in enhancing the properties of liquid crystal composites,
this research systematically explores the intricate interplay between MBBA nematic liquid crystals
and ferroelectric barium titanate nanoparticles. The focus is modulating dielectric properties under
temperature, frequency, and an applied electric feld. Nuanced insights into temperature-dependent
behavior, parallel and perpendicular component alterations, and a nonlinear correlation between
nanoparticle concentration and dielectric constant are revealed. The study delves into dielectric
anisotropy, indicating a reduction with increasing temperature. Structural analyses validate size
reduction and crystal phase maintenance of barium titanate nanoparticles (NPs), emphasizing their
impact on dielectric characteristics. Frequency-dependent investigations underscore a consistent
decline in permittivity with rising frequency across nanoparticle concentrations. Application of an
electric feld in flling process of liquid crystal cells reveals irregular changes in dielectric constant,
holding promise for tailored applications in display technologies. These comprehensive fndings ofer
valuable insights into manipulating dielectric anisotropy properties of MBBA liquid crystal by a simple
method for potential advancements in optoelectronic devices and display technologies.
