TiO₂ nanoparticle – liquid crystal interaction with smectogenic monomers and their electropolymerised polymers

Freedericksz Transitions in Twisted Ferronematics Subjected to Magnetic and Laser Field

“…To obtain the twisted configuration, the rubbing directions on the plates are perpendicular to each other, meaning that the molecules rotate around the Oz axes with an angle of ϕ that increases from 0 (on the bottom plate) to π/2 (on the top one). In the absence of any external field (magnetic or laser), the ferromagnetic nanoparticles gather in long chains parallel with the nematic molecules' long axes (Figure 1a), as shown in previous research [2,12]. When a magnetic field is applied to the Oz direction, it acts both on nematic and ferroparticles.…”

“…These technologies are consequences of years of research into nanoparticle properties. In LC research fields, many studies have been performed on magnetic nanoparticle dispersions in nematic phases, called ferronematics [1][2][3][4][5][6][7][8][9][10][11][12]. There is also interest in other particles and their effect on the molecular order of the host [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”

The Influence of Single-Walled Carbon Nanotubes on the Dynamic Properties of Nematic Liquid Crystals in Magnetic Field

“…After the discovery of nanomaterials and the synthesis of new nanoparticles, interest in the analysis of their physical properties increased in order to identify as many applications as possible [1][2][3][4][5][6][7][8][9][10]. Carbon-based nanoparticles, such as nanotubes, graphene, fullerene, or nanotori were analyzed both from experimental [11][12][13][14][15][16] and theoretical points of view [17][18][19][20][21][22].…”
