| Abstract: | The change in the domain texture of the 5CB nematic liquid crystal on the surface of a polyvinyl butyral gelatinous polymer
solution cured in a magnetic field is studied optically. The alignment of the nematic is described by the effective order
parameter S* of the polydomain cells. The anchoring energy of a liquid crystal with gelatinous polymer W
ϕ = 1 × 10−3 erg/cm2 is determined. |
