P. Mach et al., SURFACE-TENSION OBTAINED FROM VARIOUS SMECTIC-A LIQUID-CRYSTAL FREESTANDING FILMS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 302, 1997, pp. 181-186
Employing a straightforward experimental technique, we have investigat
ed the surface tension of various liquid crystal compounds in the smec
tic-A and smectic-A(d) phases. The results clearly demonstrate the sig
nificant role of molecular packing in determining the surface tension.
