Of or relating to the mesomorphic phase of a liquid crystal in which molecules are closely aligned in a distinct series of layers, with the axes of the molecules lying perpendicular to the plane of the layers.

[From Greek smēktos, smeared, from smēkhein, to wash off.]


(Chemistry) chem (of a substance) existing in or having a mesomorphic state in which the molecules are oriented in layers. Compare nematic See also liquid crystal
[C17: via Latin from Greek smēktikos, from smēkhein to wash; from the soaplike consistency of a smectic substance]


(ˈsmɛk tɪk)

(of liquid crystals) noting a mesomorphic state in which the arrangement of the molecules is in layers. Compare nematic.
[1920–25; < French smectique (1922) < Latin smēcticus cleansing]

Isotactic polypropylene (iPP) exhibits an interesting polymorphic behavior [1-5], sharing four crystalline structures: monoclinic [alpha]-form [6, 7], trigonal [beta]-form [1, 8-12], triclinic [gamma]-form [13, 14] and smectic phase [15, 16], Among these crystalline forms, [beta]-form is a metastable phase and can only be obtained under the following processing conditions: melt crystallization in the presence of specific heterogeneous nucleating agent (NA) [17, 18], by directional crystallization in certain temperature [19], or from melts subjected to shear [20, 21].
