Les auteurs ont démontré l'alignement local de cristaux liquides nématiques avec une structure de micro-réseau locale fabriquée par le durcissement d'un matériau durcissable aux ultraviolets via une technique de micro-fabrication tridimensionnelle connue sous le nom d'écriture laser directe à excitation à deux photons [1]. L'alignement moléculaire des cristaux liquides nématiques sur les structures de micro-réseau fabriquées a d'abord été étudié par les observations d'une région nématique torsadée locale dans une cellule à cristaux liquides constituée d'un substrat avec une structure de micro-réseau fabriquée localement et d'un contre-substrat en polyimide frotté. . L'observation au microscope optique polarisant des structures de micro-réseau a indiqué que les molécules de cristaux liquides se sont alignées parallèlement aux rainures de la structure de micro-réseau et que l'alignement local a été réalisé avec succès. Les caractéristiques d'alignement des cristaux liquides sur ces micro-réseaux ont également été étudiées et discutées quantitativement en détail grâce à la mesure de l'énergie d'ancrage par la méthode conventionnelle d'équilibre de couple et la méthode Berreman. L'énergie d'ancrage azimutal du micro-réseau s'est avérée être de l'ordre de 10-6 J / m2 et inversement proportionnelle à la période du réseau.

Abstract: The authors have demonstrated the local alignment of nematic liquid crystal with local micro-grating structure fabricated by the curing of an ultraviolet curable material via a three dimensional micro-fabrication technique known as two photon excitation direct laser writing [1]. The molecular alignment of the nematic liquid crystals on the fabricated micro-grating structures was firstly investigated by the observations of a local twisted nematic region in a liquid crystal cell made of a substrate with locally fabricated micro-grating structure and a counter substrate with rubbed polyimide. The optical polarizing microscope observation of the micro-grating structures indicated that liquid crystals molecules have aligned parallel to the grooves of the micro-grating structure and that local alignment was successfully achieved. The alignment characteristics of the liquid crystals on these micro-gratings was also investigated and discussed quantitatively in details through the measurement of anchoring energy by the conventional torque balance method and the Berreman method. The azimuthal anchoring energy for the micro-grating was found to be in the order of 10-6 J/m2 and inversely proportional to the grating period.
