In particular, the coloring and bleaching times of the TNO-P<sub>60</sub> film is 12.4 and 18.3 s, and retained 91.7 % of the initial transmittance modulation (70.3 %) after 2000 cycles. In addition, the surface capacitance of TNO film modified by PDA can be risen to 238 %.

High-energy absorption occurred at a place close to the substrate induced by the oxidation of Si and on the top of the multilayers, which resulted in multilayers detaching from the substrate and forming bubble-like morphology.

Initially, a structure with circular-shaped domains characterized by double twisting of the surface linear defect is formed. Under the influence of an electric field, the domains take the shape of polygons. This system has an asymmetric selective reflection of light: the reflection of right-circularly polarized light close to 100% is observed at a normal incidence of radiation on the sample from the planar boundary conditions, while a selective reflection of light does not occur for radiation incident from the conical anchoring. The light transmission of the sample in the forward direction does not depend on which substrate the radiation falls on. This spectral behaviour is due to the peculiarity of the formation of the domain structure in the cholesteric layer, in which the circular domains are initially located only near the substrate with a conical anchoring.
