Journal ArticleDOI
Effect of multilactate chiral part of liquid crystalline molecule on mesomorphic behaviour
TL;DR: In this article, the relationship between the molecular chain structure and mesomorphic properties of lactic acid derivatives with particular molecular core forming the polar mesophases is discussed, and the presence of the keto group increases the temperature range and values of the spontaneous polarisation of polar liquid crystalline phases.
Journal ArticleDOI
Dielectric behaviour of the composite system: multiwall carbon nanotubes dispersed in ferroelectric liquid crystal
TL;DR: In this paper, Ferroelectric liquid crystal-multiwall carbon nanotube (FLC-MWCNTs) composite systems have been prepared by dispersing low (0.03 and 0.10) concentration of MWCNTs in the liquid crystal matrix.
Journal ArticleDOI
Design of advanced multicomponent ferroelectric liquid crystalline mixtures with submicrometre helical pitch
TL;DR: In this paper, new functional multicomponent ferroelectric liquid crystalline mixtures have been designed while searching smart self-assembling materials with submicrometre periodicity of the helical structure.
Journal ArticleDOI
An effect of structurally non-compatible additive on the properties of a long-pitch orthoconic antiferroelectric mixture
Wiktor Piecek,Alexej Bubnov,Paweł Perkowski,Przemysław Morawiak,K. Ogrodnik,W. Rejmer,M. Żurowska,Věra Hamplová,Miroslav Kašpar +8 more
TL;DR: In this article, the effect of additive of structurally non-compatible antiferroelectric dopant on the phase structure, transition temperatures, and electrooptical properties of an orthoconic mixture W1000 3 was investigated with thermal, electro-optical, and XRD methods.
Journal ArticleDOI
Photosensitive self-assembling materials as functional dopants for organic photovoltaic cells
Alexej Bubnov,Agnieszka Iwan,Martin Cigl,Bartosz Boharewicz,Igor Tazbir,Kamil Wójcik,Andrzej Sikora,Věra Hamplová +7 more
TL;DR: In this article, the effect of doping on the bulk-heterojunction solar cell properties and characteristics was investigated in terms of power conversion efficiency improvement considering specific chemical structure of the compounds used as functional dopants and the annealing temperature of an active layer.
