Journal ArticleDOI
Conformation and packing of various crystalline cellulose fibers
TL;DR: An overview of conformation and packing arrangements of crystalline cellulose allomorphs (cellulose Iβ, II, III 1, IV 1, IV 2, complexes with ethylenediamine, water, Na) is provided and basic data are presented in figures and in tables as discussed by the authors.
Journal ArticleDOI
4. Characteristics of cellulose acetates 4.1 Characterization and physical properties of cellulose acetates
TL;DR: In this article, an overview of the basic features of cellulose acetate of various degree of substitution in the solid and liquid crystalline state as well as in solution is provided. But the authors do not discuss the properties of mixed esters.
Journal ArticleDOI
Structural Models for Some Liquid Crystalline Cellulose Derivatives
Ulrike Vogt,Peter Zugenmaier +1 more
TL;DR: In this paper, models for helicoidal cholesteric structures are proposed for some cellulose derivative/solvent systems and the pitch of these structures is determined by independent methods as a function of temperature, concentration, solvent, degree of polymerization.
Journal ArticleDOI
Smectic-A*-smectic-C* transition in a ferroelectric liquid crystal without smectic layer shrinkage.
Frank Giesselmann,Peter Zugenmaier,Ingo Dierking,S. T. Lagerwall,Bengt Stebler,Miroslav Kašpar,Vĕra Hamplová,Milada Glogarová +7 more
TL;DR: The smectic layer spacing of a nonfluorinated ferroelectric liquid crystal (FLC) compound with almost no shrinkage and only minor tendency to form zigzag defects was characterized by small angle x-ray diffraction, suggesting a pure second-order phase transition far from tricriticality.
Journal ArticleDOI
Coupling of liquid crystalline and polymer network properties in LC-elastomers
TL;DR: In this paper, the authors studied the electrical properties of a slightly crosslinked ferroelectric liquid crystalline elastomers in the vicinity of the smectic C-smectic A phase transition and showed that the internal mechanical stress induced by the network formation appears to act like an external electric bias voltage.
