New Liquid Crystalline Elastomeric Films Containing a Smectic Crosslinker: Chemical and Physical Properties
نویسندگان
چکیده
Side-chain liquid crystal elastomers (SC-LCEs) have been designed by using a new smectic crosslinker. Two types of monodomain films were prepared based on polysiloxane chains, with different relative concentration both crosslinker and mesogenic comonomers. The mesomorphic behavior the two SC-LCE systems was investigated differential scanning calorimetry polarized optical microscopy showing behavior: in one case, we obtained nematic film, other Smectic A film. In systems, mesophases stable wide temperature range. Moreover, possess relatively high orientation at room temperature. physical-chemical properties, such as local orientational ordering, structural organization, dynamics SC-LCEs’ constituents studied means static dynamic 2H NMR experiments, small-angle X-ray, wide-angle X-ray diffractions. relevant physical thermo-elastic thermo-mechanic behaviors, are reported discussed view practical applications.

Physical Aspects of Electro-optic Properties of Smectic Liquid Crystals
We present an E ective Internal Field Model for the antiferroelectric (AF) to eld induced ferroelectric (FF) transition of smectic CA. This model attributes the fast dynamics and high threshold elds of this transition to the large magnitudes of its in-plane polarization. We conclude that propagating ngers observed in the vicinity of the AF $ FF threshold eld can only be observed in holding elds...
متن کاملMicrodeformation of a polydomain, smectic liquid crystalline thermoset
The microdeformation and fracture mechanisms of a densely crosslinked, polydomain, smectic liquid crystalline thermoset (LCT) were investigated in order to gain some insight into its interesting mechanical properties (e.g. improved fracture toughness). A difunctional LC epoxy monomer, diglycidyl ether of 4,4′-dihydroxy-α-methylstilbene (DGDHMS), was crosslinked with the tetrafunctional, aromati...
متن کاملDeformation of a Polydomain, Smectic Liquid Crystalline Elastomer
A main-chain, polydomain, smectic liquid crystalline elastomer (LCE) was prepared by reacting the LC epoxy monomer, diglycidyl ether of 4,4′-dihydroxy-R-methylstilbene, with the aliphatic diacid, sebacic acid. When deformed in uniaxial tension, a “polydomain-to-monodomain” transition took place leading to bulk, macroscopic orientation. With this process was associated a plateau in the nominal s...
متن کاملInvestigating the mechanical, physical and antimicrobial properties of gelatin films containing Cinnamomum verum hydrosol
Hydrosol is a side product of essential oil extraction from plants. In this study, the effect of various ratios (5-100 %v/v) of cinnamon hydrosol replacement in the formulation of edible gelatin films was investigated. Physical properties were evaluated and the antibacterial properties of gelatin films against Staphylococcus aureus, Staphylococcus saprophyticus and Staphyl...
