Electroelastic materials, as for example, 3M VHB 4910, are attracting attention as actuators or generators in some developments and applications. This is due to their capacity of being deformed when submitted to an electric field. Some models of thei

Study of the dielectric relaxation of poly(phenylpropyl acrylate) and poly(phenylpropyl methacrylate): effect of slight differences in chemical structure

Autor: Ricardo Díaz Calleja, Maria J. Sanchis, M. Carsí, B. Redondo-Foj, P. Ortiz-Serna, Angel Leiva, Deodato Radić, Ligia Gargallo

Publikováno v: Polymer International. 64:1733-1740

A comparative study of the dielectric relaxational behaviour of two structurally close polymers, containing aromatic side groups, was carried out in order to analyse how slight differences in the chemical structure affect the molecular responses to p

On the Non Linear Behaviour of Nematic Liquid Single Crystal Elastomers (NLSCE) Under Biaxial Mechanic and Electrical Force Fields

Autor: A. Quijano-López, P. Diaz-Boïls, Ricardo Díaz-Calleja, Pedro Llovera-Segovia

Publikováno v: Molecular Crystals and Liquid Crystals. 611:71-80

A continuum theory has been developed to give account of the three characteristic zones appearing in the “semisoft” behaviour of nematic single crystal elastomers under the effect of biaxial mechanic and electrical force fields considering higher

Electromechanical behaviour of biaxially stretched nematic liquid single crystal elastomers

Autor: Ricardo Díaz-Calleja, Pau Díaz-Boïls

Publikováno v: International Journal of Non-Linear Mechanics. 64:26-32

A slab of nematic-side-chain-liquid-single-crystal elastomer (NSCLSCE), with the director initially oriented in the z direction, is subjected to a pair of equal mechanical stretches and electrical force fields in x and y directions. These electric fi

Publikováno v: Chemical Physics Letters. 552:114-121

Dielectric behavior of two epoxy-based oligomers with covalently attached 4-amino-4′-nitroazobenzene NLO chromophore fragments is studied. Four processes of relaxation of dipole polarization, γ -, β -, β 1 -, and α -processes are identified by
