Elastomeric composites for flexible microwave substrates

Elastomeric composites with tuned electromagnetic characteristics

This paper presents a novel elastomeric composite that exhibits a deformation-induced change in chirality. Previous efforts primarily dealt with a coil array in air without chiral tuning. Here, a composite is created that consists of an array of parallel, metallic helices of the same handedness embedded in a polymer matrix. The chiral response of the composite depends on pitch, coil diameter, w...

Elastomeric substrates with embedded stiff platforms for stretchable electronics

Microwave Heating of Ceramic Composites

The microwave heating of a ceramic composite is modelled and analysed. The composite consists of many small ceramic particles embedded in a ceramic cement. The composite is assumed to be well insulated, and each particle is assumed to be in imperfect thermal contact with the surrounding cement. Based on these two assumptions an asymptotic theory exploiting the small Biot number and small non-di...

Preparation and Characterization of Shape Memory Elastomeric Composites

Shape memory polymers (SMPs) are a class of smart poly-meric materials that have the ability to " memorize " a permanent shape, be manipulated to retain or " fix " a temporary shape, and later recover to its original (permanent) shape upon a stimulus such as heat, electricity, or irradiation. 1-3 A large number of SMPs have been developed and utilized for actua-tors, deployable medical devices,...

Elastomeric nanoparticle composites covalently bound to Al2O3/GaAs surfaces.

This article reports the modification of Al2O3/GaAs surfaces with multifunctional soft materials. Siloxane elastomers were covalently bound to dopamine-modified Al2O3/GaAs semiconductor surfaces using MPt (M = Fe, Ni) nanoparticles. The sizes of the monodisperse FePt and NiPt nanoparticles were less than 5 nm. The surfaces of the nanoparticles as well as the Al2O3/GaAs substrates were modified ...
