Dielectric elastomers (DEs) are kinds of advanced functional materials, attracting more attention due to that they can used to fabricate ingenious devices. In this work, a series of advanced DEs based on the copolymer of polyurethane (PU) and acrylate, were chemically prepared through the condensation polymerization between p (BA-HEA), the n-butyl acrylate (BA) and hydroxyethyl acrylate (HEA) copolymer...
Most dielectric elastomers (DEs) need high operating electric field (>100 kV/mm) and the essential pre-strains to achieve satisfied actuation, which limits their widespread application. In this work, we prepare a series of high performance DEs using the common acrylate monomers through a versatile method. By adjusting the component of polymers, the advanced DE possess a high actuation coefficient...
High-permittivity (high-k) materials play a key role in advanced electronics and electrical power systems. How to prepare the flexible material with high permittivity and low dielectric loss turns out to be a hard work due to the essential low permittivity of polymers. In this work, a kind of ductile polymer-based composites was fabricated by incorporating ionic liquids into polymer matrices. The...
In this paper, we report the preparation and dielectric properties of reduced graphene oxide/polypropylene (rGO/PP) composites with an ultralow percolation threshold as low as 0.033 vol%. This value is the lowest among those that have been reported in graphene-filled composites. The rGO/PP composites were prepared through a latex technique, which consists of an in-situ chemical reduction of graphene...
Semiconductive polymer shielding layers of power cable require stable volume resistivity to protect the insulation layer from stress enhancements when carbon black (CB)/polymer composite undergoes thermal cycles. For the CB-filled polymer composites, CB would often re-aggregate when temperature is close to the melting point of polymer matrix, so that the conductive network would be destroyed. Re-distribution...
