Polyurethane dielectric energy storage

Which plasticizers are used in thermoplastic polyurethane?

Thermoplastic polyurethane (PU) with high relative permittivity (∼8) was chosen as the elastic matrix. Barium titanate (BT) nanoparticles and dibutyl phthalate (DBP) plasticizers, which were selected to improve the permittivity and mechanical properties, respectively, were blended into the PU matrix.

Can polyurethane-based ternary composites harvest electric energy?

The lack of ideal dielectric elastomers, after nearly two decades of research, has become the bottleneck for DEGs’ practical applications. Here, we fabricated a series of polyurethane-based ternary composites and estimated their potential as DEGs to harvest electric energy for the first time.

Who are the authors of advanced dielectric elastomer based on acrylate and polyurethane?

Yu Zhao, Jun-Wei Zha, Li-Juan Yin, Sheng-Tao Li, Yong-Qiang Wen, Zhi-Min Dang. Constructing advanced dielectric elastomer based on copolymer of acrylate and polyurethane with large actuation strain at low electric field.

Why do we need dielectric capacitors for continuous miniaturization of electronic devices?

The continuous miniaturization of electronic devices and electric equipment requires high energy-storable dielectric capacitors. Therefore, seeking dielectric m

Can modified silica reduce the elastic modulus of polyurethane?

A novel and straightforward approach was employed to augment the dielectric constant and diminish the elastic modulus of polyurethane (PU) through the integration of modified silica (NSiO 2) into the matrix.

What is a rational balance between mechanical and dielectric properties?

In general, it is necessary to establish a rational balance between the mechanical and dielectric properties, which is of substantial importance in the practical application of the DE. Silica (SiO 2) is a highly versatile reinforcing filler that can greatly enhance the mechanical properties of elastomeric composites.
