Global Top 3 Companies Accounted for 77% of total Dielectric Elastomers market (QYResearch, 2021)
Across the world, the major players cover 3M, Dow, Altropol, etc.
Dielectric elastomers are made of a highly stretchable elastomeric film (mostly Silicone Rubber Elastomer, Acrylate Elastomer or Polyurethane Elastomer) as a dielectric, which is coated on both sides with highly flexible electrodes of graphite or carbon black.
Dielectric elastomers (DEs) are smart material systems that produce large strains. They belong to the group of electroactive polymers (EAP). DE actuators (DEA) transform electric energy into mechanical work. They are lightweight and have a high elastic energy density. They have been investigated since the late 1990s. Many prototype applications exist.
The dielectric elastomer consists of a polymer flexible film sandwiched between upper and lower layers of flexible electrodes, developed and developed by SRI International, a non-profit international research organization, in the second half of 1991. In the external electrical stimulation, the dielectric elastomer can change the shape or volume; when the external electrical stimulation is removed, the dielectric elastomer can restore to the original shape or volume, resulting in stress and strain to convert electrical energy into mechanical energy.
Dielectric elastomers are characterized by large electrical deformation, high energy density, fast response, low viscoelastic hysteresis (mechanical) loss, and high conversion efficiency. They are mainly used for the production of lightweight, miniaturized and high-precision actuators. Potential of an intelligent material. Dielectric elastomer actuator principle was first proposed by Wilhelm Conrad Rntgn in 1880, the voltage applied to the electrode 2, the resulting two-electrode charge between the opposite sex electrostatic attraction in the direction of film thickness of the elastic film; In the horizontal direction, the electrostatic repulsion of the same-sex charge expands the film on the single-sided electrode, resulting in variations in thickness and area: the thickness decreases and the area expands.
Dielectric elastomers and inherently conductive polymers (ICP), inherently dissipative polymers, conductive plastics and ferroelectrets adds up to total electroactive polymers market. The electroactive polymers (EAP) are part of the broad group of smart materials. The use of polymers with electroactive response has only emerged in the last decade with the introduction of new materials which have significant displacement levels. These materials are highly attractive for their low-density, large strain capability, superior spectral response and resilience. In general, the biggest advantages over conventionally used systems in most application fields are the intermittent displacement they can provide, an adaptable stiffness combined with variable size and form factors from micrometres to metres.
According to the new market research report “Global Dielectric Elastomers Market Report 2023-2029”, published by QYResearch, the global Dielectric Elastomers market size is projected to reach USD 0.05 billion by 2029, at a CAGR of 9.8% during the forecast period.
