High Electric Energy Density Polymeric Compositions, Methods Of The Manufacture Therefor, And Articles Comprising The Same

View page
US Patent:
20100067172, Mar 18, 2010
Filed:
Mar 13, 2009
Appl. No.:
12/403596
Inventors:
Shihai Zhang - State College PA, US
Qiming Zhang - State College PA, US
International Classification:
H01G 4/08
US Classification:
361323
Abstract:
Examples of the present invention relate generally to high electric energy density polymer film capacitors with high charge-discharge efficiency and fast discharge speed. For example, a high energy density polymer capacitor may be fabricated using a polymer blend comprising one or more high dielectric constant PVDF-based polymers (including homopolymers, copolymers and/or terpolymers) and one or more other polymer with low dielectric loss and high volume resistivity compared to the one or more PVDF-based polymers. An example film capacitor may comprise a high temperature fluoropolymer with dielectric loss lower than 0.2% and good film manufacturability. Polymer films can be stretched and orientated at least in one direction to make thinner films with improved performance. Film capacitors can be made by winding metallized films, plain films with metal foils, or using a hybrid construction where the dielectric films comprise the new compositions. Capacitors can also have a multilayer construction where the films are metallized.

Electromechanical Polymer Actuators

US Patent:
20110038625, Feb 17, 2011
Filed:
Aug 13, 2010
Appl. No.:
12/856035
Inventors:
Brian Zellers - State College PA, US
Shuxiang Dong - Beijing, CN
Shihai Zhang - State College PA, US
Qiming Zhang - State College PA, US
Assignee:
Strategic Polymer Sciences, Inc. - State College PA
International Classification:
G03B 13/34
G02B 7/02
US Classification:
396133, 359824
Abstract:
An adaptive lens comprises an actuator and a lens, the lens being mechanically coupled to the actuator so that energization of the actuator adjusts a focal point of the lens. The actuator may comprise a multilayer stack of electromechanical polymer (EMP) layers, having electrodes configured to apply an electric field across each EMP layer. The actuator may be operable to move and/or deform a lens, so as to adjust the focus properties of the lens. In some examples, the actuator has an annular shape, supporting a lens within the inner radius of the annulus. The lens position may be adjusted in an axial direction. In other examples, the actuator may be mechanically coupled a surface of a deformable lens, either directly or through another element of a lens structure. A strain applied to the lens modifies a curved surface of the lens, hence modifying the focal length of the lens.

US Patent:
20110110015, May 12, 2011
Filed:
Apr 11, 2008
Appl. No.:
12/082595
Inventors:
Qiming Zhang - State College PA, US
Qin Chen - State College PA, US
Xin Zhou - State College PA, US
Minren Lin - State College PA, US
Shihai Zhang - State College PA, US
Assignee:
The Penn State Research Foundation - University Park PA
International Classification:
H01G 4/06
US Classification:
361311, 29 2542
Abstract:
A multilayer film useful for capacitive applications comprises a high energy density layer and a dielectric blocking layer. In some embodiments, a conducting film is located between the high energy density layer and the blocking layer. The high energy density layer may be a fluoropolymer, such as a polymer or copolymer of poly-1,1-difluoroethene or a derivative thereof. The multilayer film may have high energy density (for example,. >8 J/cm) and low dielectric loss, for example less than 2%, and preferably less than 1%.

US Patent:
20110228442, Sep 22, 2011
Filed:
Mar 16, 2011
Appl. No.:
13/049423
Inventors:
Shihai Zhang - State College PA, US
Chen Zou - State College PA, US
Xin Zhou - State College PA, US
Qiming Zhang - State College PA, US
Assignee:
Strategic Polymer Sciences, Inc. - State College PA
International Classification:
H01G 4/06
US Classification:
361311
Abstract:
Examples of the present invention include high electric energy density polymer film capacitors with high dielectric constant, low dielectric dissipation tangent, and low leakage current in a broad temperature range. More particularly, examples include a polymer film capacitor in which the dielectric layer comprise a copolymer of a first monomer (such as tetrafluoroethylene) and a second polar monomer. The second monomer component may be selected from vinylidene fluoride, trifluoroethylene or their mixtures, and optionally other monomers may be included to adjust the mechanical performance. The capacitors can be made by winding metallized films, plain films with metal foils, or hybrid construction where the films comprise the new compositions. The capacitors can be used in DC bus capacitors and energy storage capacitors in pulsed power systems.
