Latest Patents
One of Denman's latest patents is for an electronic assembly with a charge-dissipating transparent conformal coating. This invention involves a coated electronic assembly that features a single-layer conformal coating overlying at least a portion of the electronic assembly. The conformal coating possesses a volume electrical resistivity ranging from about 10 to about 10 ohm-centimeter. It is composed of an organic polymeric binder and a variety of electrically semiconductive metal oxide filler particles dispersed within the binder. Notably, the binder and the filler particles maintain a similar visible-light refractive index. The binder may be a heat-curable or UV-curable urethane, while the particles can be doped with aluminum, magnesium, zinc oxide, or doped zinc oxide.
Another significant patent by Denman is for a radiator using a thermal control coating. This invention is designed for spacecraft that generate internal heat. The radiator element is in thermal communication with the spacecraft's internal structure and features a radiating surface coated with a white thermal control paint. This paint has an initial solar absorptance of no greater than 0.16 and an initial infrared emittance of at least about 0.80. The projected solar absorptance at the end of life is capped at about 0.33 for paints with an inorganic binder and about 0.6 for those with an organic binder.
