▎ 摘　　要

NOVELTY - The surface plasmonic resonance/photothermal absorption evaporation chamber has: at least one transparent substrate (110) configured to receive light (102) on a first surface; nanostructures (120) disposed on a second surface opposite the first surface, where the nanostructures are configured to excite electrons in response to light; an inlet configured to provide a cold propellent (104) to the nanostructures; and an outlet configured to expel the propellent heated by the electrons. The nanostructures comprise nanocones, graphene oxide, chemically reduced graphene oxide, molecularly functionalized graphene oxide or chromium graphene oxide, and graphene or other photoabsorbing structure connected to a hydrophilic wick by a molecular linker. The evaporation chamber further has a cold propellent storage and delivery system configured to supply propellent to the inlet. The cold propellent is argon, xenon, water, methane or ammonia. USE - Surface plasmonic resonance/photothermal absorption evaporation chamber for use in an ion propelled device (claimed). ADVANTAGE - The thruster design is improved using surface plasmonic resonance/photothermal absorption. The evaporation chamber is configured to heat the propellant using conduction electrons. The nozzle exhausts heated propellent from the evapsoration chamber in order to produce thrust. The ion propelled device includes an opaque cover or variable opacity/transparency cover to control/eliminate incoming light. The propellent delivery system provides propellant from the propellent storage component to the evaporator chamber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an ion propelled device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a primary heat exchange/boiler for a surface plasmonic resonance/photothermal absorption effect thermal thruster. 100Primary heat exchange/boiler 102Light 104Cold propellant 108Hot exhaust vapor 110Transparent substrate 120Nanostructures
